iPhone OS 3.0 is here, offering enhancements for enterprise Exchange ActiveSync

iPhone OS 3.0 was released today, and I’ve had a chance to play with it for a bit now. I am very impressed with the improvements Apple has made, and think that 3.0 will be much more welcome in Microsoft Exchange environments. However, it’s still not quite up to the high standard set by the BlackBerry.

Wondering how to get Exchange working in 3.0? Start here:
How To Set Up iPhone Exchange ActiveSync

For the most up-to-date information, see my iPhone Exchange ActiveSync Guide!

This post is part of my series focused on integrating the iPhone with Microsoft Exchange using ActiveSync:

1. A Few iPhone Exchange ActiveSync Gotchas
2. Can the iPhone Sync With Multiple Exchange Servers?

Major Changes

Apple made some significant updates to all three of the components touched by ActiveSync: Mail, Calendar, and Contacts.

• The Calendar has been totally re-done, more smoothly supporting multiple calendars, syncing with local calendars and Exchange at the same time, CalDAV and .ICS natively, and allowing on-phone creation of meeting invitations for Exchange users.
• The Contacts application can now sync with local address books and Exchange at the same time.
• Mail is more flexible, with per-folder downloading of Exchange messages.

As I noted last month, however, OS 3.0 is not all roses. In particular, the following issues continue to haunt the phone:

1. The iPhone only supports full ActiveSync with a single Exchange server. Although you are free to establish as many IMAP connections as you like, including connecting to Exchange with IMAP, you cannot use more than one ActiveSync service.
2. Still no notes and tasks sync (with Exchange). Although iPhone OS 3.0 does allow synchronization of notes with Apple Mail for Mac users, it does not support Exchange or Apple’s own MobileMe over-the-air services.
3. No public folder support.
4. ICS and CalDAV seems to be desktop-sync only.
5. Spotlight does not include full-text search of mail messages.
6. Push email remains slow, flaky, and battery-consuming. This is a very tough nut to crack!

Mail

The mail application gets numerous improvements for all mail servers. Notable among these is landscape mode and spotlight search. When it comes to Exchange ActiveSync, the changes are harder to notice. One thing that struck me was the ability to specify which folders to “push” along with the Inbox. Perhaps this was there all along and I missed it, but I never noticed it before.

Note that the Push settings have been moved under “Mail, Contacts, Calendars” in OS 3.0.

Calendar

OS 3.0 is much more sensible in organizing and synchronizing multiple calendar types

Although iPhone OS 2.0 supported multiple calendars, it was very confusing and not at all integrated with Exchange. OS 3.0 has cleaned things up significantly. As illustrated, the iPhone now organizes calendars into categories: Those synced from the Mac or PC and those synced over the air from an Exchange server.

That’s right – the iPhone can now sync calendar entries over both USB and Exchange at the same time! This is super handy, since iTunes supports CalDAV and ICS subscribed calendars through iCal on OS X, and presumably on Windows as well. I’ve written before about TripIt’s solid iPhone app, and this gives another way to view trips. But the iPhone doesn’t seem to support either CalDAV of ICS over the air, which is something of a disappointment. We can’t have everything, can we? Update: I missed it! iPhone OS 3.0 does include over-the-air CalDAV and ICS!

Of course, the new spotlight search supports calendar entries as well, allowing quick access to appointments.

Perhaps the most-anticipated calendar feature for iPhone OS 3.0 is meeting invite support. I can confirm that it is possible to create a meeting, add attendees, and send invites right from the iPhone, and that this works over the air! This is a specific Exchange feature, so of course it only works for the Exchange calendar. But you can easily change an existing non-exchange item to the Exchange calendar and start inviting attendees, even those not using Exchange.

But there are still limitations. You cannot add invitees to someone else’s meeting. You cannot make any changes to an appointment synced from the desktop (CalDAV and ICS included). You cannot forward a meeting request from the calendar app. You cannot see free/busy time when scheduling. It’s not like you have Outlook in your pocket!

One more weird thing I noticed: Nearly every app now has a landscape mode, including mail and contacts, but calendar is locked in portrait only!

Contacts

Like calendars, contacts now supports both iTunes and over-the-air Exchange syncing

The other application to see some updates is Contacts. Like the calendar app, Contacts can now sync to both local desktop and over-the-air Exchange sources at the same time. The iPhone sync combines desktop sources into an “on my iPhone” category and maintains Exchange contacts separately. It also includes access to an Exchange global address list (GAL), and this seems to work much better now than it used to.

Contact management is somewhat limited, however. If you locate a user in the GAL, you can’t add them to your Exchange or iPhone contact list without copy and paste (did I mention that it works?) or finding an email message from them. The phone also has no de-duplication features, so if your desktop contact list is synced with Exchange already you will have a world of duplicate entries.

Summary

All in all, iPhone OS 3.0 is a worthwhile upgrade, especially for business users. Everything seems to work more smoothly and logically than in 2.0, and the added Exchange calendar invite support is great. The complete set of additions, from copy and paste to spotlight search, are excellent as well. But, like the Mac, the iPhone remains just a bit left-of-center in the world of business and Microsoft Exchange. Maybe that’s for the best!

Well, a big gear turned again today as Google recalculated their calculated PageRank values for just about every domain and page on the Internet. This is only the third PageRank refresh of 2009, and it’s likely to shake up the standings of every Google search.

How It Works

Rehashing my previous post, which pointed out the perils Google faces in a world full of real-time links and nofollow tags, PageRank is one of the cornerstones on which the search giant relies. Simply put, every page gets a rank on a scale of 0 to 10 based on the number and quality of links pointing to it. Google also seems to rank whole domains this way, using the domain’s rank to weight the scores of pages contained there. Top-ranked sites like Wikipedia (PR 8 ) show up much higher in the Google search results pages than lower-ranked ones like fosketts.net (PR 5).

It certainly surprised me to learn that PageRank isn’t continually updated. In fact, it’s only recalculated every few months! The January refresh bumped my blog from PR 4 to PR 5, driving literally 1,000 more daily visitors my way! The calculation must take some serious horsepower, too, since Google doesn’t include the latest pages. Today’s refresh appears to stop at content from May 6, suggesting that it took the big brains in Mountain View three full weeks to complete their computations!

What It Means

You should care about your sites’ PageRank if you’re at all interested in attracting visitors. As I mentioned, a single-digit PageRank bump drove thousands of visitors to my blog in January, prompting my curiosity about this critical number. I’m not obsessive about it, but it is interesting to watch how PageRank affects site referrals. This is especially important for new sites, like my Enterprise Storage Strategies blog or Gestalt IT, since their readership expands rapidly as PageRank climbs upward.

If you own a web site of blog, you might be interested in checking your own PageRank. One simple tool is a JavaScript bookmarklet like the one from Google Blogoscoped. Just navigate to a page and hit the bookmarklet to see a popup with that page’s PageRank.

If you use WordPress, you can add a plugin like SlaptiGooglePR, which displays the overall site PageRank in the Admin Dashboard. It also includes the PageRank of individual pages to the Posts and Pages lists (which is how I knew which days were included in the calculation!)

At the end of the day, PageRank isn’t the most critical part of the Internet. But like a self-winding automatic watch, it’s really interesting to learn how Google does what it does, returning relevant links as if by magic.

Update: Google again recalculated PageRank on June 24, incorporating pages through the middle of June 16. They’re getting faster!

Note: This post is about Google, because it is by far the dominant search engine, advertiser, and “portal” in the English-speaking world. Nearly everything mentioned here applies equally to other search engines and advertising providers.

Ranking Pages

Google’s relevance comes from their historical ability to present a quality searchable portal to the entire Internet. The majority of Google’s revenue is also derived from quality information, giving them the ability to present more-compelling advertising to web users.

Google’s core success is based on its ability to discover and rank the quality of Internet content. Gmail, Reader, Picasa, Apps, and the rest of the Google properties are surely excellent sources of information on the preferences of individual users, but they contribute only slightly to the other side of the coin: Information about Internet content. For that, they still rely on the core technology invented at Stanford a decade ago: PageRank.

Every time it encounters a link, Google’s software “spider” follows it, adding the content of the linked web page to an index. Google, like other early search engines, counts each link as a vote for the quality of the page. The genius of PageRank is that Google weights each vote based on the quality of the page it comes from. Although PageRank is not the entirety of Google, it is a singular key element.

Put simply, Google’s success depends on its ability to gather and rank the links we all make and match them to the data we provide about ourselves. Without this, Google will fail.

The Changing Web

The graphical Web is not the Internet. My first experiences online came well before graphical hypertext clients (what we now call browsers) dominated the user experience and became the web. Although the network we call the Internet now supports a very wide variety of traffic, Google’s preeminence comes only from the Web. They have little or no reach into the massive streams of corporate data, multimedia, and other non-hypertext content streaming across the ‘net.

When it was first developed, the web was manual and links were hand-selected and carefully put into context. It was difficult to put together a web page, and those pages that were developed were were static. The social networks of the time (USENET, IRC, and email mostly) were not integrated into the web, did not generally include links. So the first search engines, and later ones like Google, focused on this relatively small pool of pages and links.

But the web soon became automated, subsuming most other interactive services. Social (user-generated) interaction moved into the web in a big way, with blogs, wikis, and discussion forums enabling rapid content creation and reference by users. Sharing links in the social web, and through social bookmarking services, generally replaced the manual pages of old.

At first, this explosion of user-generated content was a dream scenario for Google. They could harvest the collective intelligence of us all to identify and rank content. But as the number of pages and links exploded, the notion of a “web page” was radically shifted from a stable and predictable set of data to a dynamic portal into a vast store of content. Where everyone once saw the same content at a given URL, now each of us has his own experience.

Spammers and scammers realized the value of Google placement and flooded this dynamic social web with links. This threatened not only to undermine the relevance that supports Google’s search (and advertising) business, but it also threatened these new social services themselves. Each honest, relevant link added to a Wikipedia article, included in a Slashdot comment, or shared on a service like Digg was dwarfed by the thousands or millions of spam links injected to boost the PageRank of “client” sites.

I Don’t Follow

Google and the social net fought valiantly against this wave of link spam, but it became clear that something more radical was needed. The only way to fight spam was to make it useless to the spammers. Thus was born a simple but highly-effective tool: Nofollow.

Webmasters long had the ability to tell the Google spider to ignore a certain set of hosted pages through the use of a server-side list called robots.txt. But spammers wanted the exact opposite. What was needed was a client-side way to specify that a link was not worthy of being spidered and ranked by the search engines. This would eliminate the primary benefit of link spam.

Implementing client-side spider blocking was trivial: A simple tag, “rel=nofollow”, was added alongside the url in a web link. This way, Google’s spider would simply ignore every “nofollow” link it encountered, and they would never be searched or ranked in the index.

But spammers would never put the nofollow tag in their own links. So sites quickly began implementing blanket nofollow policies: Every link submitted by users in any form would receive the tag by default. The idea would be that links that had not yet been vetted by users would get the nofollow tag and those that were deemed acceptable would not. But most sites never figured out the right process to allow the nofollow tag to be removed. Today, nearly every social service, from FaceBook to Twitter to Digg to StumbleUpon, permanently marks nearly every link this way. Even Wikipedia, a long-time holdout, finally switched to a default nofollow on all but the English site.

The Nofollow War

What does this mean for Google? If the vast majority of user-generated links are tossed into the spam category as far as the search engine is concerned, it means that their entire system of discovering and ranking links is in jeopardy. The major social services, most of which attract the majority of end-user traffic, content, and links, are rendered useless in generating relevancy.

But these are the exact sources that Google ought to be focusing on the most. Many have noted that they hear about news more rapidly through real-time sources like Twitter than through less-dynamic traditional news sites and blogs. Even if Google had the ability to spider a service like Twitter in real time, which is doubtful, they would gain no insight from the links included in these sources. Social bookmarking sites like Digg are chock full of user-vetted links and should be gold mines for Google, but the nofollow tag makes them invisible.

This scarcity of user-generated links has made the links that are followable even more valuable. Scammers constantly create fake blogs of scraped (read “stolen”) content and users are paid to include followable links anywhere they can. Sites with a high PageRank value are constantly inundated with offers and attacked by hackers to siphon off high-value “votes”.

High-profile content providers are circling their wagons, drastically cutting down on outside links in order to focus PageRank on their own properties. Smaller publishers and blogs are striking back at the big guys, decrying their dearth of external links. Some even go so far as to initiate blanket nofollow policies against these big, respected, but non-linking sites.

This leaves Google with even fewer useful links with which to examine the Web. It also leaves the biggest content providers and networks and the savviest search engine optimization (SEO) pros with a bigger slice of the valuable top-of-Google result real estate.

The Fix Is In

Google is left with a looming nightmare scenario: As smaller, alternative, social, and real-time content providers disappear from the search engine, its overall relevance and value declines. Soon, a tipping point will be reached when users would rather rely on Twitter, FaceBook, and the rest for their Internet interactions than the old-fashioned search engine, email, and RSS readers that Google currently dominates. This house-of-cards collapse can only be avoided by including user-generated content in the Google index.

Search engines could simply ignore the nofollow tag, wading into the social stream and combatting spam in other ways. But this would lead to another rapid upswing of link spam, shifting the burden to content providers once again. And it might also expose links that actually should not be followed, leading to technical and even legal trouble.

The best solution would see the social networks designing in some method of removing the nofollow attribute once links are verified to be relevant and correct. But there is no incentive for them to help drive Google traffic to other sites. Indeed, Twitter recently took the next step, arranging the titles of user pages in an attempt to SEO their way to the top page of Google searches for user’s names. Only altruistic systems like Wikipedia are likely to design in this type of response.

Another possible scenario (to be explored another day) is the usurpation of today’s social web and its content by a new next-generation service. A web-based social client like FriendFeed could rapidly siphon away both existing and net-new content and users in the guise of openness and interoperability. Although new web spiders like Cuil have failed, perhaps old-fashioned crawling capability is no longer all that valuable in the social web.

The most likely fix is both predictable and pragmatic: Google must buy all successful source of social links (like Twitter, Bit.ly, StumbleUpon, and even FaceBook) and integrate them into their search system. Owning Twitter would enable Google to decide which links to follow and which to ignore. The reward of improving search results would be the incentive needed to add “re-follow” capability. Buying these services would also give Google an open pipe of the real-time traffic flowing through these services, a critical resource that they currently lack.

Google simply can not afford not owning the real-time web, and they must continue to buy up similar sources of content as they appear. Yahoo was unable to extract value from StumbleUpon, but Google’s other competitors will certainly try to undermine the search giant. Frankly, I’m shocked that Microsoft, FaceBook, or even Baidu have not yet snapped up services like Twitter, LinkedIn, and Digg even if only to keep them and the information they contain out of Google’s hands.

iPhone OS 3.0 is coming, offering enhancements for enterprise Exchange ActiveSync

As the release of iPhone OS 3.0 nears, I set out to discover how the new OS changes the iPhone’s ability to synchronize data with Microsoft Exchange servers using ActiveSync. What follows here is my deductions so far, and is of course subject to change when the new OS is released!

For the most up-to-date information, see my iPhone Exchange ActiveSync Guide!

This post is part of my series focused on integrating the iPhone with Microsoft Exchange using ActiveSync:

• iPhone OS 3.0 information:
  1. First Look: iPhone 3.0 And Exchange ActiveSync Integration
  2. How To Subscribe To Internet Calendars In iPhone OS 3.0
  3. How To Access LDAP Directories In iPhone OS 3.0
  4. iPhone 3.0 Exchange ActiveSync: Better But Not Perfect
• How To Set Up iPhone Exchange ActiveSync
1. A Few iPhone Exchange ActiveSync Gotchas
2. Can the iPhone Sync With Multiple Exchange Servers?

New ActiveSync Features

1. iPhone OS 3.0 allows users to create meeting invitations! Finally, right from the phone, you will be able to set up meetings, select invitees, and send invitations. Initial reports are that this functionality is definite and fairly complete.
2. Enhanced mail search includes contacts, messages, and even mail still on the Exchange server! This is a huge and welcome addition. No longer will you be frustrated that the iPhone didn’t download that one important message from last month, and no longer will you have to scroll around trying to locate it! This is integrated into the new Spotlight screen: Flick left from the home screen and you’ll be able to search email, contacts, calendars, and all other phone content! But Spotlight only searches message metadata, not message content.

New Related Features

1. The calendar app supports CalDAV and ICS calendars as well as ActiveSync, making it much easier to use Google, Yahoo, and TripIt calendars. But these probably will not be integrated and synchronized with the ActiveSync calendar, leaving you in multiple-calendar hell.
2. Peer-to-peer contact exchange using BlueTooth seems certain. Since the iPhone gracefully integrates on-phone changes with ActiveSync contacts already, this will be a welcome way to build out one’s Exchange address book.
3. Cut, copy, and paste are definitely in, and will work in the mail, contacts, and calendar apps!
4. The mail app now supports landscape mode, with its larger keyboard.
5. A new API for email within applications would be compatible with Exchange, allowing a new family of corporate apps and possibly mitigating some of the missing features. I can imagine someone developing a far more feature-packed email client which embeds the native email client and extends its support to public folders, for example.
6. iPhones running 3.0 appear to allow automatic on-demand connections to VPNs. Again, not specifically an ActiveSync feature, but this would make the process of accessing a firewalled Exchange server more friendly.
7. OS 3.0 supports LDAP servers. Although this is not an ActiveSync issue per se, it could allow a workaround for the single-ActiveSync issue (which remains). LDAP contacts would make the basic IMAP email connection with a second Exchange server somewhat more tolerable. But it’s not yet clear if LDAP contacts are all that functional in 3.0, or whether they’ll make the cut at all.

Bad News

1. The iPhone will remain limited to full ActiveSync with a single Exchange server. Although you are free to establish as many IMAP connections as you like, including connecting to Exchange with IMAP, you cannot use more than one ActiveSync service. However, as noted above, 3.0 does include LDAP support so at least the contacts from your second Exchange server might be accessible.
2. Still no notes sync (with Exchange). Although iPhone OS 3.0 does allow synchronization of notes with Apple Mail for Mac users, it does not appear to support Exchange or Apple’s own MobileMe over-the-air services.
3. Spotlight does not include full-text search of mail messages. Although it’s nice to be able to search through everything on the iPhone, and even content on the Exchange server, you still have to remember the sender, subject, etc.
4. Battery life is poor with Exchange ActiveSync push and the new push notifications enabled. iPhone push battery life has been a problem for quite a while.

As the iPhone OS 3.0 release nears, I will keep my eyes open for enterprise Exchange ActiveSync features and post them here. Subscribe to my Apple feed for up-to-date details!
