Microsoft to Support CalDAV and CardDAV in Windows Phone!

But what about Windows 8, Windows RT, and Microsoft Office?

Well, here’s a shocker. Responding to customer needs, both Google and Microsoft have stepped back from the EAS cliff, and users of Windows Phone and Google online services will be well-supported going forward.

You may recall that Google infamously declared war on Windows 8/RT and Windows Phone customers in December when it revealed that it would drop support for Microsoft’s industry standard* Exchange ActiveSync (EAS) technology for free users of its Gmail, Google Calendar, and Google Apps services. I wrote about this development in Google Throws Down the Gauntlet, Kills EAS Support.

At the time, Google said that it would instead let customers access these services on mobile devices via protocols like IMAP, CalDAV and CardDAV, the latter two of which are not currently supported in Windows 8/RT or Windows Phone. Hence, the declaration of war.

But today, Microsoft revealed an agreement with Google, the results of which I have to confess I find somewhat surprising.

First, Google will extend support for new Windows Phone connections via Google Sync (that is, EAS) through July 31, 2013.

Second, Microsoft will build support for CalDAV and CardDAV into Windows Phone. Combined with existing support for IMAP (for email), this will enable Windows Phone users to continue to connect to Google services after July 31, 2013.

Amazing.

But there are three obvious questions, all tied to individual Microsoft products.

One, is this support coming only to Windows Phone 8? Or will Windows Phone 7.x be updated with CalDAV and CardDAV support too?

Second, what about Windows 8/RT? It’s a fair assumption that the People and Calendar apps in Windows 8/RT will be updated. But official word would be nice.

Third, Office? Will Outlook 2013 be updated for CalDAV and CardDAV support too?

Still, this is great news.

UPDATE: Now the Windows 8/RT team has posted something about this EAS changeover. Sadly, they're not explicitly promising to support CardDAV/CalDAV, which is odd since the point of the Metro apps is that they can be updated at any time. There is now a set of workarounds available for Windows 8/RT users at How to sync Google services with Windows 8 or Windows RT.

 

Note:

(* I’m not interested in pedantic comments about EAS not being a “true” standard. It’s a de facto standard. Deal with it.)

While I applaud MS and Google for ceasing their childish bickering (at least on this front), I'm more concerned with the question of whether or not users will actually GET the updates in anything approaching a timely fashion?

I know that Microsoft has promised to deliver updates directly to phones and skip the providers (thank God) and blah blah, but Portico is already appearing on some phones and not others, depending on brand and carrier. This is to say nothing of the Windows Phone 7.8 vapor...err..."update." Can we expect that Lumia 920 owners on AT&T will get it first, followed by HTC owners and then one day, far in the future, when the phase of the moon is just right, maybe a Verizon customer or two will get an unofficial update?

Bottom line: Hooray for agreement and updates...now prove it.

It makes no sense for the Windows 8/RT people not to eventually support Google's protocols. This is a flagship product we're talking about... what... how... why...? I can see these built in apps for which the general consensus is already negative dying fairly quick here.

Great news indeed! First it was HTML 5, now CalDAV and CardDAV. Microsoft has written a new chapter in supporting open standards.

I wonder if it means Google will re-expose the option in Google Apps to "turn on" Google Sync. This is a huge issue that I hope Paul you will look into and publicly shame Google about. I recently started using Outlook on desktop, but can't go into my Apps account to turn on Sync, and thus I can't sync Calendar.

Paul,
Any words on solving the sync issue for calender in Outlook2013 with google calender(s)?
For calender app in win8/RT, sync of exsiting google calender can be have by using the work around posted on superuser:
http://superuser.com/questions/464453/how-do-i-sync-multiple-g-calendars...

This works well for my computers.

Paul, funny thing about your comment regarding Exchange being a "true" standard or not... the irony is that it's as "true" a standard as Google's implementation of Cal/CardDAV. They've bastardized the standard beyond recognition.

Anyway, it's good that Microsoft (at least in part) is going to support it. People seem to forget that this is what put Microsoft on top in the first place... supporting pretty much everything when everyone else (Apple and IBM, mostly) were trying to lock people into closed systems. So maybe it is smart of Microsoft to release Office for iPad.

The REALLY funny bit is going to be when Google changes how this works behind the scenes and doesn't tell anyone and Windows Phones and Windows 8/RT devices just start silently failing all over the world. Can't wait.

So Google gave Microsoft an extension.

This gives Microsoft a chance to build into its systems the CalDAV and CardDav before they turn it off. Eventually everybody will need to move from EAS and that date is not announced yet.

Better than nothing I suppose.

How can Exchange continue to be a business standard, supporting only 3 emails accounts and fields for only one "mobile" phone and only 2 "business" phones? Google's and Apple's contacts implementations have unlimited number of emails and phone fields. If Microsoft's implementation of CardDAV will support unlimited fields (especially in Outlook and secondary in WP), then MS will gain points against competition.
