Logging in to Lync 2010 with the Windows Phone client

Earlier today, Microsoft released the Lync 2010 client for Windows Phone (clients for Android, iPhone, iPad and Symbian are on their way).  And, as I’m an Office 365 user and I bought a Windows Phone last week, I decided to take a look.

Installing the app is straightforward enough but I was struggling to log in using the normal credentials that I use for other Office applications (like Outlook Mobile). From looking at the ratings on the app, it seems I’m not alone – with plenty of people saying “it doesn’t work”.

Microsoft’s advice for setting up Lync on Windows Phone is incomplete but the required DNS settings are documented in the Office 365 community wiki.  The missing piece of the puzzle came from Ben Lee – it’s necessary to specify a username (in the format user@domain.onmicrosoft.com) and an External Discovery URL of https://meet.lync.com/Autodiscover/autodiscoverservice.svc/Root.

Once those additional settings were configured, Lync jumped into life!

(For full client configuration details, with screenshots, check out Ben’s post.)

[Update 21 December 2011: It seems this also works with the iOS Lync client, except that also seems to need an Internal Discovery URL before it will allow sign-in (I used the same URL for both internal and external)]
