Background

Since Microsoft is offering Office 365, I’m a hugh fan of it, but it’s only since yesterday that I migrated my PIM solution from Kerio Connect to Office 365.

I choose the Office 365 E3 subscription because I do IT and this one offers advanced IT configuration and control, an Office Professional Plus license and Active Directory integration.

In my configuration, I keep my old mail sever running (because over the years I have created many anti-spam custom routing rules) and forward all e-mail to user@domain.onmicrosoft.com. I also added my own vanity/custom domain to Office 365. All pretty much as described in the Simple Domain Sharing for SMTP Email Addresses article. Step 3 of that article tells you to change your primary e-mail address to the one of your own domain. This is an important step, because it will change your user name for all services. Now I have have Outlook w/ Exchange, SharePoint and Lync on the PC and it all works fine.

But with Lync 2010 Mobile on the Windows Phone, it was another story. The client kept saying ‘Can’t connect to the server’. This post describes what I did to fix it for myself.

Configuration:

2 domains:

domain.onmicrosoft.com
domain.com (set to shared, but as primary; explained in steps 2 and 3 here)

Steps:

Start Lync 2010 on Windows Phone
Enter sign-in address: user@domain.onmicrosoft.com
Enter your password
Check ‘Remember my password’
Enter User name: user@domain.com
Toggle ‘Auto-detect services’
Leave the internal discovery address blank
Enter the external discovery address: https://meet.lync.com/Autodiscover/autodiscoverservice.svc/Root
Save the configuration

This should work. Have fun!
