I have a few mailboxes I created way back in Exchange 2003 that are shared between several people, so after migrating to Exchange 2013 I decided to reconfigure those shared mailboxes “correctly” as actual “Shared” mailboxes. That was easy.

Then I discovered a small problem. Shared mailboxes only work when using the full Outlook client or through OWA. Up to now, Activesync was the primary method of accessing these mailboxes, and you can’t access a Shared mailbox using Activesync!

The reason is pretty simple. Shared mailboxes are created based on a disabled Active Directory user account. This is great for security, and also great because you don’t need a license for that mailbox. By disabling the AD account however, you have no way to authenticate using Activesync.

So here’s one that had me stumped. I can’t get ActiveSync connections working for some users on some devices. I’ve found a lot of posts around the internet talking about it being an issue related to self-signed SSL certificates, but I don’t think that is what my problem is.

The environment:

  • 1 x Exchange 2013 running on Server 2012
  • 1 x Internal private Windows PKI handling certificates
  • 3 x Active Directory based user accounts
  • 2 x Windows RT Surface tablets
  • 1 x iPad Mini
  • 2 x PC running Windows 8
  • 1 x iPhone
  • 2 x Windows Phone 7

A fair collection of devices to compare the issue across.

So what does/used to work?
