I have an on premise Exchange 2010 SP2 environment, running in rich co-existance. We're running SSO and Dirsync. All is working flawlessly except for one thing.
If I create a new user in AD, run dirsync up to the cloud, and then enable the mailbox in the cloud, Autodiscover does not work for that user. The mailbox is fine, as access through OWA is okay.
If I create a new user in AD, create the mailbox on premise, and MOVE the mailbox to the cloud, Autodiscover works like a charm.
Microsoft has told me this is by design, and the move request stamps something that allows Autodiscover to work. This does not make much sense, in fact, it seems a bit backwards to me.
Can someone confirm this is by design, or is something missing? All Autodiscover entries on Public and Internal DNS are set accoring to Microsofts guidelines.
