I can't seem to connect on or off network to a brand new exchange server from a fresh install on a new mac... painful.
I get the error "Unexpected data was encountered" error code -17997 and not sure if I can really say much more.

Mac Mail works fine (to boot), and I've literally copy-pasted the user, server, etc from one to the other and outlook is still not functioning.

Anyone else? Is there some special "mac setting" that needs to be enabled on the server?

Running: Mountain lion, MS office for Biz, all updated and current. Permissions repaired, etc on my MBP-r.
We are rolling out a new Exchange server for a big client. The have mixed PC & Mac computers. We are also switching email domains in the process. The solution is to use profile switching to start fresh with the new server, & keep the old emails separate, but still functional. We can not do fast user switching, or have a separate user account on the computers for this. To our dismay, Outlook 2011 does not really support this. We are all attached to the same domain, & use AD. Not sure what we can do. Having both accounts active under one account is not going to wok for us. Does anyone know a 3rd party profile switch, or a work around to have 2 separate accounts under Outlook 2011?
