I'm having a rather confusing problem.
I've moved a clients exchange server to Office 365 from SBS 2008 (Exchange 2007) as we'll shortly be migrating to a Server 2012 environment.
The problem is that when I set up an account from a users desktop (using autodiscover) the mailbox is found but the password will not except. This only happens from within the local network. If I create a profile on my personal computer (not attached to any domain) everything works just fine.
I've since shut all the exchange services and IIS services related to exchange off.
still no luck.
Any help would be greatly appreciated.
