I have an Exchange 2007, with users on Outlook 2007 fully updated.
I have made a hybrid configuration to O365 with an Exchange 2010 in between.
My problem is that any given user that already has an Outlook profile on their computer, doesnt reconfigure servername in the profile.
If I create a new profile in Outlook 2007, it just configures automaticly with the correct o365 servername.
Why is the Exchange 2007 not reconfiguring my clients?
