I just installed a new Exchange server into our organization running 2010 and I am in the process of moving all the server roles over to this server. (Our current server is running 2007)
So far everything is working EXCEPT for our users trying to connect to exchange via the Blackberry OWA method.
I added an external URL for our EWS virtual directory and it is running Basic Authentication, but I vaguely remember having to do something else similar in 2007 before it would work with our Blackberry's.
Can anyone refresh my memory?
