All, When I first installed exchange2k, it took me approximately 3 - 5 days (there was a weekend thrown in there) where noone could access their folders, the Exchange server would not recognize the users to authenticate them. The same thing happened for Instant Messaging. Is this a replication option? If so, where can I change this? Also, one of our IMS users can't login to the IMS server (Instant Messaging Service). Everything looks good on their account, I removed the home server, recreated the home server (for the account), reinstalled the client, and still no success, any suggestions?
