On one users computer I am having an issue where I get the follow error "Connection To Microsoft Exchange is Unavailble" I have deleted the users Outlook profile and the bad part is when I try to readd the profile it says the connection to Microsoft Exchange is Unavailble. I retried like 7 times in a row, then all of a sudden it went through and started loading the outlook profile and downloading emails. Then no more than 2 minutes later when i click the TO: button in an email it says it cant connect to Microsoft Exchange again. So there is an issue with pulling up the GAL as well as even configuring the profile for first use. Its not just this one mailbox because I had the same issue on multiple mailboxes. 1. I have uninstalled and reinstalled outlook 2007 2. I tried Installing outlook 2010 3. Deleted the users windows profile and recreated it from scratch and configured outlook. None of these have helped. This problem is really driving me nuts I have spent over 40 hours on it.
