Exchange 2007 SP3 with Update Rollup 1, 2 3A, and Rollup 5. Note when I download Rollup Pack 4 from MS (to assure we have rollup 4 which shows missing) , the download link shows and describes 4, but the file once downloaded it says 5.
Exchange working properly for all non-mac clients with Outlook version and Entourage works as well.
When installed Outlook 2011 I get the error below:
1. Account cannot be addeds. Note that Outlook 2011 requires Exchange Server 2007 SP1 Update Rollup 4 or later.
Looking through other posts, by EWS seem to return whats required. Looking for help to track this down. I have no feedback from the people who setup the server, but everything is installed on the same physical server which also is a DC.
