I just added a second user to my Exchange 2010 box, it is in coexistence with exc2003. My account is already set up and working with a personal archive folder.
The user I just set up however is unable to see the archive in Outlook. It is visible in OWA but not outlook. I have created a test profile on my PC with the users account and still no archive, if I jump back to my profile on the same box the archive is there so I know it is not an office versions issue.
I have deleted all profiles from Outlook (one of which worked with the archive) now any new profiles including my own no longer show up. I think I have broken something In exchange. I get an auto discover certificate error which I am in the process of fixing. Perhaps the 2 problems are related. Also OWA on this server runs on a custom SSL port.
