Ran into a problem today with an Outlook 2010 client that would not leave the “disconnected” state. I restarted the computer, verified the mailbox was still active in Exchange 2003, and verified that this problem was not effecting other users, even ones on the same PC. I tried to create a new outlook profile, but during the setup I kept getting the same error:
“Microsoft Exchange Server reported error: The server is
not available. Contact your administrator if this condition persists”
It appears that just this one user cannot connect to exchange, the way that we solved this problem was by increasing the maximum number of connections that each user can make to Exchange 2003. Follow these steps on your Exchange server:
- Open Regedit
- Navigate to HKLM\CurrentControlSet\Services\MicrosoftExchangeIS\ParametersSystem
- Create a new DWORD called “Maximum Allowed Sessions Per User” and set it to decimal 64.
- Restart the “Microsoft Exchange Information Store” service
- Attempt to reconnect with the user’s outlook.
Hopefully this took care of your problem user.
