After I migrated my SBS2003 Server to SBS2008, I am unable to start Outlook 2003 for one specific user on a win2008r2 Terminal server. Outlook does not connect to the new exchange server.
Obviously the user didn't start outlook after I moved Exchange to the new SBS server and before I demoted the old SBS.
I get the error message "The connection to the Microsoft Exchange Server is unavailable" after ~20secs.
Button 'Retry' repeats the same message;
Button 'Work Offline' pops up another error message saying "Outlook can't be started" (or similar - I am trying to translate the german message) and Outlook is closed;
Button 'Cancel' closes Outlook as well;
There are no messages in the eventlog;
Other users are able to start outlook on the same computer.
I already checked a couple of hints, such as the RPC-Registry settings and they seem to be fine.
How can I reset the mail-account information for this specific user, so that he is able to reconnect to exchange?
I already tried to change and or remove various registry keys and values in HKCU/software/microsoft/exchange and HKCU/software/microsoft/office/11.0/Outlook but did not succeed.
