Outlook 2007 is installed on an sbs 2008 server. i am continuously prompted for the mailbox username and password. the exchange profile uses the admin account. although i enter correct credentials the prompt continues.
have discovered that if i uninstall windows update kb960803 – security update for 2008 x64, I am no longer propted for credentials.
I would prefer to leave this update on the server.
How can I resolve this issue?
