In our environment, OWA is only available internally. However, there is a mailbox that multiple people must work from in addition to their own. The way we have chosen to work is to have this mailbox open in OWA. Unfortunately, on one computer only, it logs the user straight into their own email. If you click log out, it goes to the standard logged out window that tells you to close internet explorer. Next time you access the OWA address, it takes the user straight in to their webmail without asking for userid and password as if you had never logged out. On all other profiles and computers everything works fine. I tried recreating the cached profile on the client, but it made no difference. Any ideas?
