Updated Exchange 2003 to SP 1 to get rid of the '..titanium.. ' error. Now all users who could logon to Outlook Webmail can no longer authenicate. They can get to the site but log on fails:
"You could not be logged on to Outlook Web Access. Make sure your domain\user name and password are correct, and then try again."
System is SBS 2003 with no service packs (I took over this system from another company).
Need to solve the authentication issue.
