Owa is working for all domain users except for domain admins. How can we solve this problem? We user Exchange 2003 and we get the error ; You could not be logged on to Outlook Web Access. Make sure your domain\user name and password are correct, and then try again. Username and password are good ofcourse :-)

Something is probably pretty seriously messed up with your permissions. Though, actually, I would consider this a "feature" since your administrators should probably not have mailboxes in the first place. :-) Can these folks access Exchange through Outlook? If so, it may be the that the permissions on the \Exchweb folder has got a deny in place for Administrators or Domain Admins.Jim McBee - Blog - http://mostlyexchange.blogspot.com

I'am the administrator and have a mailbox. I've checked the permissions on the exchweb but it looks good.

Jim's referring to the fact that accounts that are members of "priviledged" groups (like Domain Admins) have permission inheritenc blocked on their user accounts. That prevents Exchange from receiving the permissions necessary to deal with the mailbox properly. The reason why user accounts with elevated permissions shouldn't have a mailbox will become evident the first time they open a message with an worm/virus/rootkit link in it. Those are bad enough when it's just a "normal" user but, oops! you just gave away the userid and password to the whole forest! --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
