We just installed a Windows 2003 Server and Exchange 2003 server. We can open Outlook Web Access for only the Administrator account and none of the others. I am moving mailboxes from an old Exchange 5.5 server, one at a time. I try to login as each one and it keeps asking me for the username and password.
It will ask for the username and password 3 times, I have used the username then password, then I tried DOMAIN\username and password. Only Administrator logs on perfectly.
I have tried adding Domain Users to the Internet group. I have tried just adding a brand new mailbox on the 2003 server to see if it is a migration issue. But it even the brand new mailbox will not open via OWA.
I can open all mailboxes seemlessly with Outlook on computers all over the company.
Any help is appreciated.
