I have exchange server 2003 running several mailboxes. I am having issues with a certain private mailbox. This certain user's mailbox is only accessible through ms outlook when logged locally on the domain. The problem lies with this mailbox not having outlook web access. When accessing the mailbox through http://"server"/exchange/"user" an error of HTTP/1.1 404 Resource Not Found occurs. Now I checked system attendant for this user's mailbox and made sure that the exchange feature of outlook web access is enabled, using default protocols. Every other mailbox has not issues accessing their mail through owa except this one.
