Hello everyone, I'm quite new to the administering windows server so sorry if my question seems to be silly. In my network I've got two types of mail accounts - local, managed by active directory (let's say @abc.local) and global (for instance @abc.def.com). All users have access to the local mail service and some of them also can use global. One of my users could not log into the local mail, though I was sure it should work. So I started to experiment. In the 'active directory users and computers', in the user's properties, on the 'account' tab, on the 'user logon name' dropdown list I had two choices - @abc.local and @abc.def.com, from which @abc.local was chosen. I switched to the @abc.def.com, clicking OK. It obviously did not help and since then I can't get back to @abc.local, because it is simply not on the dropdown list any more! The mail account is still there - I've checked it in the POP3 snap-up. For a test, I've created a new user, created mail account for him in the POP3 service, switched to @abc.local in the 'user logon name', configured outlook and it worked. Then, I switched back to @abc.def.com in the 'user logon name' and now outlook asks for password and the domain password doesn't work. Is there a way to reconnect the user account to his mail account without deleting it? I'm out of ideas. Please help. I will be very grateful for any kind of help. Best regards:)

Hi ptrojan, Per your description, I want to verify something about your scenario. 1. Do your lcoal domain has a truted relation with your global domain, or as a sondomain with your global domain. 2. What about the global domain, is it a another domain in other place or hosted by others. 3. If above are all not right, does the exchange server is multiple domain hosted server. 4. Does the user have two mailboxs in the local domain and in the global domain. 5. Does the user log into the two domain and the email server using the same credential Regards! gavin
