Can't create "service" user in Exchange 2000

I have a Windows 2000 server with Exchange 2000.

I'm planning to switch from using my ISP for email to hosting my own email.

With the ISP I had an alias called

I'm trying to creat a distribution group in Exchange and it won't let me.  It says the name already exists.  I've looked through all of the users and don't have anything called "service".

Is this an account that Exchange uses by default for something and can it be changed b/c I can't change that one alias.

The account probably does exist in your Active Directory. I suggest that you do the following:

Go into LDP and do a search for cn=service

I am pretty sure that is one of the magic words that you cannot use. There are a few that cannot be used.
Try creating an account called something else (Service User) and then attaching to that account.

If it still will not let you, then enter in to Outlook and see what it resolves to.
