Why does Microsoft Exchange force the Alias to be 'FirstName Initial' then Last Name for teh E-mail address.


We have been using Microsoft Exchange 2007 for a little bit more than 1 year and this is the first time that I have come across this problem.  It’s not a big problem; but, I am afraid that it might be in the future.

At our company, we have Exchange setup/create email addresses to be 'First Initial' + 'LastName' (John Smith = Jsmith@domain.org).  Now, we have a new user, that I just created.  Lets say his name is 'Jason Smith' (Logon Jsmith); however, we already have another user named 'John Smith' (Logon 'Jsmith').  Hence there is a duplicate.  

What I tried to do is setup the new user with a logon of 'SmithJ' in Active Directory and that worked for his network logon  However, Exchange still set him up with an email of 'Jsmith2@domain.org).  Now, if I send the new user and e-mail it works; but, I must use the 'Jsmith2@domain.org' email address.  

This particular situation is not critical; however, this duplicate username situation may arise again.  My question is what can I do to force an email address to be different and not force a user to use an email address such as ‘Jsmith2@domain.org’ ?

What can I do to make 'SmithJ@domain.org' work, on a case by case basis?  Or any other suggestions?

On the properties of the mailbox in Exchange Management Console.  Under email addresses, uncheck thebox that says to update email addresses based on policy.

This will allow you to set your own address and delete the one you don't want without it being applied again.

Will that be for everyone going forward?  So, If Iwanted the old way back (Automatically 'First Initial + Last Name) I could just check that box again, whne I was finished creating the new user and things wold be back to normal?

Oh, I see.

 Uncheck box then edit
Uncheck th ebox, for this user.  Then edit the changes and there you are.

This worked very well.
