Handling a user moving between forest RRS feed

  • Question

  • Hi,

    Let's say I have two forests A and B with the respective domains A.com and B.com. There's a tree-root trust relationship between A and B. Both forest have their own Exchange servers. Now I have a user in the A forest with a @A.com email address. He's moving temporarily to the branch office using forest B. The main point is that he will now also need a @B.com email address and he will use both email address for different purposes. What's the best way to handle this situation ?

     

    Do I completely recreate both an AD and Exchange account in B and he will at the same time continue using its @A.com address somehow (OWA ?) ?

    Do I take advantage of the trust relationship and make him use its A AD and Exchange account and setup some kind of email alias from its @B.com address to its @A.com address ?

    Something else entirely ?

    I forgot to add that all servers are Windows Server 2003 (and Exchange 2003).

  • One option is create a mail-enabled user in forest B with @b.com address (note no mailbox, just mail-enabled acct) and then forward all mail from mail -enabled acct to forest A.

  • Hi,

    Agree with LMurthy. Usually, creating a mail enabled user is for onsite contract employees who require access to the network but who want to continue receiving their e-mail through their Internet service provider.

    Here is an article ‘Understanding Mailbox Enabled and Mail Enabled Recipients in Exchange 2003’, which describes the way to creating mail-enabled user in Exchange 2003.

    Hope this helps.

    Thanks

  • Hi Sophia,

    I've already stumbled upon this link while doing research. The trick is that it's not really a contract employee, it's an employee from another business unit. Hence the tree-root relationship between the forest.

    For the record, we've setup a domain account with a mailbox in our forest and we've asked the other forest's admin for the user in our domain to have access to its original mailbox.

    Thank you all.
