One AD user, Two Exchange Mailboxes
Posted on 2016-08-04
I have an Exchange 2010 Server hosting email for 2 companies (abc.com and xyz.com)
I have one employee who "works" for both companies.
I know in EMC, I can edit her mailbox, click on the Email Accounts tab and add the second email address.
Now, whether someone emails email@example.com or firstname.lastname@example.org, they all go to her mailbox.
The problem is, for a mailbox you can (obviously) only have one "default" reply email address.
If someone emails her at email@example.com and she clicks 'reply', I want her reply-to email address to be 'firstname.lastname@example.org' with her 'email@example.com' email signature.
Likewise, if someone emails her at firstname.lastname@example.org and she clicks 'reply', I want her reply-to email address to be 'email@example.com' with her 'firstname.lastname@example.org' email signature.
I know there is a way to change the 'from' address right before sending an email, but it's not practical.
So what I want to do is create two separate Exchange mailboxes for this user.
Mailbox 1 is email@example.com
Mailbox 2 is firstname.lastname@example.org
In Outlook, she can have 2 mailboxes mounted.
And since the mailboxes are separate, emails sent to each .com are kept organized, and emails sent from either .com will use the appropriate 'from'/'reply to' email address.
In Exchange 2010, is there a way to create two mailboxes for one Active Directory user? Or do I have to create two AD user accounts for this one employee - each one having its own mailbox and its own properties?
I am hoping to be able to create the second mailbox WITHOUT having the overhead of a second AD user account.
She will never log into the second AD account. Its only purpose would be to attach a mailbox to it.
