How to manage multiple Exchange mailbox accounts in Outlook

Some users have multiple e-mail accounts on the same server that is running Microsoft Exchange Server. Although you can only have one service in your Exchange Server profile, it is possible to access all of your Microsoft Outlook accounts without having to log on separately to each account.

To log on to one e-mail account (account A) and to have access to the mailbox for a different e-mail account (account B), follow these steps, as appropriate for the version of Outlook that you are running.

Note These steps assume that both accounts are on the same Exchange server.
