After your BU e-mail account has been transitioned from ACS to the Exchange 2010 server and if you are planning to use the same e-mail client after the transition, you will want to remove that client’s access to acs-imap.bu.edu in order to optimize your use of Exchange, as described below. If you are transitioning from ACS to Exchange but you are adopting a new/different e-mail client in the process, you will not need to take the steps outlined on this page and can simply configure your desktop or device mail client to use Exchange, if you have not already done so.

How to switch your mail client from ACS to Exchange in…

Mozilla Thunderbird

NOTE: You can use IMAP to access Exchange mail, which allows you to continue using Thunderbird if you wish to. However, please be aware that if you use Thunderbird as your primary mail client, you will have to use Outlook or OWA for meeting scheduling and you will not benefit from a centralized address list that’s available from every e-mail client you use. We recommend that you configure Outlook to have it ready as needed and to test out as the preferred alternative to Thunderbird use. If you do want to go ahead and continue using Thunderbird, you will need to switch your server settings, as described below:

  1. Launch Thunderbird
  2. Choose Tools -> Account Settings.
  3. Click on Server Settings below the account you will be changing. (It is probably called something like login@bu.edu where login is your BU login name.)
  4. Change the Server Name from acs-imap.bu.edu to xmail.bu.edu.
  5. Then, click on the Advanced button and make sure the “IMAP Server Directory” field is empty. If it is empty, click Cancel. If you see a /Mail in it, delete that to empty the field, and then click on OK.
  6. Next, go to the Outgoing Server (SMTP) setting area and, if you see acs-smtp.bu.edu as the setting, edit it so it reads smtp.bu.edu. Make sure you are using that with port 465.
  7. Click on OK.
  8. To be thorough, Exit/Quit out of Thunderbird.
  9. Launch Thunderbird again.
  10. If you have any problems, review set up your Exchange IMAP account to make sure your settings are correct.

  1. Launch Outlook.
  2. Choose from the menu Tools -> Account Settings.

  11. As a final step, check your “Junk E-mail” folder (or equivalent) to make sure no migrated messages went there by accident. If they did, you can move them back to your Inbox, or other folder, by dragging them.
