The ACS Email service was retired on February 3, 2014 and acounts formerly hosted on ACS have been transitioned to either BU Google Apps or Exchange. However, the information on this page is being retained in case it is helpful.

NOTE: Instead of following the steps on this page, you can opt to forward your ACS mail to an external email account (commercial Gmail, etc.).  If you know that you do not want a BU Google Apps account and simply wish to forward your mail, you can proceed directly to the Email Forwarding System to make that change.

The step-by-step guide for transitioning from ACS to BU Google Mail

    1. Create a BU Google Apps account if you do not already have one.
    2. Once your account is ready, you should log in to any of the Apps linked from in order to make sure your access to the new account is working.

(Note: Faculty and staff are discouraged from taking steps 3, 4 and 5  since use of Exchange is recommended.)

  1. Next, configure your mail forwarding at where you will see an option to Choose BU Google Mail. Alternatively, you can manually forward your mail to
  2. Once you have set up forwarding, test it out. Send yourself a message to (where login is your BU login name) and make sure you receive it at and *not* on ACS.
  3. If you would like to be able to use a desktop or mobile device mail client in addition to the BU Google Mail web client, configure your mail clients so that they are accessing BU Google Mail. Important Note: If there is mail on ACS that you would like to move to BU Google Mail, for now you should leave working access to ACS in your desktop client(s) so you can drag messages between the two accounts. To set that up, simply add BU Google Mail as an additional “Account” in your desktop client.
