What will happen to my artsci account when I activate my GO WUSTL email account?

On the day that you activate your GO account, Email that is sent to your @wustl.edu address will automatically be forwarded to your GO WUSTL account.

The following morning(after an overnight process between the two servers), Email that is sent directly to your artsci.wustl.edu address will begin forwarding to your GO account. Your artsci account will remain open so that you can backup or transfer any email folders you may wish to keep. Instructions for this and more are available at http://go.wustl.edu.
