We recommend using the Gmail web interface to get the best experience with the PSU Google Mail account (firstname.lastname@example.org) associated with your Odin ID. However, if you decide that you must use a local mail client (eg. mail.app) on your Mac, you will need to configure it connect to Google Mail with your PSU Odin Identity. Get the details from OIT’s Advanced Email Settings page. If you are having problems, please contact OIT for support.
