The GMAS training environment (https://gmastraining.harvard.edu) is refreshed on a weekly basis, on Sundays. It can be used for troubleshooting and for training. All of the data can be manipulated without any impact to real data that is used for reporting, and without sending false notifications to other users.
When sending emails to firstname.lastname@example.org, it needs to be sent from the University preferred email address to get to the clipboard. Preferred email addresses come from HR systems and can be viewed on a persons profile in GMAS.
