See How long will my account remain active after I've left UMBC? for information about account deactivation and deletion timelines.
If you are still affiliated with the University
Accounts scheduled for deactivation are sent an email to inform you of the deactivation. You can reply directly to that email indicating how you're currently affiliated (e.g. undergraduate student, faculty, staff). You may also contact the /wiki/spaces/doit/pages/30574803 or submit a support request using the Request Help link to the left.
If you are no longer affiliated with the University but would like to request temporary access to your account
You can request that your account be reactivated for 90 days by visiting https://webadmin.umbc.edu/admin/Accounts/Renewal
Temporary account reactivations are granted once per user. If you need to have your account for longer than 90 days, we recommend having your account sponsored. Read more at How do I request myUMBC accounts for non-UMBC users / Create a Sponsored Account?
