This article explains what will happen to a user's Gmail account when they leave or retire from Virginia Tech.
You will not have access to your Gmail account once you are no longer affiliated with Virginia Tech. This loss does not include retiree or alumni.
If you're only affiliation is employee (not retired or alumni) then you lose access to Gmail once you are no longer affiliated with the university. For W2 and other business concerns, your access to Gmail will last for 18 months after loss of affiliation. You will receive several emails before your account expires. It is your responsibility to ensure that any emails are forwarded to a personal account of your choosing.
If you are, or become, an alumni or retiree, however, then you will continue to have access to an email account through VT Google Workspace Mail. Incoming mail is automatically routed to this account once your affiliation changes. Existing Exchange Online mail is NOT moved AND the account mailbox will be deleted, so please make arrangements ahead of time if you wish to keep any correspondence from your Exchange Online account, if applicable. If you were forwarding your VT Gmail account to your Exchange account, then you will need to disable that forwarding.
