Securely Deleting Email

NOTE: The directions on this page explain how to permanently delete and then purge messages from your account. They should only be used to purge sensitive/secure emails so that they can no longer be recovered. It is recommended that you do NOT purge other emails from your account in case you need to recover them later.

When an email that contains sensitive information needs to be completely purged from your inbox, simply deleting the email isn’t enough. Deleted messages get moved to a Deleted Items folder, where they are held for 30 days and then automatically purged. Before the 30-day period is over, messages can be recovered or purged manually.

Purging an email from your account is a two-step process. First, you must “permanently delete” the email. Permanently deleting a message moves it to a Recoverable Items folder, which is hidden from view. Second, you must purge the message from your Recoverable Items folder.

1. Go to outlook.office365.com.

2. Sign in with your Tufts email address and password.

Although the Mac Outlook desktop application allows you to “permanently delete” emails, those emails will still be located in the hidden Recoverable Items folder, which you cannot access through the Mac Outlook application. Those messages can still be recovered.

If you wish to purge emails, follow the directions in the Office 365 Web Client or Outlook Web App sections above.
