Losing contacts and calendar details after moving away from Amazon WorkMail can be frustrating. Usually, when a user is permanently deleted from the system, you can’t recover the entire account, but you might still be able to retrieve some email messages if they are in the Deleted Items folder of a still-active mailbox.
If you’re looking to back up or transfer your emails and other data, Amazon WorkMail offers a mailbox export feature. This allows you to export mailbox content to a PST file, which can be handy for backups or migrating to another system later on. Keep in mind, however, that the standard instructions mainly focus on active mailboxes, and recovering data from a deleted account within 30 days can be more complicated. The process and options for doing this are not always clearly detailed in the official guides.
Since your situation involves recovering contacts and calendar data after the user account has been deleted, your best move is to contact AWS Support directly. You can reach them through the AWS Support Center at this link: AWS Support Center. They can review your case and tell you whether restoring the account or retrieving specific data is still possible within the 30-day window. They can also advise on any available export options for your situation.
Support for Amazon WorkMail will end on March 31, 2027, so it’s good you’re already working on migrating. For future safety, it’s always a good idea to export important data, including contacts and calendars, before deleting any user accounts.
