Quick answer
Deleting an Outlook folder can remove its messages locally and, for synchronized mail, on the server. Recovery from Trash is not guaranteed.
Applies to
For an authorized mailbox user. Interactive Online manages settings only for mail hosted on the selected service; mail hosted elsewhere uses that provider's settings. The preserved lesson shows an earlier interface.
Steps
- Open the intended application or account and confirm its complete mailbox address and provider.
- Preserve needed messages, confirm the exact account/folder and review Delete Folder. Check the current retention and recovery behavior before confirming.
Check the result
Confirm the intended folder outcome on the relevant devices. Keep the recovery export until the result is accepted.
Troubleshooting and support
Outlook 2016 is out of support. If required messages disappear, stop further changes and check actual recovery options before emptying deleted items.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
