Hi Steve Traynor,
In Classic Outlook, an AOL IMAP mailbox syncs its folders from the mail server, so a folder can fail to delete in the app or it can come back after sync. The most reliable fix is to remove (or rename) the folder on AOL webmail first, then let Outlook re-sync.
- Close Outlook.
- Sign in to AOL webmail and delete the unwanted folder there. If it will not delete cleanly, rename it first.
- Reopen Outlook and allow a few minutes for the folder list to sync and refresh.
If the folders are directly under Inbox and sync seems “stuck,” there is a supported workaround to rename (or remove) Inbox subfolders in AOL webmail, then restart Outlook.
For reference: Outlook stops syncing AOL email
If the goal is only to stop seeing the folder (not delete it), you can unsubscribe from it in Classic Outlook:
- Right‑click the top folder of the IMAP account > IMAP Folders > Query > select folder > Unsubscribe.
If AOL webmail already looks correct but Classic Outlook still will not reflect changes, removing and re‑adding the AOL account in Outlook can clear a sync/config issue.
If you share whether the folder deletes then reappears, or if you get a specific error, the next step can be narrowed to that exact symptom.
