Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Richard, thanks for posting here in Microsoft community, If Outlook isn’t accepting your AOL app password, try these quick steps, Double-check the app password, make sure you copied it exactly, with no spaces.
Also try to Use IMAP settings manually, instead of auto setup, manually enter AOL’s IMAP server settings in Outlook.
You can try also to clear saved credentials, simply go to Windows Credential Manager and remove any old AOL entries.
You can also try Outlook in Safe Mode simply run in Windows + R the Outlook.exe /safe to rule out add-in conflicts.
Also to isolate the issue, are you using Classic Outlook for Windows or Outlook from Microsoft 365, and have you successfully used this AOL account in Outlook before?
I hope this helps you, let me know
