Outlook.com automatically regenerating corrupted draft messages

Question

My Outlook.com mailbox is automatically recreating draft messages every few minutes. This draft appears with "[Draft][Unknown]" and regenerate even after deletion.

I have already:

Changed my password

Enabled two-factor authentication

Signed out of all sessions

Checked activity (no suspicious logins)

Removed forwarding

Checked rules (none)

Disabled POP/IMAP

Cleared Deleted Items and Recoverable Items

Tested with phone offline and in private browser

The draft still regenerate server-side.

This appears to be mailbox corruption in Exchange and likely requires a backend mailbox repair or reset.

Hi Michele Parry,

Thank you for reaching out to Microsoft Q&A forum.

I understand how frustrating this is—especially when the draft keeps coming back even after you’ve secured your account and tried all the usual cleanup steps. When the same behavior continues across devices and browsers, it can be extremely stressful and disruptive.
