Common Outlook problems and how to fix them

Account recovery

Use account.live.com/acsr to recover a Microsoft account when normal reset fails; fill in as many past passwords and contacts as you can recall.

Password reset

Reset at account.microsoft.com; add a backup email and phone so future resets don't require the full recovery form.

Can't send or receive

Check you're not over quota, review Junk and Blocked senders, and confirm mail-app settings (IMAP/SMTP) match Microsoft's current values.

Hacked account

Change the password, review recent activity at account.microsoft.com/security, and remove unfamiliar app passwords and forwarding rules.

Sync issues on phone/desktop

Remove and re-add the account, or update the Outlook app. Server-side, ensure the mailbox isn't full.
