Read guide →Quick answer: If Outlook on the web works but the Outlook app does not, the problem is usually local to the app, computer or account configuration rather than the mailbox being completely unavailable.
If Outlook is not receiving new mail
- Check mailbox and cloud-storage limits.
- Look in Junk, Other/Focused sections and filtered views.
- Review inbox rules and forwarding you recognize.
- Confirm Outlook is online and connected to the account.
- Test the account in Outlook on the web.
If Outlook cannot send
A message can remain in Outbox because of connectivity, authentication, a large attachment or an account/server restriction. Testing a simple message without an attachment helps narrow the problem.
Password prompts and recent password changes
If you recently changed the Microsoft or email-account password, the desktop app may still have an older credential stored. Re-authentication should happen through the legitimate account window; you should type your own password and verification code.
What remote support can review
We can review Outlook connection status, account setup, send/receive behavior, add-ins, common profile issues and local sync symptoms. Some mailbox-level restrictions or Microsoft-account security blocks can only be resolved through Microsoft or the organization that manages the account.

Frequently asked questions
Can you help if Outlook webmail works but the app does not?
Yes, that is often a good remote-support scenario because the account itself appears accessible.
Will you need my Microsoft password?
You should type your password and one-time verification codes yourself.
What if my Microsoft account is locked?
Only Microsoft can restore access to its account system. We can guide you to the official recovery path.
