Not recieving emails

Common causes for not receiving Outlook.com email are:

1. Check whether mailbox or Microsoft cloud storage is full. If storage is full, email cannot be sent or received, and messages sent while storage was full are bounced back to the sender and are unrecoverable.
2. Check the Other tab and make sure messages are not being filtered there.
3. Check Junk Email settings and the Junk Email folder. If a message was marked as junk by mistake, right-click it and choose Mark as not junk.
4. Check whether messages are sorted incorrectly. In the message list, select Filter > Sort > Date.
5. Check whether email forwarding is enabled.
6. Check whether any email rules are moving, deleting, or hiding messages.
7. If the password was changed recently, update it. The account can also be temporarily blocked because of unusual sign-in activity.
8. If sign-in is failing, use the Microsoft account sign-in helper.

If email is missing only in the Outlook app, sign in to Outlook on the web and check whether the messages appear there. If they do, the issue is likely with the app sync rather than the mailbox.
