Important: If your Microsoft cloud storage is full, you cannot send or receive email. Check your mailbox storage to see what's taking up space. Learn more about recent changes.
If your cloud storage and mailbox are not full, and you can't send or receive email, or can't connect to Outlook.com, check these common causes:
-
If you can't send or receive email, check your account: update your password if it's been changed recently. Your account might also be temporarily blocked because we noticed some unusual sign-in activity. Learn how to unblock your Outlook.com account.
-
If you can't sign to your account, use the Microsoft account sign-in helper.
-
If an email is too large, you cannot send emails.
-
Check your Other tab and check there are no filters preventing you from seeing all your messages.
-
Check your Junk Email settings and your Junk Email folder. If there are messages that shouldn't have been marked as junk, right-click each email and then choose Mark as not junk to move them back to your inbox.
