Hello
patavana,
Thank you for posting here.
I understand that you are receiving an error message "mailbox quota exceeded" and this is the reason why you are unable to receive emails. Let me explain this to you briefly.
The reason for this error message is when your account's storage capacity exceeded the limit. Please be informed that the limit for free Outlook.com account is 5 GB and 10 GB for the Ad-free Outlook.com account. To solve this issue, you need to delete email
messages from your mailbox so you can free some space from your storage.
If the issue persists, please provide us the affected email address through the private message I created so we can investigate the issue on our end. Sign in and click the
Private Messages tab to view and to respond to my private message.
Regards.
