Free Up Mailbox Space to Receive the Reset Email

Clear out unnecessary emails and empty your trash folders so your inbox can resume receiving messages, including the password reset code.

If you are still logged into Outlook on a mobile device or desktop app, you can manually delete emails to free up server space. Once enough space is available, the Microsoft system will allow new emails to be delivered.

1
Delete large emails

Navigate to your Inbox, sort your emails by size, and delete unneeded messages with large attachments.

2
Empty Junk and Deleted Items

Right-click on the 'Deleted Items' folder and select 'Empty Folder'. Repeat this process for the 'Junk Email' folder to permanently erase these items from your storage.

3
Wait for storage synchronization

Allow a few minutes for the Microsoft servers to update your storage quota status.

4
Request a new password reset

Return to the Microsoft account recovery page and request a new password-reset email. It should now successfully arrive in your inbox.

Frequently Asked Questions

How long does it take for Outlook to recognize freed up space?

It usually takes a few minutes for the Microsoft servers to synchronize and recognize the newly available storage space, but in some rare instances, it can take up to a few hours for full functionality to be restored.

What happens to emails sent to me while my mailbox was full?

Emails sent to a full mailbox are typically rejected and bounced back to the sender with an undeliverable notification. They will not automatically appear once you clear space; the automated system or sender must issue a new message.

How can I check my Outlook storage limit?

In Outlook on the web, click the Settings (gear) icon, navigate to General, and then select Storage to view a detailed breakdown of your mailbox usage and available limits.
