Clear Outlook and OneDrive Storage to Restore Email Delivery

Freeing up space in your Outlook mailbox and connected OneDrive is required to allow incoming emails, including the Microsoft 365 invitation, to be delivered to your inbox.

Microsoft shares your total storage quota across OneDrive and Outlook attachments. If either of these reaches its limit, your ability to send and receive emails is temporarily suspended.

Check Current Storage Usage

Open your web browser and navigate to https://outlook.live.com/mail/0/options/general/storage. Log in with your Microsoft account to view exactly what is taking up your space.

Delete Unnecessary Messages and Attachments

From your Outlook inbox, sort your emails by size. Delete older messages that contain large attachments, as these consume the most storage space.

Empty Junk and Deleted Items

Right-click on your 'Junk Email' and 'Deleted Items' folders in the left sidebar, and select 'Empty folder' to permanently remove these files from your server.

Run the Mailbox Cleanup Tool

Visit the official Microsoft cleanup guide at https://support.microsoft.com/office/792b521c-3f4e-404e-b436-9c197bad6f45 and use the built-in sweep features to automatically archive or delete old emails.

Accept the Resent Invitation

Once your storage is below the limit, email delivery will be restored. Ask the subscription organizer to resend the Microsoft 365 Family invitation so you can accept it.

Clear Outlook and OneDrive Storage to Restore Email Delivery

Delivery Delay: It may take a few minutes for Microsoft's servers to recognize the cleared space. If you still cannot receive emails, wait 15 minutes and refresh your inbox.

Frequently Asked Questions

Why did I stop receiving emails in Outlook entirely?

If your Microsoft account storage (which includes your OneDrive files and Outlook attachments) exceeds the free quota limit, Microsoft automatically blocks your account from sending or receiving any new emails until space is freed up.

Can the organizer bypass the email and send a direct link?

Yes. The person organizing the Microsoft 365 Family subscription can log into their Microsoft account dashboard, generate a direct sharing link instead of an email invitation, and send it to you via a text message or chat app.

Will I eventually receive the invitation email that was sent while my storage was full?

Usually, emails sent to a full mailbox bounce back to the sender and are not queued for later delivery. You will likely need to ask the organizer to send a fresh invitation after you have cleared your storage space.
