Solution 1Recommended

Verify Outlook and OneDrive Storage Limits

Check if the newly purchased storage has been applied and remove unnecessary files if you are still over the limit.

Your Microsoft storage quota applies to your personal Microsoft account and includes OneDrive files, Outlook.com attachments, and Microsoft Teams data. Even if you have not exceeded your specific email limit, exceeding the overall Microsoft storage limit will prevent you from sending or receiving emails.

1
Sign in to Outlook

Go to Outlook.com and log in with your Microsoft account credentials.

2
Access settings

Click the gear icon in the top right corner to open Settings, then select 'View all Outlook settings'.

3
Navigate to storage

Click on 'General' in the left-hand menu, then select 'Storage'.

4
Review available space

Check the available space in both Outlook and OneDrive. If either limit has been exceeded, delete unnecessary emails, large attachments, files, or items in the Recycle Bin to free up space.

Frequently Asked Questions

Why can't I send emails right after buying more Microsoft storage?

It can take up to four hours for a newly purchased storage subscription to sync and apply to your Outlook.com and OneDrive accounts. You need to wait for this processing time to complete.

Will I receive the emails that were sent to me while my storage was full?

No. When your storage is over the limit, incoming emails bounce back to the original sender with an error message. The sender will need to resend those emails once your storage space is restored.

What items actually count towards my Microsoft storage limit?

Your Microsoft storage quota includes OneDrive files and photos, Outlook.com attachments and inline images, items in your Recycle Bin, and Microsoft Teams message attachments and recordings.
