What happens when you exceed your Microsoft storage quota
If you exceed your Microsoft storage quota, some Microsoft services stop working.
- OneDrive: You can't upload, edit, or sync new files, including files from your camera roll. Your existing files remain, but they're read-only.
- Outlook.com: You can't send or receive email if you exceed either your cloud storage quota or mailbox storage quota. Incoming emails are returned to the sender and must be resent after you free up or buy more storage.
- Microsoft Teams: You can't send or receive messages that contain attachments.
- After three months: If you remain over your OneDrive storage limit, your OneDrive account is frozen.
- After six months: If you remain over your OneDrive storage limit, Microsoft might delete your OneDrive and all files in it. Deleted files can't be recovered.
