A Microsoft file hosting and synchronization service.
If Microsoft storage is over quota, these effects can happen:
- OneDrive becomes read-only and cannot upload, edit, or sync new files.
- Outlook.com cannot send or receive email if either cloud storage or mailbox storage is over quota. Incoming mail is returned to the sender until storage is reduced or more storage is available.
- After 3 months over the OneDrive limit, the account can be frozen.
- After 6 months, OneDrive files may be deleted and are non-recoverable.
Based on the symptoms described, the most relevant checks are:
- Sign in to the Microsoft account dashboard and open the Microsoft storage section to verify total cloud storage usage and quota.
- In OneDrive, open Manage your OneDrive storage to see what is taking space and empty the Recycle Bin.
- Check whether a shared folder in OneDrive is counting against the account storage.
- Check whether the storage quota changed because a subscription expired, renewal failed, or a promotion ended.
- If 100 GB of storage was just purchased, allow time for the quota to update. After purchasing additional OneDrive storage, it can take up to 24 hours for the new quota to appear. If it has not updated after 48 hours, contact support.
- If the OneDrive account is already frozen, delete files or buy more storage, then allow up to 2 hours for changes to apply. If still frozen after 4 hours, contact support.
What counts toward Microsoft storage includes:
- OneDrive files and folders
- Items in the OneDrive Recycle Bin
- Outlook.com attachments and inline images
- Microsoft Teams message attachments and recordings
A Gmail account is not covered by Microsoft storage guidance in the available information.
