Frequently Asked Questions

Why doesn't OneDrive recognize my purchased extra storage?

It can take up to 24-48 hours for newly purchased storage to reflect across all Microsoft servers. Additionally, the local OneDrive desktop client may need to be reset to sync the updated quota from the cloud.

Can I combine Microsoft 365 Family storage with extra purchased storage?

Yes, Microsoft allows Microsoft 365 Family and Personal subscribers to purchase up to an additional 1 TB of OneDrive storage, which is added to your base 1 TB quota per user.

What happens to my files if OneDrive reaches its storage limit?

Once the limit is reached, OneDrive stops syncing new files or uploading changes to existing files. However, your previously synced files remain safe and accessible in the cloud.

How do I force OneDrive to sync after upgrading my storage?

You can pause and resume syncing from the OneDrive system tray icon, or fully close and restart the OneDrive application to force it to check the server for your newly updated storage quota.
