Frequently Asked Questions

How long does it take for the 1 TB OneDrive storage to appear after upgrading?

It usually updates immediately after the payment is processed, but it can take up to 24 to 48 hours in rare cases. You can check your current capacity by going to your OneDrive storage settings.

Do I need to download my files before upgrading to Microsoft 365?

No, there is no need to manually download or back up your files prior to upgrading. The transition happens automatically on Microsoft's servers, and your files remain completely untouched.

What happens to my files if I cancel my Microsoft 365 Personal subscription later?

If you cancel, your storage reverts to the free 5 GB limit. If you have more than 5 GB of data stored at that time, your account will become read-only until you delete enough files to get under the 5 GB limit or purchase more storage.

Can I link my existing OneDrive account to a brand new Microsoft 365 subscription?

Yes, as long as you purchase the Microsoft 365 Personal subscription using the exact same Microsoft account email address, it will automatically link to and expand your existing OneDrive storage.
