Verify Account License Status and Backup Your Data

Check your Microsoft 365 account status online and securely back up your OneDrive files to a local drive before the account is fully deactivated.

This issue typically occurs when an organizational or educational license (which often has a fixed validity period, such as four years) expires or is revoked by the administrator.

Sign in to your Microsoft account

Open a web browser and navigate to https://office.com/myaccount. Sign in using the email address and password associated with the Office 365 account that is showing the deactivation warning.

2
Review your subscription status

Navigate to the 'Subscriptions' or 'Organizations' section in your account dashboard to check your current license status and expiration date.

3
Contact your organization administrator

If you are using a school or work account, reach out to your IT administrator or institution immediately to inquire about renewing or extending your authorization.

4
Backup important files locally

Before the specified deactivation date, download all crucial files from your OneDrive directly to your computer's local hard drive or transfer them to a personal cloud storage service to prevent permanent data loss.
