Frequently Asked Questions

Why did my eBay Office 2019 purchase come with a work or school account?

Some unauthorized third-party sellers bypass consumer licensing by selling volume-licensed organizational accounts instead of legitimate individual redemption codes. This improperly links your installation to an unknown organization.

Will disconnecting the work account delete my local files?

Disconnecting the account from Windows will only remove the organization's access and administrative policies from your device. Your locally saved documents will remain intact, but any files saved exclusively to that account's OneDrive will be inaccessible.

Can I just delete the unauthorized Microsoft account entirely?

It is highly recommended not to delete the entire account right away. First, verify whether it is an account or a redemption code, and ensure it is not inadvertently tied to any of your personal data or other subscriptions.
