Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, Evers, Jeroen
This loop usually happens because the personal Office license is tied to a personal Microsoft account, while the computer is now attempting to use a work account. Reinstalling Office will not bypass the personal account verification.
Here are some suggestions you can try:
Open the Microsoft Sign-in Helper in a private browser window. Enter the personal email address originally used to purchase or activate Office, not the work address.
If another verification method appears, select Use a different verification option and try your recovery phone, email, saved recovery code, or another device where you may still be signed in.
If two-step verification is enabled and none of those methods are accessible, the recovery form and support agents cannot bypass it or manually reset the account. This restriction protects the account from unauthorized access.
If Authenticator backup was previously enabled, select Restore from backup or Begin recovery before signing in. The backup must be restored on the same device type, Android to Android or iPhone to iPhone.
After recovering the personal account, sign in at Microsoft account Services & subscriptions and install Office from there. Office must be installed using the account to which the product was originally linked.
The employer’s IT administrator can reset authentication only for the work account, not the separate personal Microsoft account.
Thank you for your patience in reading, I hope this information has been helpful to you.
