Office 365 Support Kunden-FAQ

If you're having trouble logging into your business admin account with the Authenticator App, it might be because of a few reasons. There may be a problem with the app itself, in which case you should try reinstalling it. Alternatively, there could be an issue with your login details. Ensure that you are using the correct username and password. If you're unable to get a code through the app, you can select to receive a code through a text message or a phone call. Remember to keep your security info up to date. If the issue persists, consider resetting your password through the Microsoft portal. Don't forget, Office 365 requires a specific admin username format depending on your organisation's setup.
