I am having issues with my Microsoft365 license activating. It seems to be getting stuck over and over in the authentication step. I have tried clearing keychain, library, restarting, etc. I am on a MAC. the admin has also removed and re-added my license and that didnt help either.

    Hi Kaila,

    Based on your description, the issue seems to occur while the account is being authenticated, rather than when the license is being validated. Since your administrator has already removed and re-assigned the license without any change, you may want to ask them to reset your MFA methods and re-register MFA for the account.

    If there is a problem with the existing authentication registration, re-registering MFA can often help resolve sign-in and activation issues.

    After the reset, sign in again and complete the MFA registration process before attempting Office activation.

    I hope this information is helpful. Let me know if you have any questions.
