Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Adrien,
May I ask what is the type of the token and detailed subscription plan (If it's Office 365)? Please check the following article about activating Office: https://support.office.com/en-us/article/Activate-Office-365-Office-2016-or-Office-2013-5bd38f38-db92-448b-a982-ad170b1e187e
And you may provide the detailed error or notification which refused your token in a screenshot so we can further check it for you.( Remember to remove your private information on it to protect your privacy)
In the meanwhile, you may also contact the third party who provided the token to you which can be more efficient in this scenario.
Regards,
Leo
