I recently purchased Copilot for business and they gave me the following email address user+domain.onmicrosoft.com

It is asking me for a code and I cant get it from the authenticator app on my phone but i cant open this because it is asking me for a code on my phone too.

I would lik eto speak to a human as I dont know why they gave me that email address when I already have an email address of [Moderator note: personal info removed]@hotmail.co.uk and want o change the subscription to this address rather to avoid an issues.

Please help.

    Hi @Sean Mienie

    Please note that we are not Microsoft support, and this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, do not have backend access and cannot directly intervene in Microsoft products or features. Our role is limited to providing technical guidance and best practice recommendations based on reported issues, requests, or ideas. 

    I would like to clarify that Copilot for Business subscriptions are intended to be used within a work or business environment. They are not designed for use with personal Microsoft accounts, such as Hotmail.com, Outlook.com, or Live.com accounts. 

    To better understand your situation, may I ask where you purchased the subscription? 

    Was it purchased through a reseller, or directly from Microsoft's official website? 

    If the subscription was purchased through a reseller, I recommend contacting them directly for further assistance with the account, as they may have additional information and support options available. 

    If the subscription was purchased through Microsoft's official website, please contact Microsoft Customer Support for further assistance: Contact Microsoft customer support | Microsoft Support

    I hope this information provides additional clarity.
