Hello,

Are you using a work or school email address to send this email? According to the error message, it sounds like that is the case. If so, you need to contact your organization IT admin to check further. Microsoft doesn't manage organization users directly, but each organization manages their own.

Please let me know if that's the case. If not, please provide a bit more information, more context. Such as what type of email address are you using.
