Is it possible for me to rejoin the Xbox ambassadors program.

If you were removed for an enforcement action and were able to submit a case review and the suspension was overturned, you would need to email xboxambs @ microsoft.com (remove the spaces) to contact Ambassador staff to rejoin. If you were not eligible for a review or the enforcement team denied the appeal, you would not be eligible to rejoin.

You would need to email the ambassador's inbox.

Hi, I'm Miguel, community expert, I may not be an employee of Xbox, but I see you need some help, I'm Happy to help you.

Typically if you're banned from the program it is permanent. However, if you were removed due to an enforcement action, and the enforcement team overturned their decision after you submitted a case review, you can contact Ambassador staff to be added back. You can email xboxambs @ microsoft.com (remove the spaces) to contact staff.

Unfortunately if you receive a suspension as an Ambassador you are banned from the program. Since it's not possible to submit a case review, there would be no way for you to rejoin the program at this time.

Sorry, but one of the requirements for the ambassador program is that you have no enforcement actions on your account history. There is no way around that.
