how can i gain more points on the ambassador program?

Please keep all Ambassador related questions in Ambassador spaces. You'll want to read the handbook for more information about the program.

For more information regarding the program, you'll want to read the Handbook. There is an Ambassador specific forum you will gain access to and anything Ambassador related should be posted there.

Please keep Ambassador questions to proper channels. You'll want to read the handbook for more information about the program. If you have further questions, you'll want to post in the Ambassador forum (when you gain access) or you can use the Discord server or reach out to Ambassador staff.

Just so you know ranking up on the forum grants you no more rights or privileges than any other user of the forum. You get nothing for your forum level.

If you want to 'rank up' and get something for it then consider joining the Ambassador Program Apply Now. There you can gain rewards such as Microsoft Points
and avatar items for helping people out in the Support sections and over the Ambassador Chat system.

You will have to purchase more MSP, or enroll in the xbox rewards program to gain points over time. There will be no credit to your account. Sorry to have to give you the bad news. You can sign up for the rewards program here :
