Message: AADSTS50020: User account 'raymond.yun@Stuff .com' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application 'b9c392b1-7049-4d6c-86bf-9bb91214900d'(Microsoft Learning Identity Service) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

I have 2 personal emails and 1 business email that allows for free voucher testing

raymond.yun@Stuff .com which i created in microsoft since something was wrong with my microsoft account. I had multiple accounts that needed to be merged

raymond.yun@Stuff .com
raymond.yun@harsh.com .com
raymond_yun@Zhixin .com

I have so many mcid, i don't know which one to use anymore.
I had one with raymond.yun@harsh.com .com, then I had it merged with my old mcid, which gave me a 3rd mcid. This is getting ridiculous I simply want to schedule the azure and take advantage of the free voucher.
