how to resolve error AADSTS51004

I set up a 1 month trial for MS Project from my home laptop not intending to go thru school account since that FAILED MULTI TIMES!!!!!! Why does it auto link to my SDCCD account instead of using my home account or my new ******@ADVPM285.onmicrosoft.com. This is f*ing time sensitive so I can refresh my Project skill for a job interview Mon 3-25 at 1p PST and I've spent 2 days trying to find my OLD Project account, or school Project account and finally was able to sign up for what ev er the hell this one is. This stinks. Ive been a loyal MS user/client for > 20 years, no and now I'm starting to consider moving to google. ::-(

pozdravljeni!

hello, Katherine,

Thank you in advance for your service.

I signed in to microsoft services some time ago with my personal account and I take use of them only through my personal account also. I was recently informed that it is needed the midterm exams in my university to be taken via ms teams. In order to do that I needed to connect my academic profile to ms services. I tried many times but everytime this result comes out at my screen. I also tried to add my academic account as a guest from my personal account but I can't have access to ms teams from my academic account.

Message: AADSTS50020: User account '******@gmail.com' from identity provider 'live.com' does not exist in tenant 'World Health Organization' and cannot access the application '8523185e-28aa-46c4-a2b2-d467629429f1'(INDICO) 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.
