Azure Portal login account is blocked / How to remove tenants?

Question

Dear community, I've had the following problem for over a year now. I thought, it's about time to clear this up!
So, whenever I try to login to Azure Portal, using my personal account, I always get the "Your account is blocked. We've detected suspicious activity on your account. Sorry, the organization you are trying to access restricts at-risk users. Please contact the admin of Standaardmap,".
Now, the last part of this message is something I can't really place in context. Is it trying to connect to another Azure directory? My account has the 'Visual Studio Dev Essentials' subscription enabled, and should not be part of any Azure directory, other than the one I created a few years ago, using this account. I should be the admin, but I cannot reset or change anything, of what I am aware, to unlock Azure Portal access.
I can login to Microsoft 365, but I cannot login to Entra, Azure or Intune.
If I try to use the Azure benefits from within my.visualstudio.com, eventually I get to see the 'account is blocked' message also.
Things I tried:

• A while back I tried to reset password, mfa and such security measures.
• I also tried the sign-in helper.
• I've tried this page: https://support.microsoft.com/en-us/account-billing/account-has-been-locked-805e8b0d-4141-29b2-7b65-df6ff6c9ce27.
• I've tried this page: https://support.microsoft.com/en-us/account-billing/i-can-t-sign-in-to-my-microsoft-account-475c9b5c-8c25-49f1-9c2d-c64b7072e735.

No results yet.

I did some additional searching. Found out there is this 'Standaardmap' directory (/tenant?) which seems to be causing this. If I login to my.visualstudio.com I see the following data in a dropdown:

• The default selected property is: Microsoft account (marked as blue);
• The 'Default Directory' redirects to the 'Microsoft account' (thus also marked as blue);
• Red arrow indicates the problem directory. It's a Dutch term, which translates to 'Default Directory' :) :)

Regarding the suspicious activity. I might have a clue why it says this: my account has like 10 to 50 failed logins from all over the world. I would still expect to be able to login, using mfa, which has been enabled since like forever.

Does anyone know what to do? Various Microsoft help articles, were not so helpful in my case.

Thanks in advance!

I have found out the following, regarding tenants:

• Default Directory -> Guid: 3ac9f063-9430-4a6a-969b-62e6db5b2ef8 -> Domain: TryAppServiceoutlook.onmicrosoft.com Trying to login at https://myapps.microsoft.com?tenantId=3ac9f063-9430-4a6a-969b-62e6db5b2ef8 results in a 'User does not exist in tenant Default Directory'. How can I leave this tenant?
• <CompanyNameX> -> I can actually fully access this one, on entra.microsoft.com or azure.portal.com Login at 'myapps' works just fine.
• Standaardmap -> Domain -> personalusername.onmicrosoft.com Trying to login at https://myapps.microsoft.com?tenantId=https://myapps.microsoft.com?tenantId={guid_tenant_personal} results in a 'Blocked user, due to suspicious activity'. How to fix this?

I seem unable to leave the first tenant. I remember this tenant from (over 10?) years ago. Other people seem to be having similar issues.

For the third tenant, my personal tenant, I still receive the notorious "Your account is blocked". A password reset, or forgotten password recovery does not solve this. Also, I am the owner, so I cannot contact an admin.

Does anyone have any clue?

Much appreciated after so much time and struggle.

(By the way, I sent an e-mail to a support e-mail account. Somebody responsed and tagged another e-mail account, but they never replied).

If you can login to M365 try: mysignins.microsoft.com Check your MFA and try to reset it if neccessary. Also try: https://myaccount.microsoft.com/organizations and check for your linked organisations, this might help figure out which directory you're supposedly locked out of. From there you can also try "Apps" and see if you can switch to Admin center directly.
