Cannot log in MS

The error message you are encountering, AADSTS50020: User account '******@hotmail.com' from identity provider 'live.com' does not exist in tenant 'Microsoft', indicates that the account you are trying to use does not have access to the specified application in the Microsoft tenant. This typically happens when the account is not recognized in the tenant you are trying to access.

To resolve this issue, you need to ensure that the account is added as an external user in the tenant. Here are the steps you can take:

1. Sign Out: Log out of your current account.
2. Sign In with a Different Account: If you have another Azure Active Directory user account, try signing in with that.
3. Add as External User: If you need to use the hotmail.com account, the administrator of the tenant must add it as a guest user in the Azure Active Directory.

Once the account is added, you should be able to access the application without issues.

Hello

What is the context here?

Based on the error message, all I can tell is that you are using a personal account to access somewhere that's for business/school users only.

So I need to know, where exactly are you logging in? For example, what app, what website, or what settings page?
