My Microsoft account is not working for Azure

I have a Microsoft account that is recognized by the Azure portal. However, when I try to create a database I get this message:

Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application 'c44b4083-3bb0-49c1-b47d-974e53cbdf3c' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

I don't know what to do to move forward.
