How to fix error 530035 when logging in

Question

I'm trying to log into my client's account in order to connect a third-party domain and set up mail for it. The client himself is not technically savvy, so the task was delegated to me. However, when I try to log into his account, he writes to me that “You do not have access” - strange.

The client's company doesn't have any global administrator or anything like that, and the login I'm trying to log in to is administrator.

Here is the detailed information about the error:
