How to log in from a second account in Outlook?

Question

SMTP

I go to the admin panel of the next domain admin.google.com , I have several accounts with one mail server, let's denote it as [email protected] , for example: [email protected] , [email protected] , [email protected]
I go to one of them using Outlook , for example admin, set the
login setting manually: [email protected]
password: 123
From the bottom, I select the following settings for the server of outgoing and incoming mail:



Authorized, everything is fine. I'm leaving.
I'm trying to connect with the same settings, but with a different name [email protected] - it won't let me ones , what could be the reason?
