Hi Pasha,

Greetings.

As you are talking about the topic with the Exchange 2013 on premise environment and are experiencing an issue on it, I kindly suggest you post a new thread on our specific support channel for expert help: office-exchange-server-administration - Microsoft Q&A

Sorry for that our category may have limited resources on checking the issues and questions about on-premise environment.

In addition, you may refer to this official doc. I found: Configure mail flow and client access on Exchange servers | Microsoft Docs

Thanks for your understanding and have a nice day!

Best Regards,

Linda
