Hi,
looks like I did everything to integrate Exchange 2016 and Microsoft 365.
1. All Virtual directory URLs are available from internet
https://ex01..com.ua/ecp , https://ex01..com.ua/owa, https://autodiscover.***.com.ua/ ... powershell
2. The certificate has been assigned
I`m getting error
ex01.***.com.ua refused to connect.


Please, help me to resolve this issue.
Thank you.
