Description

Is your request related to a problem? Please describe.
Customers often struggle to understand how exchange services select certificates to initiate TLS communication. This lack of knowledge can lead to email outages shortly after renewing their certificates.

Describe The Request
I have developed a code that enables customers to perform essential checks and identifies necessary adjustments.

Additional context
The script has been tested in the lab environment, which includes the following servers:
4 Mailbox Servers [2 Exchange 2013 / 1 Exchange 2016 / 1 Exchange 2019]
1 Edge Server [Exchange 2019]
2 Domain Controllers
