Where do I find the Certificate info for Office 365 that I am using

We use Office 365 exchange, one of our partners is requesting certificate info like,
Who issued the certificate being used
What cipher is being used
What encryption strength is being used by the server

Where do I find that info?

I've gone around in circles looking at articles from Microsoft and not found the answer.  Where do I find that?

Appreciate the help

If they need this information in order to enforce mutual TLS with O365, you will find the relevant details in this article: https://support.office.com/en-us/article/how-exchange-online-uses-tls-to-secure-email-connections-in-office-365-4cde0cda-3430-4dc0-b489-f2c0736c929f

Jem Lian, all ready tried that.  Their response was to read the documents, mentioned by Adam Brown

I've included that document in the response to our business partner, thanks for everyone's help
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
