Hello,
A client would like us to send TLS encrypted emails to them. We have an exchange 2013 server that has been in operation about 1 year. I admit I know nothing about what is involved with TLS.
Do we need an additional certificate or multiple certs for each sender?
Where do we install it? Is it strictly in outlook and not in exchange or is there an option to have it on one or the other?
Any soup to nuts articles that get into the details on how to set it up (not the theory that doesn't tell me any powershell commands or stuff like that?)
