Exchange 2013 cu21
i don't have a lot of experience working with ssl certificates with Exchange 2013. from what i can gather, i just generate a CSR, submit it to a CA, and i'll get back a renewed certificate good for another year or so.
i did just that, got the .CER and completed the request from ECP. but this morning, a lot of my users (who don't have Internet access) are complaing they are receiving below message when opening their Outlook.
i have also assigned the services required to this new certificate
how do you resolve such problem?
