I had an issue with my email as well, although I am not sure if it is the same as yours. I would browse to my work's site to get certs, download them and click to install from IE as I had done in the past. I got a message stating one or more certs installed, as expected, but then when the synch would run, it would not complete and there was an error message stating my certs were invalid. After trying it over and over again, I finally went to file explorer and ran the certs from there, which gave me the message where you choose to block or get more info and THEN said it installed one or more certs. After this it worked. It was like the install never actually worked when attempting it from IE directly. Sorry if this is a long winded explanation or if this is something people were already aware of.
