I renewed my UCC SSL on Exchange 2013 server and "cleaned out" what I thought were some old certificates on the ECP admin panel. After that I was able to access the ECP and OWA sites, but when I try to login I get "Something went wrong..." message.
I tried launching the Exchange management shell, but it wasn't able to connect to the server even though I was running it from the same server.
When I go into IIS admin I see the two sites "Default site" and "Exchange backend". I verified both had bindings pointing to my new certificate. I also noticed that there were two certificates named "Microsoft Exchange" and tried using those certs w/o any luck.
Any ideas which cert I need to get this working again or how to recreate?
