Installed a new SSL Certificate on Exchange Server and now email won't pick up in Service Desk
We updated our SSL Certificate on our Exchange Server (2013) and now we are getting errors in ManageEngine on trying to pick up mail.
I've tried all sorts of things and I'm still stumped.
When I look at the error logs I see that the connection gets dropped during the handshake phase. Everything I'm finding is pointing me towards TLS1.1 vs TLS1.2 and changing those option in Java 7. I've tried that and haven't had a lot of luck getting that working.
Below is a snippet of the error I'm getting when trying to fetch email.
