These are the 2 errors i am getting every time i get a voicemail through Exchange UM.

I am wondering what is going on. Is this an SSL error or what?

i referenced this to try and troubleshoot

i half figured this out... TLS was driving me nuts but is not required with my setup since this is a single server configuration

without TLS the exchange server only sends emails to itself for VoiceMail which is fine for security.
in a multi-server setup i would require TLS

at this point also figuring this out i feel as tho the issue was a Receive Connector that was not setup properly. this receive connector was the connector for my spam firewall but the ip range included the exchange server itself. this connected was not setup for TLS and this is why my SSL certs were not working

have you changed the default certificates that Exchange generated and used commercial one?
