The backend has two connection and looks as if the internet connection is not disabled then ActiveSync still works, if the internet connection is disabled then it stops working. ARR server is step up to only use TLS 1.1, TLS 1.2, backend is setup to use TLS 1.0 and SSL 3.0 which is the limit of 2008. Please note ARR server is Windows 2012 R2 back end is 2008. I have remove compressing and increas e buffer size. This could have occurred as a result of a network error or because of a problem with the certificate installation. The certificate couldn't be validated because SSL negotiation wasn't successful. Join your peers on the Internets largest technical computer professional community.

The Microsoft Connectivity Analyzer wasn't able to obtain the remote SSL certificate. Obtain the SSL certificate from remote server on port 443. The Microsoft Connectivity Analyzer is attempting to If I try and test from Microsoft Activesync tester I can SSL handshake aborted SSL=0x7970dac0, I/O error during system call. It looks to be a certificate problem but the certificate works for OWA. No matter what I try I cannot get it to work.

The problem I am having is with Activesync. The Internal Websites is working fine and Exchange OWA is working without a problem.

I have just setup a new ARR server for two websites, internal and exchange. Hope someone can help me with this, its driving me crazy.
