Yes, get an error here. But I have tested some more and I see that it works for another domain that is configured on the same TMG and the same Exchange server. The only difference is the certificate. It seems that there is a connection problem/trust between the two servers regarding the new certificate

Did you move all the certificates to the new box from the old one.<br />
<br />
It could also be something with the certificate. &quot;Test outlook connectivity&quot; should tell you more.<br />

It could also be something with the certificate. "Test outlook connectivity" should tell you more.

Hi all!<br />
<br />
I have replaced the old TMG 2010 server with a new one, and now Activesync doesn't work and OWA asks for credentials twice before letting me in.<br />
<br />
I have checked that there is only basic and windows integrated authentication on the Exchange server, and forms based on the TMG.<br />
<br />
There were some trouble with the certificates, and I had to re-key them, this is maybe some of the problem...<br />
<br />
Thanks!

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
