Hi Guys,

Hope someone can help me with this, its driving me crazy.

i have just setup a new ARR server for two websites, internal and exchange.

The Internal Websites is working fine and Exchange OWA is working without a problem.

The problem I am having is with Activesync. No matter what I try I cannot get it to work. 

It looks to be a certificate problem but the certificate works for OWA. 

If I try and connect with Touchdown. 

Server Cert not trusted

SSL handshake aborted SSL=0x7970dac0, I/O error during system call. 

If I try and test from Microsoft Activesync tester I can

  

The Microsoft Connectivity Analyzer is attempting to

obtain the SSL certificate from remote server mail.transamerica.com.au on port 443.
 The Microsoft Connectivity Analyzer wasn't able to obtain the remote SSL certificate.

Additional Details

The certificate couldn't be validated because SSL negotiation wasn't successful. This could have occurred as a result of a network error or because of a problem with the certificate installation.

I have remove compressing and increase buffer size. 

Check and double checked URL Rewrite.

Please note ARR server is Windows 2012 R2 back end is 2008. 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. 

Thanks for your help.

Questions about IIS are best asked in technical forums with IIS experts.  iis.net/forums

Hi

I am not sure if this is an IIS question or an ARR question. It is my understanding that ARR is look after by the Windows Server Team.

Its full name is IIS ARR - http://www.iis.net/downloads/microsoft/application-request-routing  This is definitely an IIS technology.  It never comes into play in Windows unless IIS is being used.

Hi,

Ok will look at moving to the IIS Forum, but I did read ARR was looked after by the Server team and did find this forum by searching ARR in forum.

Thanks.

Yes, IIS is also 'looked after' by the Server team. However, IIS has a community that has built up around it. There are also separate forums for Remote Desktop Services, Active Directory, Hyper-V, Security, and many others.  All these are 'looked after' by the Server team, but if you want experts who focus on those particular technologies, you will find more experts by posting to those communities.

You've done nothing 'wrong' by posting here.  I'm just trying to direct you to a location where you are likely to find more knowledgeable p
