active sync

Not open for further replies.


I am not able to integrate my devices with active, i get an error :

Unable to open connection to server due to security error ..


Can you tell us a few things:
What version of Exchange are you running? What is the architecture (# CAS, load balancing, reverse proxy, etc)? What types of devices have you tried?

Also can you go here and test and then post the log:


Besides the troubleshooting steps from Tim, please also try to steps below:

Please check if there"s any error event in the application log on the CAS server after reproduced the issue

Please check if there"s any related trace in the IIS log on the CAS server after reproduced the issue

Could the issue be reproduced on other devices with same user configuration? Please see if you can reproduce the issue with windows mobile emulator
