We have a new Exchange Server 2013 setup and using activesync. We have setup a policy to require simple password and to send an email to provision a device when it connects. Activesync is setup to use self signed certificates, this was tested first on the Ipad. Certificate installed entered the settings and the device appeared in the quarantined devices list awaiting to be approved. This was also done on the Iphone and worked.
When putting the same certificate on the windows phone device it errored with there is a problem with {as.domain-name.net} and does not appear in quarantined devices screen.
I tested again with another Ipad and an android device and they work without an issue. Tested with a Windows RT device and got the same issue. If I look in the IIS log files I can see the windows device making a connection then when I presume to be the error 500 at the end of the line.
This is not a user issue as I can use the same user on the various devices. The windows devices just do not want to connect. We have looked at the certificate but if it works for apple and android devices why does it not work for windows? Is there any additional security settings that need to be turned on or off for windows phones? Is there something specific on the certificate what windows devices need that others ignore?
