I am attempting to integrate a Skype for Business Server 2015 (running on Windows Server 2016) with an Exchange Server 2016 (running on Windows Server 2012 R2). I was following the guide here and have been successful in creating the partner applications on both servers. However, when I attempt to test the setup, it fails with the error below:
Which results in the following error:
Test-CsExStorageConnectivity : ExCreateItem exchange operation failed, code=574,
reason=#CTX#{ctx:{traceId:192143289, activityId:"fa709643-3903-49a3-af3e-c8dcff288259"}}
#CTX#StoreException: code=ErrorUnhandledException, reason=Wrapped callback failed --->
System.InvalidOperationException: Client found response content type of '', but expected
'text/xml'.
The request failed with an empty response.
Here's the command I issued on the SfB Server:
Test-CsExStorageConnectivity -SipUri "sip:First.Lastname@mydomain.com" -Verbose
Looks like another user experienced a similar issue on this TechNet thread, but his resolution had to do with a Kemp Load Balancer - which I'm not using. Has anyone run into this problem before and if so, how did you resolve it?
