Unknown Skype for Business error incur mobile IM history cannot be saved to Exchange
Hi Vincent.
This looks like a problem with server side conversation history not being supported on the branch site deployment. If you move the user to a frontend pool, will the IM history then be written to Exchange Server??
Which CU version are you running on the frontend servers and SBA??

Hi Kenneth,
Thank you for your reply.
My front-end is 2015 RTM and my SBA is 2015 CU3.
According to the CU note, the server-side conversation history is no longer supported on branch site deployment, is it the reason of the mobile issue?
