REST API Method: POST /rest/asmlyncevent?action=exportlog
This resource exports all the Lync Log events from the ASM. This action is applied without an ID.
The downloaded filename is 'Lync Server Events.evtx' as displayed in the response header.
The filename should be saved with a .evtx file extension so it can be viewed with the Microsoft Event viewer.
If the file is too big, it will be chunked into 4KB chunks and sent to the client.
