File transfer and Sharing Desktop Problem

Occasional Visitor

Hi, recently I have Migration from Lync 2013 to Skype for business 2015 , 

every thing is ok and work well , but for client that use Skype for business or Lync 2013 there is problem for send and receive files and desktop sharing ( in Lync 2010 client there is no problem !! ) 

some event show network problem but any port and service is open to client .

is there anyone has similar problem ??

What you can do is check the client logging and see if there is any errors in it.


you can find the log here:

Office 2013: %userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\Tracing

Office 2016: %userprofile%\AppData\Local\Microsoft\Office\16.0\Lync\Tracing

The important file to look at is the Lync-UccApi-#.UccApilog file.  You can open this with the Snooper tool for easy reading and see if there is any errors.
