I have upgraded to Windows 10 and now I find that Lync now longer works. When I start it I get the Lync page and it just keep working and never gets to any usable screen. I try uninstalling it and reinstalling it but still no joy. When I initially open it after reinstalling it I get the message screen that says you need an account to use it but when I click ok it does the same things and just goes into a work state for ever. Goes not even time out. Has anyone else had the same issue?
