Unable to login to Lync on a off-domain computer, getting some kind of certificate error.
I think setting up outlook fixes the issue because this install the required certificates from the domain CA server. Can we not instead just install the certificates? Usually you can visit http://%nameofmyCAserver%/certsrv to install certificates? These are installed automatically on domain machines but not non-domain machines over VPN. I think that’s the issue here.
