Lync 2013 Clients and Lync 2013 server is set up and everything is working. So in this scenario, it seems very odd to get an error like this. However, it will be the case if you happened to have all your users connecting as “external” users. In my example, the 2014 client and server updates to January 2014 are applied. What in the world is this error?
This scenario simply may require the addition of an A record. The internal FQDN the internal Edge server name should be added to your internal DNS. Thank you to Jeff Bender for providing the feedback on this issue. Yes. this is such a small issue, but it obviously says something is wrong. Therefore, don’t forget this DNS record on your deployment, our you may get all the users believing the Lync Server has an issue. This is actually not the case at all. Just another simple DNS issue, that cost 3 hours of my life!
Happy spring 2014 and Lync on America!~ Lync on World!
