2 weeks ago, I mentioned a training session I gave for a client. They had me back for another session late last week, this one focused on conferencing.
All went smoothly at first. People were able to join a Lync Online Meeting I set up, enable video, talk to each other…
…Except for one person.
When she tried to join the meeting via her Outlook invitation, she received a DNS lookup error. Each time. Naturally I went to her computer to see what the problem was.
Turns out the problem wasn’t with Lync.
It was with Google Chrome.
Chrome Browser And Lync Helper Don’t Speak to One Another
What had happened? Well, this particular person had Google Chrome set as her default browser. Now, that’s not a bad decision. I like Chrome myself; it’s great for testing, and works very fast.
However, the Lync Browser Helper is not configured to play nice with Chrome. And Chrome doesn’t like it anyway.
The Browser Helper add-in connects Lync Online Meeting commands with the Lync client on your computer. For example, when I joined the meeting (though I was only a federated partner & not part of their Lync Server network), my Lync Attendee client opened up. Lync 2010 or Lync Attendee opened for all the others. This is because the Browser Helper auto-loaded once the Outlook meeting link was clicked, and called up Lync.
But when the Chrome user clicked the meeting link in Outlook, Browser Helper didn’t recognize it. The command failed, and she ended up with a DNS lookup error.
At first I thought there was a missing DNS setting in the external certificates. But according to this Microsoft Support page:
External users can’t join Lync Online conferences anonymously or as guests – Microsoft Support
“The user is using Google Chrome as their default browser. The Lync Browser Helper add-in isn’t configured for Google Chrome when the Lync 2010 Attendee client is installed.”
And this discussion:
Starting Lync Meeting with Google Chrome as default browser – Office 364 Community
“Chrome does not like to interact with other programs. So when you attempt to join a meeting with the Join Meeting link, it loads an aspx which attempts to search for the client outside of the browser. Since the aspx runs into this roadblock it fails the search and falls back to the webapp.”
Clearly I’m not the only one who’s encountered the issue!
Want to Run Lync Online Meetings? Use IE
The solution to this little conundrum is simple. We switched the Chrome user’s default browser to Internet Explorer, clicked the Online Meeting link again…and she connected in a flash.
That’s all you need to do. Set Internet Explorer as your default browser before you run a meeting. (You can even switch it back afterward!)
To set IE 10 as default in Windows 8, go here: Make Internet Explorer you default browser – Microsoft Windows 8 Support
For IE 9, click the Settings icon at top right (the gear). Click “Internet Options.” In the Settings window, click the “Programs” tab. At the top you’ll see the “Default web browser” field. Click the Make Default button. Then click OK. You’re done.
And with that, The Lync Insider is off for the holidays. We at PlanetMagpie hope all of you enjoy your Christmas, and we’ll see you all in 2013!
