Lync Online Meetings Default Browser Woes

When Outlook 2010 and Lync 2010 are installed on the same system users see a “Join Online” button in calendar reminders that allows them to join a conference in Lync immediately. Users can also click the “Join online meeting” link within the meeting invitation and Lync will automatically put them in the meeting.

The way this works for IE is through the use of an ActiveX control which detects whether the full Lync client is installed by detecting the user agent string and if it matches IE, Lync is used to join the conference. For Firefox, there is a Microsoft Lync 2010 Meeting Join plugin which pulls off this detection. If neither method succeeds, the user is directed to the Lync Web App login form.

Joining through either method usually works great, but the caveat is that this only works when the user’s primary browser is Internet Explorer. Let’s face it, IE has come a long way, but many folks (like this guy) prefer Google Chrome or Firefox to be the default browser.

In those cases clicking the button on the reminder, or even just clicking the “Join online meeting” hyperlink within the meeting invite will cause the default browser to open and the user to be presented with Lync Web App. Since IE isn’t being used the ActiveX control can’t load and automatically join using Lync. This is frustrating because the desired action would instead be to use the full Lync client to join the meeting by default.

What I’ve found as a workaround is to use the IE Tab extension within the other browsers to accommodate Lync online meeting joins. These extensions allow you to specify URLs that if accessed through Chrome, should be rendered within IE instead. When you load one of these sites within Chrome it will detect a match and then use the IE engine to display the page. This allows the ActiveX control to detect Lync is installed and properly join the meeting.

As a user you can either define just the online meeting URL used for your organization like* Or, since online meeting URLs defaults will probably be consistent across most Lync deployments you can use some wildcards. I recommend using https://meet.* as the address to automatically open in IE Tab. That way, whether you click a join link for or for you’ll be placed in the meeting with Lync automagically. This allows you to join conferences hosted by federated partners just as easily. Of course, if you visit some other website that matches the meet.* critera it will open in IE, but that’s an annoyance I can live with.

So to get started, install the IE Tab extension for Chrome:

Once installed, click the little IE icon on the toolbar.

Click the second icon from the left, the little funnel (icon choices leave a bit to be desired?), to configure your matching URLs.

In the address section enter your pattern to match such as https://meet.*

Click an online meeting link and you should see Chrome begin to load the page, flip to IE tab mode, and then join the meeting with Lync. The process is slightly slower than if IE is the default browser, but the important part is that it still works.

On a related note, Mr. Elan Shudnow sitting next to me just tested within Firefox and apparently if you’ve also installed the Lync Attendant Console it will open automatically without any of this configuration. Good luck viewing a PowerPoint or Desktop share in that client though!

Hi there. My name is Tom Pacyk and this is my small home on the web. I love the intersection of design, technology, and communication, which is a combination that led me to a career in sales and marketing roles at places like Zoom and ServiceNow. They're a bit old now, but I also had the opportunity to publish a couple of books along the way.

Portland, Oregon is home for me, my wife Beth, and our three kids, but I'm actually a Midwestern transplant—I grew up in the Chicago suburbs and went to school at Purdue and Illinois. When I find some free time I'm probably going to concerts, rooting for the Portland Timbers, or working on my Sunshine Burn Photography project.
