Can you explain this in more detail? Is it loading Silverlight, or is it
loading a different plugin called Lync Web App? What plugins do you have
listed on chrome://plugins ?

When you say "installed application", do you mean that the old behavior was
that first Chrome opened, and then Chrome immediately opened some
completely different application on your system?

Old behavior: when I would click on a meeting link in outlook, it would
open a new tab in Chrome and somehow "refer" the link to the Lync
application, where everything would proceed (mostly) smoothly.

New behavior: when clicking on the meeting link in outlook, it would again
open the new tab in Chrome, but it would then attempt to load a Microsoft
Lync Web App plugin that would in turn attempt to load Silverlight, which
was not fully functional on Chrome.

I hope that helps.

Please provide the list of plugins you have on the chrome://plugins page
(especially the version of "Lync Web App").

Also, if you could point me to the download page for the Lync Web App
plugin that would be helpful, as I've never heard of it.

I am having the same issue. The lync meeting join plug is installed a
Microsoft's Lync client. You can think of Lync as a corporate version of
MS messenger / Skype. Upshot you probably wont find the plugin on anything
publicly facing. Can i repo and send a log file? Just need to know what
to pull.

Is there a Lync plugin listed on chrome://plugins? If so, when you click on
one of these links do you get a message in your console
(/Utilities/Console.app) that says "PluginMsg_Init returned false" followed
by "Couldn't initialize plug-in"?

The only time I have seen a Lync Meeting URL work within Chrome is to have
the IE Tab plugin (3.9.20.1) installed, as the URL runs an activeX
component.

We started having this issue after upgrading the Mac Chrome browser to
Version 22.0.1229.79. The Lync for Mac 2011 client is version 14.0.2. The
issue did not occur with Mac Chrome Version 21.0.1180.89.

In chrome://plugins/ it lists:
Lync Meeting Join Plug-in
Microsoft Lync 2010 Meeting Join Plug-in
--no version is listed

In Mac console:

Okay, thanks; that's what I needed.

The reason this started with Chrome 22 is that we dropped support for
legacy graphics and event models (QuickDraw and Carbon, respectively) that
have been deprecated for several years. To remain compatible with Mac
Chrome 22+, plugins need to negotiate the new CoreGraphics and Cocoa
models. Almost all the popular plugins have updated over the last several
years, and I had reached out to the vendors of plugins I was aware to let
them know. I hadn't heard of this plugin, so I hadn't contacted them.

The fix here is for them to release an updated version of their plugin. If
their plugin doesn't draw or handle events (and it sounds like it doesn't,
but is just a bridge to the app) then adding the negotiation to the plugin
is a trivial change in their plugin.

I don't see any contact info for them, so what would help is for anyone
experiencing this to contact Microsoft Lync technical support or any other
contact point you have to let them know that their plugin needs to be
updated, and point them to this bug for details. Feel free to provide them
my email address in case they want to follow up in any way.

Is there any work around to be able to put this lync capability back,
whilst microsoft look to see what update they can do to the client. Can we
back out the Chrome Update?

We have no plan to re-add Chrome support for long-deprecated NPAPI models,
no.

Thanks Stuart, Understand the standpoint.
I've noticed that Cisco Webex plugin also broke at the same time with this
chrome update - but luckily they have provided a hotfix manual to overcome
the problem. The question i have is, is there any way to get back to the
previous version of the browser before this NPAPI model support was
withdrawn?

Given chrome did an auto-update its broke two key plugins i use - which i
didn't realise until i tried to use them - giving a poor customer
experience, i would like to 'revert' back to the previous version if
possible.

Older versions generally contain known security vulnerabilities, so we
strongly discourage doing that. If you really want to go that route despite
it being dangerous, I imagine you could find instruction somewhere on the
web, but there is no supported/official way to downgrade.

> luckily [WebEx] provided a hotfix manual to overcome the problem

More specifically, they made exactly the same change Microsoft Lync needs
to make, and made that updated plugin available quickly. I'd encourage you
to try to convince Microsoft to do the same.

I open a SEV B with MS (112100375636926) and had a conversation with our
TAM and the net net is that "yes, it doesnt work. We are not going to
address it because there are higher priorities .. downgrade your browser or
use one of the supported ones."

It's unfortunate that they are unwilling to make a trivial change (I'd be
happy to send them the handful of lines of code they need to add if that
would help) to support their enterprise customers. I'll leave this open as
ExternalDependency in case they change their mind, and I'd suggest everyone
experiencing this to report it in the hopes that might shift their
priorities.

The fact that they recommend exposing yourself to security vulnerabilities
to work around their lack of update is even more unfortunate. Again, I
recommend very strongly against that; copying the link to another browser
when you need to use Lync would be a much better work-around.

(On the Chrome side, presumably this will be fixed once we have a 64-bit
build--64-bit Firefox and Safari don't support QuickDraw+Carbon either, and
it sounds like the plugin works there, so they are almost certainly
shipping a 64-bit binary too--but that's a substantial undertaking, and
there's no specific timeline on it.)

You'll have to either pass that along to Microsoft, or wait for a 64-bit
version of Chrome; see the discussion above.

(In the future, please just star bugs to indicate interest in seeing them
fixed.)

This is just a quick comment to any that are researching this issue. Our
company still uses IE8 as the standard company browser (to ensure
compatibility with existing websites and web apps.) They have no problem
installing other browsers.

I use Chrome as my default browser and I am experiencing the same MS Lync
problems as described above. However when I make IE my default browser, and
then click the link provided in a meeting invite, it opens a new tab in IE
and then does something with Lync directly to connect me to the meeting.
That's my work-around solution - make IE your default browser when you need
to connect to a meeting. Fortunately I have only a one or two meetings per
week I must attend.

Our company is a premier partner with Microsoft. (We own Avanade.)
Unfortunately I have no idea how to communicate with Avanade and request
this be made a higher priority.

This is a Mac-specific bug related to completely Mac-specific specifics of
the Lync NPAPI plugin and Mac Chrome's NPAPI hosting code; given that you
are discussing IE 8 I'm guessing you have some completely different issue
on Windows (with similar symptoms), in which case you should file a new bug.

Similar issue here, 64bit Chrome - latest v38 - 10.9.5 Mac OS X everything
client side fully patched with exception of Mac OS X 10.10 (released last
week, waiting for the worst issues to be found by others).

I see "Microsoft Lync Web App Plug-in 15.8.0.0" in chrome://plugins

When visiting the meeting page I am always prompted to download the meeting
client, or I can untick and use the web version.

My colleague reports same Chrome, same Mac OS X and no issue, but he had
upgraded from a previous version of the plugin, rather than 15.8.0.0 being
first client version. Aside from upgrade versus new we are not aware of any
other differences, but clearly there is something different.

Nothing is logged to Mac OS log files with the word Lync in when the
problem occurs.

In the browser console I see:
TL_ERROR, , Framework, CheckExistence of plugin object __versionChecker_1
failed. Exception : undefined is not a function,
Lync_Client_PluginFramework_PluginObject$$10_1, ... stack trace follows ...

This is when loading the first page, which presumably is loading the plugin
version to decide if it should offer me the download.

For some reason I also see an unresolvable hostname for the Volume control
PNG (error by deployer?) web server, but guessing that is unrelated error
in customisation of UI or some such.

If I tick "Allow Always" in the chrome://plugins page for the Lync plugin,
I can proceed without downloading the application again.

With "Allow Always" the error disappears and it is able to retrieve plugin
version information correctly, and displays the page without the prompt to
download.

Indeed the remaining errors are one parsing the meta tag "viewport"
where "user-scalable=0;" is flagged as requiring a ",", I'm guessing this
is just it should be "yes" or "no" rather than "0", and so it is parsing it
wrongly, and one about not being able to resolve the hostname for the
volume control.

I have plugins set to "Click to Play" rather than Chrome recommended
settings, changing this (without restarting browser) doesn't change the
behaviour.

So not sure from above whether this is a plug-in issue or a client
configuration issue, but should be a good pointer for both users, and devs
to understand what is happening here. Happy to look further but we are
occasional Lync users and much prefer people to use services which don't
require browser plugins.

Meantime I'll disable this plugin when not actively trying to join such a
meeting.

Still not working, everytime I click on a Lync Meeting link in Outlook
2011, it loads Chrome, and goes for the Lync Web Client. Tried it with both
the Chrome Lync plugin and without. No luck.
Used to be able to select the option to open the meeting with local Lync
client, from the resulting webpage after clicking the link in outlook. Now
that option has dissapeared.

As a workaround, I have to currently click the link in Outlook, wait for
Chrome to open and then copy the link out of chrome, and paste it into
Safari. Safari then properly offers the option to start the meeting using
the local Lync client. Far from ideal, but gets it working...for now...

Can we get this fixed please? Else I will be forced to remove Chrome. As
I'm sure will many other users facing this issue. 2012 this issue was
raised, thats a surprise...
