External Meetings using Lync Web App vs Lync 2013 Desktop client RRS feed

  • Question

  • We have LYNC Server 2013 deployed on premise. Our clients are LYNC 2013. When someone external to our organization sends us a Lync meeting request we are able to connect with our Lync 2012 desktop client but only Audio is available. We cannot share the desktop. If however we connect to the external meeting using the Lync Web App (by specifying ?sl=1 at the end of the meeting url) we are able to use all the services like audio, desktop sharing etc.

    I've found the following articles that suggest that the desktop clients are not the preferred choice to connect to external meetings.

    http://www.computer-talk.com/en/blog/item/attendees-cannot-join-your-lync-web-conference

    Can anyone advise as to why the desktop clients are restrictive and if there is a fix and if not how can we force users to use the Lync Web App to connect to external meetings?

    Our lync 2013 desktop clients use the following ports:

  • Hi,

    Agree with Anthony.

    The best way to join Lync meeting without federated organization is using Lync Web App as anonymous users. It is easy and it will own all Lync meeting functions during conference.

    If you have done federation with the partner company, then you can both using Lync desktop client and Lync Web App to join Lync meeting hosted by Partner Company successfully with whole functions.

    Best Regards,

  • Do we have federation with this external organisation 

    From my understanding this will not working using your Lync client. The only alternate is to use Lync web app client 

    the desktop clients are not the preferred choice to connect to external meetings.

  • You should be fine using the full Lync client, it's not restricted by default.  If there's an issue, it's typically in the networking related to your edge, or the edge of the organization you're federating with.

    The reason the web client is preferred by many (not all, and that's not an official Microsoft stance), is simply that if everyone uses the web client, it's a consistent experience for the attendees and you don't have to worry about the status of attendee's Lync environment or federation.

    Can your external users share a desktop with internal users?  Can they do it externally in a conference hosted by you?  Can the remote organization share desktops with you when connected to your conferences?  And in these conferences, have the marked you as presenter so you can present your desktop?

    There's no good way to automatically force users to use the web app each time unfortunately.  The other organization would need to hardcode that ?sl=1 into each meeting invite sent.

  • Thanks for the replies. Hi Edwin, we don't have federation with the external organization.

    Hi Anthony to answer your questions:

    Can your external users share a desktop with internal users? Yes

    Can they do it externally in a conference hosted by you? Yes

    Can the remote organization share desktops with you when connected to your conferences? No, in some cases they can't even connect to my conference when they use their Lync desktop client, only the Web App.

    And in these conferences, have the marked you as presenter so you can present your desktop? Yes.

  • I don't believe meetings will work fully without federation.  Can you enable federation or is it off for a reason?

  • Federation is on as we are federated with lync O365 and for push notifications to lync mobile users.

    I can federate with the particular external organization I am currently having issues with and test. But then this means that for every external org that has lync that we want to have an online meeting with I would have to federate. This is not a desirable option and requires more administration.

    I would try the federation and advise. Thanks.
