iOS9 breaks Lync and S4B meetings URL

iOS9-noOpenmeetingURLThere is one more issue when you upgrade your iPhone or iPad to iOS9: Looks like when try to open a meeting url on Safari (ex: received through a webmail server), the Lync client is not launched and you stay on the meeting webpage (like the picture on the right).

Looking at the behaviour and some initials traces, looks like there’s some update on the Safari web browser that is not allowing the Lync javascript https://<meetingurl>/JavaScript/Launch.js?lcs_w15_onprem5.0.8308.726 from lauching the client.


  • workaround: install/use  the Opera mini web browser on the iPhone/iPad
  • Microsoft confirms the issue on KB3097592 and has another workaround.
  • 25.09.2015 – iOS 9.0.1 update doesn’t resolve the issue
  • 01.10.2015 – Microsoft just released Set2015 CU13 (don’t get confused with Set2015 SU) that contains a web component update to address the issue (web pages and scripts) were updated and safari can now launch the Lync client.
  • 29.10.2015 – After some testings, I noticed that it’s not working for iPad devices with iOS 9.1, released 3 days before which includes 24 security updates (details here)
  • 13.11.2015 – Microsoft confirmed that the iPad 9.x is still not working. Those users still need to use the workaround described on KB3097592 to join meetings urls or my workaround :).
  • 14.01.2016January 2016 cumulative update 5.0.8308.945 for Lync Server 2013 web components server fixes the problem with iOS 9.1 and iOS 9.2

    Agreed, doesn’t have anything to do with the language/region, Lync signs in fine and can IM, just can’t join meetings.

    Microsoft published the solution (server cumulative update). Details on this post.

      Looks like the cumulatie update doesnt resolve the issue. Just tested the cu in our test environment. And the issue is still there.

        Didn’t work on the first for me only after a pool and iphone restart… but I believe you already did that 🙂

      Hi LuisR.
      The CU released is in place, the meeting with an iOS9 user is still not working. The workaround does not help. Any ideea?

    Hello, I did restart all servers in the pool and also the edge servers, even the iphone but still facing the issue that the lync app (sfb) does not get started automatically. Checked also the regional settings and the update is installed on all the servers. Anyone an idea? Thank you!

      “the lync app (sfb) does not get started automatically”
      Does that mean that you clicked on an meeting URL and get stuck, on the initial meeting webpage?

      • NinaM 30/10/2015 / 09:22

        I click on the meeting url, Safari opens – connecting – “already in the meeting? You can install Lync …” message and it does not open the Skype for Business app on the Iphone. (iOS 9.1)

      • Chris 30/10/2015 / 09:25

        Same issue here after applying the CU. Strange enough the iPhone with same ios 9 version works after the CU. So it look likes something related to the ipad only?

      • LuisR 30/10/2015 / 09:37

        Try to uninstall/install the Lync client again (might needed to register the app… I’m not an iOS expert on this 😦 ).
        What I got on the first connection attempt is a prompt to ask permissions for the Safari to launch the Lync client

      • Chris 30/10/2015 / 11:14

        All ready tried uninstalling and installing on IOS but no result. Still a missing link between client and safari. On iPhone indeed first the question access tot appstore and works like a charm

      Hi All,

      For my environment the problem seems to be that the reverse proxy is pointing firstly to Lync 2010 and then to SfB. Found the following article with a workaround that helped in my situation.

      Maybe this is also helpful for you.

      • LuisR 05/11/2015 / 19:34

        That’s the solution/same link that I wrote on the last paragraph of this post…

  4. LuisR 13/11/2015 / 15:22

    Just received an update from MS that for iPad devices the issue is not solved (or reappeared).

  5. LuisR 14/01/2016 / 23:10

    Post updated with MS KB solution
