After you install KB3101496 missed phone calls are no longer displayed in Lync 2013/Skype. All other Lync functionality is ok. You will be notified about missed conversation and conversation. The only thing that I have noticed is that missed phone calls are not appearing in the list. After uninstalling this update everything went back to normale.
(UPDATED) After we installed the Latest Lync server 2013 security fix (Security Update for Lync Server 2013 Web Components Server KB3080353) we have had severeal issues where users where unable to sign in to Lync. This was the server complaining about the client certificate , normally it is the client complaining about the server certificate.
Particulary users homed on VDI or Citrix /RDS and also some CommonareaPhones where affected. Inspecting the client log from a user login revealed :
There was an error communicating with the endpoint at ‘https://lyncserver.domain.local/WebTicket/WebTicketService.svc/mex’.
The server returned HTTP status code ‘500 (0x1F
09/18/2015|11:34:46.551 46A8:461C INFO :: CUccPlatform::WriteStreamToLog:
09/18/2015|11:34:46.551 46A8:461C INFO :: 4)’ with text ‘Internal Server Error’.
The server was unable to process the request.
Latest issue was kind of a puzzle. When one organization sent Skype meeting invitation to another organization it was impossible to click on the meeting in the schedule tab of Skype/Lync.
“Join” functionality missing from sceduler tab in Skype or Lync.
Right click on the meeting gave nothing. The links in Outlook and OWA did work thoe. At first we thought it was something wrong with the client installation, but several reinstalls and updates later the conclution was that there had to be something wrong with the calendar entry.
There have been some issues where phone numbers in Outlook does not show in Lync 2013 Client. After some time we discovered that this was because of a Lync/Office update. Yesterday Microsoft releast August update for Lync 2013 Client, this includes a fix for this issue. The updated version is 15.0.4641.1000
