Unable to create a new Skype meeting from Outlook.

Leave a comment

When trying to create a new Skype meeting from Outlook we get the message “The request failed. Please try again. Make sure that you are signed in to Skype for Business.” skype

First solution was to clear outlook name cache. This solves the problem for a short while.

A better workaround is to disable outlook the use of UCAddin.dll.[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Lync\AddinPreference]
“RecipientResolutionMode”=dword:00000002

Then close and restart Lync/S4B. This is a “bug” in a windows update to the Skype client.

Leave a comment

Lync2013Latest News March 2016: https://support.microsoft.com/en-us/kb/3136400 . This is what we also discovere. But users did not want voicemail.  With the patch from February it seems to be solved.         

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.

LyncCertError

Particulary users homed on VDI or Citrix /RDS and also some CommonareaPhones where affected. Inspecting the client log from a user login revealed :

Unable to join Lync\S4B from client schedule tab.

skypeLatest 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.
