Outlook Add-in for Skype meeting always gets disabled after restarting Outlook 2013

Submitted by Jochus on Thu, 04/01/2018 - 19:49 | Posted in: Windows

To avoid having the Skype Add-in disable after restarting Outlook, I had to execute the following steps:

  • Start Outlook 2013 as an Administrator (this step is important, otherwise, it will NOT work)
  • File > Options > Add-ins
  • Under Manage: Com Add-Ins and click on Go
  • On COM Add-Ins page. Check Skype meeting Add-in for Microsoft Office 2013
  • Click Remove
  • Press OK
  • Close Outlook
  • Start Outlook 2013 as an Administrator
  • File > Options > Add-ins
  • Under Manage: Com Add-Ins and click on Go
  • Press Add...
  • Browse to: C:\Program Files (x86)\Microsoft Office\Office15\UCAddin.dll
  • Press OK
  • Close Outlook and start it as a normal user. The add-in is now activated.

Thanks for the Solution.
For x64 Windows 7, the location is 'C:\Program Files\Microsoft Office 15\root\office15' where UCAddin.dll can be found.

DLL was not in the path you indicated.
I found it in: C:\Program Files (x86)\Microsoft Office\root\Office16

Office 16 folder is for Office 2016
Office 15 folder is for Office 2013

Our IT tried everything yesterday and I chanced upon your page here and sent it to him. We just resolved this by running my account as an administrator and it works beautifully now.

I had to find this file in a different path. It was Programfiles (x86)/microsoftoffice/root/office16. The UCAddin.dll file was here. I had to start outlook as administrator and added the addin with the instructions above using this path. Once added hit ok, closed outlook, reopened as normal and the button was in the meetings section. Hope this helps

You can use the following steps to check the registry: You can visit: " https://www.finetechweb.com/post/skype-meeting-button-always-gets-disab… " for detailed information:

Exit Outlook if it is running.
Press the Windows function key, search for "regedit," and then click OK.
In Registry Editor, locate the following subkey:

In the details pane, double-click LoadBehavior. If the value in the Value data box is not 3, change it to 3 and then click OK.
Exit Registry Editor.
Start Outlook.

Any suggestions if that fails? I'm the support guy and I've fixed that several times for several people, but this one is different. You can check the box and it still doesn't show in the Calendar. You go back and it's unchecked. Still the same after removing it, restarting Outlook and adding it back as administrator again. Luckily, it's Friday. Happy Friday all.
