You can ensure that Online Meeting Add-in for Microsoft Lync 2013 always remains enabled for users by creating a policy that includes it in the Add-in Management List for Outlook. The Add-in Management List policy is included in the Office administrative template files for the Group Policy Management Console. It creates a registry key under HKCU\Software\Policies\Microsoft\Office\15.0\Outlook15\Resiliency\AddinList. You can add a value for the ucaddin.dll to this key, and configure the ucaddin.dll value so that it is always enabled and so that users cannot manually disable it

To Add ucaddin.dll to the Outlook Add-in List

  • To the AddinList registry key, located under HKCU\Software\Policies\Microsoft\Office\15.0\Outlook15\Resiliency\AddinList, add the following value:

    • Registry Type = REG_SZ

    • Name = ucaddin.dll

    • Value = 1 (specifies that the add-in is always enabled and cannot be managed by the end user)
