This Microsoft Dynamics 365 feature requires some Outlook updates. If the necessary updates are not installed, the option to access the Add-ins area will not appear or you encounter the error listed in the "Symptoms" section.

Resolution

The required updates depend on the version of Office you have installed. There is a Windows Installer (MSI) based version of Office and a Click-to-Run (C2R) version of Office.
