New install of Outlook 2016 Click-To-Run for O365. Verified .net 4.72 framework installed. Harmon installs and I can interact with the ribbon buttons to include setting up my site; however, sidebar is blank. The sidebar opens, but it doesn't display anything. Haromon.ie was downloaded just before install - so latest version.
The only thing in the logs that looks related is: com.mainsoft.sharepoint.sidebar.SideBarViewPart - External tabs provider was not found
Any ideas what the issue might be?
