When you try to access an InfoPath Forms folder in your mailbox in Microsoft Outlook 2016, you receive the following error message in Outlook 2016:
Cannot display the folder. An OLE registration error occurred. The program is not correctly installed. Run Setup again for the program.
If you have a programmatic solution that uses the Outlook Object Model to access the InfoPath Forms folder, you receive the following Microsoft Visual Basic run-time error message:
Run-time error '-2147221164 (80040154)': An OLE registration error occurred. The problem is not correctly installed. Run Setup again for the program.
Office 2016 does not include InfoPath desktop client. InfoPath 2013 is the last release of the desktop client.
If you are not actively using InfoPath forms in Outlook, you can prevent the errors in the Symptoms section by deleting the InfoPath Forms folder from the Outlook folder list. Before deleting the folder, use an earlier version of Outlook to view and back up the contents.
