Description
This policy setting allows you to disable installation of web add-in equivalents of COM add-ins on the switch to new Outlook. The add-ins available for migration are listed in https://aka.ms/newoutlooksettings.

COM add-ins do not work in new Outlook for Windows. By default, users in the organization will get the option to install available web add-ins, in place of COM add-ins, when they move from classic Outlook for Windows.
If you enable this policy setting, users will not get the option to install web add-ins in place of their COM add-ins.
If you disable or do not configure this policy setting, users will get an option to install web add-ins in place of their COM add-ins.
