Launch events not triggering when Outlook add-in is installed from App Source

Jordi Salvat i Alabart 10

Hi.

We developped an add-in for Outlook. It uses OnMessageRecipientsChanged and OnMessageSend LaunchEvents. It was difficult, but eventually we got both events to trigger and operate correctly when installed via sideloading (using https://aka.ms/olksideload), even on Outlook Classic. We submitted it to Microsoft Marketplace via Partner Center, so it is currently published here: https://appsource.microsoft.com/en-us/product/office/wa200006870?tab=overview

But now, when we install our add-in from App Source (by opening Outlook, clicking "Apps" > "Add apps" > searching for "Mixmax" > "Add"), the launch events don't trigger.

Any hints at what might be going on?
