Bot not receiving message events in shared channels (RSC)

Hi folks,

Running into an issue with a bot in Microsoft Teams shared channels.

I've configured RSC permissions to listen for new messages. This works as expected in standard channels - I receive events for every new message.

However, in shared channels, the behavior is different:

  • I only receive events when the bot is explicitly tagged
  • Regular messages in the channel don’t trigger any events

Permissions currently granted:

  • Channel.ReadBasic.All (Application)
  • ChannelMember.Read.All (Application)
  • ChannelMessage.Read.All (Application)

Has anyone faced this with shared channels? Is this expected behavior or am I missing something in setup?

Thanks!

  • Deepak, to make the app work in shared channels, you need to do the following:
    1. Update the manifest to declare support for shared channels. Instructions can be found here:

    2. Enable the app in the shared channel once the app has been installed in the parent team.
