Teamsbot not receiving messages where it's not @mentioned in group chats

Question

Teamsbot not receiving messages where it's not @mentioned in group chats

Kevin Boban 45

I have a Teamsbot that has the following RSCs:
ChannelMessage.Read.Group
ChatMessage.Read.Chat

As per microsoft documentation, these should enable a bot to receive all conversations messages without being @mentioned in channels and chats.

I'm seeing all messages being received from channels.
However, only messages where the bot is @mentioned are being received from group chats.

How do I enable my Teamsbot to start receiving all messages from group chats?

Hi @Kevin Boban

Thank you for posting your question in the Microsoft Q&A forum.

Based on this documentation Channel/Group Conversation Chat Bot - Teams | Microsoft Learn, this behavior is expected:

-Channels:

With ChannelMessage.Read.Group, the bot receives all messages in the channel, even when it is not @mentioned.

-Group chats:

Microsoft Learn documents that ChatMessage.Read.Chat allows access to all chat messages when the app is installed and consented. However, in practice, Microsoft Teams does not consistently deliver all group chat messages to bots in real time. Bots typically receive only messages where they are explicitly @mentioned.

Therefore, your setup is correct, and nothing is misconfigured.

For reference, other users have discussed the same behavior in this discussion azure bot service - Bot does not work with one-to-one chat messages in Microsoft Teams - Stack Over…

@Teddie-D Thanks for the response.
The screenshot you sent says "RSC for all chat messages is available only in public developer preview".
Any plans to release this more widely?

Hi @Kevin Boban
At this time, Microsoft has not shared a timeline for when 'RSC for all chat messages' (ChatMessage.Read.Chat full message delivery in group chats) will move beyond Public Developer Preview and reach general availability across all tenants. While the documentation notes that this capability is available in preview, there has been no confirmation of GA release plans. As a result, bots in production tenants may still only receive messages where they are explicitly @mentioned in group chats, even if the app manifest, RSC permissions, and consent are correctly configured.

Answer 2

To enable your Teamsbot to receive all messages from group chats without being @mentioned, ensure that you have correctly implemented the Resource-specific Consent (RSC) permissions. While you have the necessary permissions (ChannelMessage.Read.Group and ChatMessage.Read.Chat), there are a few important points to consider:

Installation Requirements: The ability for bots to receive all messages in group chats using ChatMessage.Read.Chat is only enabled after a re-installation or new installation into a chat. Make sure that your bot is properly installed in the group chat where you want it to receive all messages.
Testing: If you have made changes to the app's permissions or functionality, you may need to test the app following the steps to upload a custom app in a conversation. This ensures that the new permissions are recognized and applied.
Developer Preview: Note that RSC for all chat messages is available only in the public developer preview. Ensure that your bot is set up in an environment that supports this feature.

If you have followed these steps and the issue persists, you may need to review the bot's installation process or check for any additional settings that might be affecting its ability to receive messages in group chats.
