Bug with Activator Teams bot

Hi tayloramy,

Thank you for contacting the Microsoft Fabric Community Forum.

Based on my understanding, the message "You cannot send messages to this bot" in the Fabric Activator Teams bot might occur due to:

1. The bot or app is blocked for the user or tenant in the Teams Admin Center.
2. The bot was previously blocked by the user.
3. A Teams client issue, particularly in the New Teams client, causing the chat input box to be disabled even though the “Message Fabric Activator” remains active.

Please follow the steps below, which may help resolve the issue:

1. Sign out of Teams and sign back in, then try again using the Teams web app (https://teams.microsoft.com).
2. Check with your Teams administrator to confirm the app is not blocked by navigating to:
   Teams Admin Center → Teams apps → Manage apps → Fabric Activator (should be Allowed), and
   Teams apps → Permission policies / Setup policies.

Additionally, please refer to the links provided below:

We hope the information above helps resolve the issue. If you have any further queries, please feel free to contact the Microsoft Fabric community.

Thank you.
