Why do I see the error ‘The bot was blocked by a permission policy’ when trying to send ChatOps messages in Teams?
Description of issue
If you see the message “The bot was blocked by a permission policy” in the Push admin console when trying to send ChatOps messages in Microsoft Teams, you will need to update your third-party apps policy.
If you block third-party apps in Teams, you may encounter this issue, even if you successfully completed the Teams integration with Push.
Resolution
Update your Teams permissions to allow Push as a trusted third-party app.
Select the appropriate policy.
Under Third-party apps, search for and add Push Security as a trusted app.

It may take a few minutes for the new permissions to take effect. You can then retry sending ChatOps messages.
