I am trying to test a simple integration between Azure Sentinel and Teams. In my current setup I try to use the Post Message connector from Teams - https://docs.microsoft.com/en-us/connectors/teams/#post-a-message-(v3)-(preview). However, when I try to select a team/channel to post my message to I get the following error:
Could not retrieve values. Forbidden. Client request id: '<long ID>'
In Azure Explorer the same Azure account can send message to any Team/Channel I want to. Also after a bit more testing I noticed I get the same error with any other Teams connector.
Any help would be much appreciated.
