I've built an integration with MSFT Teams that works from a service catalog item. We have a sandbox instance of O365 that I used to do my testing. Everything works fine in that environment.
Now that we're getting ready to implement, I need to connect to our production instance and that's where the trouble starts. We've converted the OAUTH Application, credentials, etc. to be pointing to the production instance (tenant id, client id and client secret). The problem is that when I try to get a token, from the REST message or the credentials, I get the error shown in the attached MSFTError.png. Can anyone translate what the message is telling me and how I get past that?
All answers are gratefully appreciated.
