How to investigate Teams errors or analyse the log file

[Thomsch]

From time to time errors happen within Teams. One current example of that is that users cannot create a new planner plan and add it as a tab within Teams.

There is just this error message "Failed to create the plan" but no hint where to look. Is there any place within the logs I could take a look for errors like these?

I have seen this error before and the solution that might seem odd is to be sure you are also a member of the Group/Team you are going to add the Planner Plan. By the way, there is not a place to get info. about errors like this one not so related to Teams but how Planner Plans are created
