I have noticed that the Microsoft 365 Outlook: Connect action is completely blind - no matter what bogus information I put in for Client and Tenant ID, Username, or Secret, the action states it was successful. This of course, makes using a Try/Catch block useless: a subsequent action will error out but you have to trace it back to the fact the connection was never successfully created.
I am curious, for anyone using this package, what you are doing to error check the initial connection. Or are you just hoping it goes through and moving on with the rest of the bot? I guess I could, as a last resort, add a Check If Folder Exists and look for Inbox directly after the connection, but that seems convoluted.
