Thanks for your quick answer.
To be honest with you, I have very little knowledge about Synapse workspaces. When I said I deployed it, it is actually not correct. Someone else deployed it (or tried to) and then left the company.
So really, what I was hoping for was that someone from Microsoft could just log in and wipe the resource group. That is why I entered all the connection details to begin with.
Can you do that or arrange that someone does?
Best regards
