Allow users to remove themselves from Azure accounts (duh)
I'm an independent contract developer. I did work for a client many years ago during which they added my personal email to their corporate Azure account.
Recently I tried to login again to Azure portal using my personal email and was caught in an infinite redirect loop that timed-out with "your account is locked".
After ~3 weeks dealing with Azure support (who were completely useless) I self-diagnosed that the problem was my email was still attached to the client's account. I asked Azure support to remove the email, but they said I had to contact the client and ask them to remove my email.
In other words, neither myself nor Azure support had the power to remove my own personal email from someone else's corporate Azure account.
That is such a stupid flaw in the user permission and login flow for Azure. I'm very unlikely to ever build on Azure after this experience.
