Failed to login SpecFlow+LivingDoc in AzDo using SSO

Hello,

I'm experiencing issues with the account I'm using at the clients office. When I try to open SpecFlow+LivingDoc I have to create an account. The I got an error message that an account already exists. I think that the account should be deleted. 

I already send a request to info@specflow.org (email from the account itself), but did not receive an answer to that.

Best regards

Antoine
