I got redirected here from the support form response. See original message below.
Recently, because of a technical error, my work account email@example.com got reset completely (same email but different account/id). I could login via Azure DevOps before, but since the reset I get the following error:
You can’t sign up because login ‘firstname.lastname@example.org’ is already used by an existing user.
Could you delete my existing account so that I can sign up again, or make sure it will connect to the new instance of this account?
