We are running Octopus Deploy v2019.6.8 LTS and switched from Active Directory authentication to Azure AD authentication this morning. We are cleaning up users which are getting double accounts. During this process we’re changing the display names of users, but when trying to save some users (not all of them) we’re getting the following error message: There was a problem with your request. Your email address is not available.
As the rename works on some users but doesn’t on others we’re not sure on what causes this. Any ideas on what might be the cause?
