I have an interesting problem to share.
The problem I'm hitting is that I want AAD users to have the domain *@sygmaticlanguage.com, but the problem is that the specific usernames I want to use for AAD users already have MS accounts associated with them because they are real emails (gmail). So I would have to do things like "firstname.lastname@example.org" rather than "email@example.com" because firstname.lastname@example.org already has a Microsoft account, so when the user goes to login to the Azure portal as "email@example.com", they are taken to their personal Azure directory rather than the one I'm trying to set up for them.
How do I work around this? I'd really rather not force my users to use two different logins, especially because the "firstname.lastname@example.org" is already currently being used to work in Azure DevOps, so it would be a big pain to have separate logins for Azure DevOps and the Azure Portal.
