I am trying to add a user into our VSTS. This user is a domain account on the company's Azure AD, which is connected to VSTS. The user does not show up in the directory. I imagine they no longer are with the company. However, I am trying to add them so that I can use git-tf to import a repository in TFVC format and use the --keep-author argument.
How can I add this user to VSTS and if I cannot, how should I proceed? I suppose I could create a nondomain email and map this user in the git-tf USERMAP file, but I'm not sure of the best course of action here.
Update: the git-tf mapping is not always working for me. I have added many users from the source repository but only some of them moved to the [mapped] section. Several are still in [unmapped] and one user I cannot add to VSTS because I believe it is a deactivated/deleted Azure AD account, so the add user process fails, saying "Aad guest invitation failed".
Thanks for your help!
