在Azure AD b2c中创建新用户错误:属性proxyAddresses具有相同值的另一个对象已经存在

Question

我有一个程序，我通过微软图形在我的Azure AD b2c中创建用户对于普通用户，代码运行并创建AD b2c帐户

在B2C中，我有管理员用户，它们是租户管理员当我尝试以编程方式创建与b2c用户相同的用户帐户时，我得到错误

Creating new user in Azure AD b2c error: Another object with the same value for property proxyAddresses already exists

但是当我通过GUI执行相同的操作时，我可以添加2个具有相同电子邮件的帐户。第一个是作为admin被邀请的用户，第二个是B2C普通用户

var user = new User
{
AccountEnabled = true,
GivenName = "MJX",
Surname = MJX,
Mail = theEmail,
DisplayName = "Someting",
UserType = "Member",
CreationType = "LocalAccount",
PasswordProfile = new PasswordProfile
{
ForceChangePasswordNextSignIn = true,
Password = GeneratedPassword,
},
PasswordPolicies = "DisablePasswordExpiration",
Identities = new List<ObjectIdentity>
{
new ObjectIdentity()
{
SignInType = "emailAddress",
Issuer = tenantName,
IssuerAssignedId = theEmail
}
}
};
//insert into AD
var createdUser = graphServiceClient.Users
.Request()
.AddAsync(user).GetAwaiter().GetResult();

Answer 1

删除了Mail属性，它为我工作

//Mail = theEmail
