Email Address Policy

[genkitkl]

I am just wondering if our email address policy is set to "firstname.lastname@domain.com", what happens to those accounts that are without either first or last name? Or accounts with only display name?

For e.g. Peter without lastname will be peter@domain.com? What about those with just display name?

@genkitkl 

in my tests you are correct, an account with peter and no last name but an EAP of first.last will default to peter@contoso.com

as for users with no name, I didn't have a chance to test that out but it may default to userprincipalname.

Do you believe you will have many users being created without name fields entered? input data validation is typically handled by an identity management team and software such as MIM:

have a good day!
