microsoftTeams.people.selectPeople search service sometimes not returning an email attribute for users

[LeonYasoon]

Continuation of #1526

When using the microsoftTeams.people.selectPeople chooser in a MS Teams App context like this:

Unfortunately, when a user object returned by the searchV2 endpoint used by the peoplePicker doesn't have an email attribute, the people picker returns that user with an empty string as it's email as you can see here:
Search for users in peoplePicker and observe searchV2 response:

Confirm peoplePicker selection and console.log the return result.

Is the email not being in the searchV2 response a bug or is this something users or Azure AD admins can configure?
Would it be possible for the peoplePicker to always return email and UPN so clients can handle these cases at their will?
