Exiting assets (people) are ignored

[Tan-DE]

Since in most cases the field "primary_mail" in the People Asset is empty (in our case at least after an IT GLUE migration), it might be helpful to make the additional field for the email address configurable as a parameter.

Example:
#$HuduUser = $People | where-object { $_.primary_mail -eq $user.UserPrincipalName }
$HuduUser = $People | where-object { ($_.fields.label -eq 'E-Mail') -And ($_.fields.value -eq $user.UserPrincipalName) }

The issue with this is every integration can store the email in a different place. The primary email is what should be set now we can do it via the API.
The other issue would be that, that is the mechanism which contacts created by the integration can then be matched so you would also have to add logic to extend it to adding the email to that filed on creation.
The better solution I can think of would be running a one off script to loop through all the imported assets and just update their primary_mail attribute based off the field that is set.
