We have a use case where a customer can have SSO set up with our app and their IDP, and users will log into our app via SSO (never providing any information directly to our app). We don't get an email address for the user, and for some PII concerned customers, don't get any PII at all. Since Okta appears to require an email for each user, what is the best practice for "assembling" an email address that is unique to each user? We can imagine lots of ways, curious to hear others approaches (if you've encountered this)?

You can use Okta username. Thats very straight fwd. If that does not work, you can have a employeeID some thing like that as Unique Identifier and pass the same in SAML response. Btw can you confirm Okta is IDP & your app is SP ?
