Hi Craig,

Prevent duplicates is set to yes but both these users are already in the system with their email addresses the same as those on the CSV file yet one updates and one is flagged as a duplicate.

These users were created when I imported a course with user data. They will then log in via SSO using the associations online authentication. Again same for both users but only one is flagged.

the usernames on the CSV are all email addresses with lower case letters.

Something is amiss. Even a csv that updated yesterday is showing errors today. I'll keep staring at the spreadsheet.

Thanks

James
