Problem
When creating a new user, the system flags the email or username as already in use.
Cause
The email or username is already linked to an account in the Atlas platform — not necessarily within your organisation.
Fix
For administrators
If the email is already in use:
Ask the user whether they've previously used this email with any iHasco product or another Atlas company.
If they have, ask them to update their email on that other account, then try again.
If the conflict is within your own organisation, archive the old user first.
If the username is already in use, create a unique one — for example, add a number or department code (such as jsmith2).
