The first time an employee logs into SelectHR from Evo, it will match to their relevant person record and update the WorkspaceID field with the workspace user ID.
Going forward, this will be the binding field for that person record, so updates to the email address will update the associated workspace record.
If the employee does not log into SelectHR via Evo to generate this ID before the email address is changed, it will not match, and so it will just create a new Evo user.
You can use the below SQL in Admin Tool to see which one of the employees already have that ID generated:
Select Person.Details.[Person Number], Person.Details.Surname, Person.Details.[First Name], Person.Details.[E-Mail], Person.Details.WorkspaceId From Person.Details
If they have it, then the email can be updated in SelectHR and the integration will be made based on the ID, no duplicate account should be created.
📌 Note: If you want to update the email address for someone that doesn't have an ID generated yet, please make sure they have accessed SelectHR via Evo before making these changes.
