This error happens because:
The employee has worked for you before. The original employee record already contains the employee's email address
The email address is being used in another employee record
Using another domain other than GMAIL
You can’t use an email address that’s already been used in Sage Payroll.
If you need to add or recreate a record, create an alias email address within your domain (for example, [email protected]) and use that instead.
Using GMAIL
To work around this, make a small change to the email address used in the new employee record such as inserting a +1 before the @ in the employee email address.
Example:
[email protected] becomes [email protected].
The email address will work the same as the original. The employee doesn't have to change anything with their email settings.
