Trouble emailing pay slips?
If you are getting the message "Error sending email" try the following:
Go to Setup > Preferences > Reports & Forms tab and deselect the option to Include all YTD amounts and Entitlement Balances on Paycheques Stubs.
If the error persists, process a "dummy" pay for the employee, then display the pay transaction via the transaction journal and then delete (or Reverse) it. Now try emailing the payslip which was causing the error.
