If you are having problems with emailing payslips from TT Payroll using either Microsoft Outlook or your email server, we suggest subscribing to SMTP2GO. 

SMTP2GO is designed for companies that regularly send emails to clients and staff. It quick to setup and will send up to 1000 emails per month for free. Unlike your existing email server, SMTP2GO does not save the email or payslip, so personal information is more secure, helping you meet your GDPR obligations.

You can sign-up and create an account here https://www.smtp2go.com/ then enter your SMTP2GO account details here on the 3rd Party form of the TT Payroll Company screen:
