Cannot email payslips

Dear. whom it may concern.

I hope this message finds you well. 

We've tried to email the payslips, but it hasn't been sent through MYOB since last week.

After selecting 'Print/Email Pay Slips' to send payslips, we click 'Send Email' for unprinted or unsent pay slips. Then normally it takes some time to email out all the payslips and we could check the sent emails with attached payslips in Outlook sent box.

However, recently, when we click 'Send Email', the window simply closes without taking any action. And When I checked on the "sent emails" tab, the payslips are not there either as if the program considers them as already sent, We also can't find them in the Outlook sent box.

As we are not able to email payslips through MYOB, we've sent them through online as a temporary solution.(web site's payroll>payruns menu)

But it is way more complicated and takes longer to send all the emails through MYOB online. Is there a way to re-enable MYOB to send payslips as it did before?

* MYOB is still connected to Outlook, and all the settings is the same as before when emailing payslips were available. The emails addresses of employees are also correct.
