I have a scenario where I had configured task reminder action in Nintex workflow to send out three reminders to the users. I tried checking the option of during business only. But this is not working and the reminder mails are being triggered. Please let me know your ideas.
I've had to do something similar....
First of all work out the day of the date.
That gives us the day. From then depending on the result, I can add 24 or 48 hours to get to the Monday and then pause until that new date.
Hope that points you towards a solution.
