Our business hours are 9am - 5pm Monday to Friday. We have exceptions to this rule, such as holidays etc. but 9am to 5pm covers most. Currently we set our of office manually on a Friday at 5pm and switch this off again on a Monday at 9am. We do the same for holidays.
What's the most efficient way for us to send an automatic email reply when an email is revived outside of these business hours? We would like to automate this as much as possible. So the automatic email replies should go on at 5pm on Friday and off again at 9am on Monday.
I've seen some examples of flows using datetime calculations and others that read from events setup in a calendar.
Any help is appreciated.
