I gather that this can be done but not as simple as inserting a formula. I do not have a clue how to use VBA so I am asking for any help on here.

basically I have a spread sheet in excel 2013 part of the office 365 package that has dates in various cells. I would like an email to be automatically sent out from my outlook to my clients that tells them that something is due next week, something is due this week, and if something is overdue so the client gets 3 email warnings that an event is about to go overdue.

Is this possible?

Ideally I would pass a worksheet over to someone who can do this for me and just tell me how to input my own addresses and edit the different email subjects and body text

Thanks in advance,.
