How to structure a report that runs at intervals without multiple files.

Hi /r/PowerShell

Excuse the stupid title, but I’m stuck – Here’s what I’m trying to do:

I have generated a CSV file of all the email addresses on my Exchange server, along with the number of times they have been emailed this week. What I would like is to schedule this script to run once a week, and append the n+1 weeks results as an additional column.

It doesn’t necessarily need to be in CSV format either, so long as I can open a file, and have an idea how many emails are being sent to certain addresses.

Any tips?

Thanks
