I have a powershell script that runs once per day that generates a csv file with a list of all mailbox users, and calendar access rights for thier mailbox. This csv contains 4 columns
A=Mailbox B=User C=$_.AccessRights D=IsValid
I need another automated script that will run a delta between the previous days csv file and current, and create another csv with the differences between the two csv files, which would then be emailed to specific email addresses.
My 2 big issues/questions are:
-My powershell script creates the same name csv file (export.csv) which ultimately overwrites it, so I would need to either have it save to a different name or prevent the previous day from being overwritten
-Running the delta compare between the csvs and creating a new one
