@Kenn - I have not seen it work. Their reps were extremely unhelpful and I decided to give up on them. I actually fixed most of my problem by using a VBA script in Outlook to move all the attached files into a Dropbox folder, then had an engineer write a Bash script to trim the file names, save as CSV, and move them to my Workbooks folder. I just have to run the script in Terminal and refresh my extracts.
@Brendon thats a good steer. I'll save myself some time - and follow your solution.
So if i understand you right, the first step was setting up analytics report subscriptions with attachments, then pick the steps you describe?
