Thank you Diane!
Yes. Every attachment's name goes like Report_YYYYMMDD.csv For example, today's report is like Report_20140915.csv
And a important information may be that it seems all the script rules won't apply now...I did some simple tests on it. All the rules requires a script won't do...
I am working on a script that enables Outlook to automatically saves attachments.
Here's my codes:
Public Sub SaveAttach(Item As Outlook.MailItem)
RootPath = "D:\Monthly Update Report\Generate Sum Rep\"
SaveAttachment Item, RootPath, "*.*"
