OutlookStatView scans your Outlook mailbox and displays statistics about the users you communicate with. These insights can show who you spend the most time on, what times they are active, or if they are taking up a lot of inbox space.
Details for each user/email include the number of outgoing messages that you sent (separated by to/cc/bcc), the number of incoming messages, the total message size, and the client software. It also provides a time range that you send/received emails were sent or received.
A 64-bit version (only for use with Outlook 2010 64-bit) is available.
