Powershell script to report on total send/received e-mails in Exchange

 

Update: 2017-08-16 – I have published a new version of this script here

 

This is a simple PowerShell script that pulls all of the send/received e-mails from the Message Tracking log in Exchange 2010 and counts the unique header IDs.

It’s fairly accurate but I don’t think it’s 100% bang on. My testing showed the numbers generated to be off by about 10%.

This script was built for generic mailboxes but should work on individual mailboxes as well.

 

I have a scheduled task configured on one of our Exchange servers that runs this every Monday morning and provide me the stats on a generic mailbox for the previous week (Monday – Sunday).
