Have you ever wondered what the distribution of the number of recipients per e-mail in your organization is?
The following script will go through every e-mail received by Exchange and group the results by the number of recipients.
Get-TransportServer | Get-MessageTrackingLog -ResultSize Unlimited -EventID RECEIVE -Start "07/05/2012" | ? {$_.Source -eq "STOREDRIVER"} | Select RecipientCount | Group RecipientCount | Select @{Name="Recipients"; Expression={[Int] $_.Name}}, Count | Sort Recipients
Alternatively, you can group them in batches depending on which format you want the output.
[Int] $1 = $2 = $5 = $10 = $30 = $50 = $75 = $100 = $150 = $200 = $250 = $300 = $350 = $400 = $500 = $600 = $700 = $800 = $900 = $1000 = $3000 = $5000 = $big = 0
Get-TransportServer | Get-MessageTrackingLog -ResultSize Unlimited -EventID RECEIVE -Start “07/05/2012” | ? {$_.Source -eq “STOREDRIVER”} | Select RecipientCount | ForEach {
If ($_.RecipientCount -eq 1) { $1++ }
