We have two domains. abc.com and 123.com. Each user has two email addresses. john.doe@abc.com and john.doe@123.com. The abc.com address is the primary address. Customers and vendors have been requested to use the abc.com address. I would like to track the number of messages received, by day, by user for the older (123.com) addresses. I'm trying to determine the consequences of removing the 123.com addresses. Does anyone have a script or application that would provide the requested data?

Get-ExchangeServer | where {$_.isHubTransportServer -eq $true -or $_.isMailboxServer -eq $true} | Get-MessageTrackingLog -sender "xxx@123.com" -Start “04/01/2011 12:00AM” -End “04/04/2011 5:00PM” | Select-object Sender,Recipients,RecipientCount,MessageSubject,Timestamp,EventID,Source,ClientHostName,ServerHostName,MessageInfo |sort-object -property Timestamp | out-Html | out-IE Out-IE and Out-HTML can be downloaded from vivek sharma's blog

Mesage Tracking would certainly give you an idea and woud cost nothing. You havent said what version of Exchange you are using, but in 2007/2010, built-in: Advanced Exchange 2007 Transport Logs Troubleshooting using Log Parser - Part 1 http://msexchangeteam.com/archive/2007/11/12/447515.aspx Advanced Exchange 2007 Transport Logs Troubleshooting using Log Parser - Part 2 http://msexchangeteam.com/archive/2007/11/28/447598.aspx 3rd party: Message Stats - http://www.quest.com/messagestats/

Hi, Which version of Exchange is installed on the machine? If it is Exchange 2007 or Exchange 2010, you can run a cmdlet as LMurthy mentioned to get the number of the messages. Otherwise, Message Tracking is a good tool to calculate the number of the messages. As an additional information, please refer to the link below: http://www.msexchange.org/tutorials/Exchange-2007-Message-Tracking-Part1.html Thanks.
