You run the Export-ActiveSyncLog cmdlet in Exchange Management Shell on a Microsoft Exchange Server 2007 server. This cmdlet parses the Internet Information Services (IIS) logs and then returns information about Microsoft Exchange ActiveSync usage. The return information includes "Items Sent" and "Items Received" for users. The values of "Items Sent" and "Items Received" should include emails, calendar, contacts and tasks. However, you find the following two issues:
"Items Sent" does not equal to "Total Emails Sent" + "Total Calendar Sent" + "Total Contacts Sent" + "Total Tasks Sent"
"Items Received" does not equal to "Total Emails Received" + "Total Calendar Received" + "Total Contacts Received" + "Total Tasks Received"
This issue occurs because the calculation method of Exchange Server 2007 is incorrect.
To resolve this issue, install the following update rollup:
2530488 Description of Update Rollup 3 for Exchange Server 2007 Service Pack 3
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
