Exchange 2010 provides an easy way to verify whether that very important message was delivered to every recipient with a new feature we call delivery reports.

Delivery Reports contains delivery information about messages you sent, such as:

  • Why didn't my message go through?
  • Where is my message now?
  • Who received my message?

And about messages you received:

  • Am I a member of any of the groups addressed in this message?
  • Why is this message in a folder and not in my inbox?

Delivery Reports can be accessed by users from Outlook Web Access or by clicking on the "Options" button and then going to "Organize E-mail".

Administrators can access Delivery Reports from the Exchange Control Panel on the "Reporting" tab, and if the Administrator has access to the Exchange Management Console, the "Toolbox" section contains a link to "Message Tracking" where they can search for Delivery Reports. The Message Tracking tool included in previous versions of Exchange has been renamed "Tracking Log Explorer".
