In this post, I will show how to view a delivery for a Sent Item. This report, which can be seen from Outlook and OWA, will provide information on the status of an email such as: when the message was submitted, delivered and if it was read.
I recently worked on an issue where a client noticed four Archive mailboxes in Outlook with her name. To provide some understanding about the Exchange environment, the servers were running Exchange 2010 SP3 RU5. Also, the users have Outlook 2010 SP1. Although the mailboxes showed her name in the display, they actually belong to her delegates. This was verified by viewing the Archive mailbox folders and their content.
