Did you know that if you use Microsoft Exchange 2010 you can check their own email delivery reports directly from Outlook Web Access. Just log into your outlook web access interface, go to Sent Items, r-click the email and choose “Open Delivery Report”. You might see a prompt asking you to allow pop-ups to see this window.
The server logs only go back a few days depending on email volume so all emails will not be listed but if you are looking for a recent messages delivery history then this is a great place to start looking.
Please give us a call at 512-832-6209 if you have any questions.
