I know how to get the Internet message header in Outlook, but is there also a way to see them when using Outlook Web Access (OWA)?
There is indeed a way to do this in Outlook Web Access/App (OWA) as long as you are connecting against an Exchange 2007 or Exchange 2010 server.
- Double click on the message to open it in its own window.
- Click on the Message Details icon at the top of your message.
- A new dialog window will open on the page containing the Internet Mail Header details.
Note: There is no way to access the Message Details dialog without first opening the message itself. However, this is not a security concern as attachments cannot be opened automatically, scripts are not allowed in messages and web beacons (images used for tracing you) do not automatically download.
