I use Outlook 2010 and OWA interchangeably, with hosted Exchange.  Recently we changed company domain, so my email address from dinfo@olddomain.com to dinfo@newdomain.com and the old domain is still active for a few months transition.  It was arranged to have forwarding from old domain to new domain, so either one arrives in my new inbox

I sent out an update to my contacts but some are still using the old address.  If I can find who is still sending to my old address, I can get them to change. 

Is there a way to see either in a column my inbox what the original To: email address was in the message header? If it's not possible in the inbox listing, maybe there is a way to inspect each message, but that is sure tedious.

Hi,

How was it arranged to forwarding emails from old domain to new domain? Was it achieved via Exchange transport rule or some other methods?

Meanwhile, please try creating the following rule to check on the message header to see if it will work:

Please let me know the result.
