Thank you for your question regarding Outlook Web Access.
As I mentioned above, this is not a simple thing to 'fix'. In a
nutshell, the problem is that OWA uses the same template for all of
its default mail folder views, including the Sent Items.
To change this requires that your Exchange administrator(s) become
familiar with the Exchange data schema used by OWA, so that they can
configure the Sent Items folder to use a different template than the
rest of the mail folders.
One complication is that Microsoft, for reasons known only unto them,
have 'broken' the link to get to the documentation through MS TechNet,
the online library of technical information that all MS-trained folks
I was able to find a copy of the necessary document on another site;
please download this document and store it locally, as there is no
guarantee that it will remain available:
Customizing Microsoft® Outlook® Web Access - White Paper
While it is important to read the whole document in order to
understand how OWA works, I would draw particular attention to pages
64 and onwards. This is where custom views are discussed. This is also
where the problem becomes most acute. The two methods available for
customizing the view for a folder are both folder-centric, meaning
that each folder has its own view setting. For a Public Folder, the
Exchange administrator would only have to set the view once. However,
Sent Items folders exist in every mail account. So, even if the
Exchange administrators are successful in getting the Sent Items view
changed for one user, they would most likely have to do this for each
user individually. I have not worked on this myself, so I cannot say
how much effort is involved. I suppose it is up to your Exchange
administrator team to determine if it is worth it!
An alternate solution, albeit less desirable, is to add the To: field
to the standard view; however, this would waste an entire column's
worth of space to list your own address over and over again, in every
folder other than Sent Items.
I hope this information is useful to you.
