Not that I am aware of. Considering it would take several hours to do this, (narrow down the *.dll associated with ActiveSync/Exchange), edit it, save it, and edit the poutlook.exe to have the application image you want, it is rather time consuming to do so. After editing the necessary files, you would need to halt poutlook.exe, and import your edited files. After that, you will need to reset your TP.
