VSTO has nothing to do with it. Outlook 2003 doesn't have a
PropertyAccessor() object and provides no access to the PR_ICON_INDEX in the
Outlook object model. Therefore you'd have to access that property using an
alternate API. Since Extended MAPI (C++ and Delphi only) and CDO 1.21 are
both not supported for use with managed code your alternatives are MAPI
wrappers such as Redemption (www.dimastr.com/redemption) or MAPI33 or such.

Hi,

So seems like it's possible to set any icon to MailItem.

Is it possible in VSTO 2005?? For Outlook 2003???



Thanks.
