Hi experts,

I want to write an Exchange Event Sink to add a user defined column
which should be displayed in Outlook.

I want to know -
How to define a user defined column in the Event ( I believe we add a
custom property to the email message and it appears as a user defined
column in Outlook).

I have managed to write a sample Event sync which modifies the subject
of the email as it arrives. But I also want to add a custom property/
USer defined field which can be displayed in a column in Outlook.

My code -
public void OnSyncSave(IExStoreEventInfo pEventInfo, string
bstrURLItem, int lFlags)
{
    WriteMessage("Event fired with lFlags = " + lFlags );

    try
    {
        IExStoreDispEventInfo DispInfo ;
        DispInfo = (IExStoreDispEventInfo)pEventInfo;

        ADODB.Record ado_rec;
        ado_rec = (ADODB.Record)DispInfo.EventRecord;
        //String Subject;

        ado_rec.Fields["urn:schemas:mailheader:subject"].Value = "D - This
is a demo" + ado_rec.Fields["urn:schemas:mailheader:subject"].Value +
")";

        ado_rec.Fields["urn:schemas:AAAA"].Value = "CUSTM VALUE";
//Try to add a custom property AAAA . But I think I am wrong in
specifying the URN Schema.

        ado_rec.Fields["urn:schemas:mailheader:CC"].Value = "22***@123.com";
        ado_rec.Fields["urn:schemas:mailheader:Categories"].Value =
"ABCDEDF";
        ado_rec.Fields["urn:schemas:httpmail:messageflag"].Value = true;
        ado_rec.Fields["urn:schemas:mailheader:x-message-flag"].Value =
true;

        ado_rec.Fields.Update();

        ado_rec.Close();

    }
    catch (Exception ex)
    {
        WriteMessage("ERROR MESSAGE..." + ex.Message + "   " +
ex.ToString());
    }
}

You need to look at using a Mapi editor like Outlook Spy or Mfcmapi to work
out what the propname is for the custom attribute you want to set. Eg your
custom prop should be in (PS_PUBLIC_STRINGS)
http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/
see http://msdn2.microsoft.com/en-us/library/ms526761.aspx

then just use this eg

ado_rec.Fields["http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/0x8...."].Value

Cheers
Glen
