Hi there,

I try to execute a token ItemAddMimeXField() on an existing message (mail) item to store some application data to the mail. I can iterate through the existing XFields (using ItemGetMimeXFieldCount() and ItemGetMimeXField()) but I am unable to add a name value pair to this collection. The result of the DDE command is "Token failed execution!". It doesn't matter if I try to execute this method on a send or a received message.

I use .net c# for a C3PO add in and the COM objects of GroupWiseCommander.
