COM

I want to get the context menu items on the mail item(outbox of outlook) programmatically from my outlook add-in. I ideally want to programmatically in C# get the context menu item on a mail item and perform invoke operation on the custom context menu item say "MyContextMenuItem". Everything getting context menu on mail item, iterating to find my item and performing the click,  should happen programmatically.  I googled around and found to add context item but not able to retrieve programmatically. Your reply would be of great help.Please Find the attachment for more details.

Thank you..
