Hi,

I was wondering if you can help me with something. I have been trying to find a way to differentiate opening a mail item from a file (like an eml file) from opening a mail item from a mailbox.

Are you aware of how can I recognize if a mail item is opened from a file in a definitive way?

Thank you very much for helping out,

Kind regards,
Frank

Hello Frank,

Add a test button to your add-in. In the Click event of the button get the MailItem objects you want to compare and let the code stop on a break point. Now use QuickWatch to view each of the objects, expand their properties and capture screenshots of the QuickWatch window. Finally, compare screenshots to find differences between the properties of the two MailItem objects.
