Ok,

The security guard pops up when you try to access certain properties of the mail mainly around the email addresses. You can use mapilib to stop it or use redemption‘s safe mail item. or

You can use the mail items PropertyAccessor to gain access to the underlying Mapi properties

For the “TO” you need PR_EMAIL_ADDRESS (or PR_SMTP_ADDRESS)

mailItem.PropertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x3003001F"); 

I would suggest that you download Dimitry’s Outlook spy its “the” tool if you are developing Mapi/outlook etc.

You can then look up the Mapi properties and their ids to get the others
