MFCMAPI Public Folders Contacts

Hi,

Have run into this issue where you can't edit the notes field of a contact.  In this case the contacts are in a public folder in Exchange 2007.

I am running MFCMAPI and deleting the PR_TRANSPORT_MESSAGE_HEADERS_W property, which is working.  However, not all of the contacts are visible in MFCMAPI and I don't know why that would be.

Any thoughts on this or is there a PowerShell technique for reading and deleting this property from a contact if it exists?

Thanks!
