In Redemption, I can query the recipients collection for each appointment and fetch the MessageResponseStatus to see if the recipient has accepted or declined the meeting. I am working on changing our implementation to use the MAPITable functionality in Redemption, but I need the MAPITag for that property. However, I can't find one that looks right.
Which MAPITag property should I request to get that value?
I tagged CDO because MessageResponseStatus is a CDO property under the covers, but must map to a MAPI field down deep.
I figured it out. Looks like PR_RECIPIENT_TRACKSTATUS (0x5FFF0003) is the MAPITag I was looking for.
