I need to know the purpose of this tag. Can I use this property to extract the entryid of message file within pst, if message’s PR_ORIGINAL_ENTRYID is null ? Or Should i go with PR_LAST_MODIFIER_ENTRYID or leave entryid empty ?
We have investigated the requirements on our end. Actually, PR_OFFLINE_MESSAGE_ENTRYID has to be addressed to Microsoft support as it is not covered in Aspose.Email support coverage. Microsoft can provide must exact answer. We haven’t used this MAPI property till now in API as well.
