  • Hi,

    I would like to know which message property tag I should check to determine the message is conversation history message except message class property. Thanks.

    See the Tracking conversations section in MSDN for more information.

  • The message has IPM.Note.Microsoft.Conversation message class. The conversation is from MS Lync not tracking conversation. The message is in Conversation History folder.

  • Try using any Extended MAPI viewer such as MFCMAPI or OutlookSpy to find any other difference. I will take a look at them in the office tomorrow.

  • I found a few but not sure which one is the correct one to use.

  • What property tags are you talking about?

  • It seems you changed the message and added a screenshot.

    I see the same set of named properties in Outlook. You can use GetProperty method of the PropertyAccessor class (see the corresponding property of the MailItem class) and pass the DASL property name.

  • If I retrieve ConversationXml property and it exists, can I determine this message is conversation history message?

  • The best indicator is message class (see the corresponding property of the Outlook items). That's how Outlook recognizes what a particular message is. If you feel uncomfortable only with the message class value, you can use any additional properties like shown on the screenshot. But nobody can guarantee that they will be set up for conversation history items only.

  • In my case, I could not use the message class since it has been changed.

  • Try to check the MessageClass property value in theNewMailEx event handler. Does it return a unique value, not changed?
