MapiType AbchPerson Not Supported

Trying to get the contacts, which are identified as MapiType.AbchPerson.
Anyhow, got this error:
The IPM.AbchPerson message class is not supported by now
A first chance exception of type ‘System.NotSupportedException’ occurred in Aspose.Email.dll


Please share the sample input file and code example to reproduce this issue. We will investigate the issue and provide you information on it.

Please kindly ask the devs if AbchPerson class is supported or not and how to process it?


We already logged a ticket for this case as EMAILNET-40817.


Please find the detail about IPM.AbchPerson from here:

Unfortunately, we were unable to find more information about it. Since IPM.AbchPerson items may be located in the Contacts folder, you should explicitly check the message class to avoid converting it to a MapiContact.

So, there are two ways either save it in a MSG format or ignore it.

var msg = pst.ExtractMessage(messageInfo);

if (msg.MessageClass == "IPM.AbchPerson")
    // save or ignore
