Aspose.Email.Outlook.Pst.MessageInfo.MessageClass is now empty!

I excitedly upgraded to Aspose.Email 1.1, but found a problem.

Aspose.Email.Outlook.Pst.MessageInfo.MessageClass is now empty, and this is critical for me. I will have to roll back to 1.0 until this is addressed. Thank you!

Best regards,


Hi Rob,

I have reproduced this issue at my end as well.

Could you please try the following workaround with v1.1?

MapiProperty messageClass = messageInfo.Properties[MapiPropertyTag.PR_MESSAGE_CLASS];
if (messageClass == null)
messageClass = messageInfo.Properties[MapiPropertyTag.PR_MESSAGE_CLASS_A];
if (messageClass == null)
messageClass = messageInfo.Properties[MapiPropertyTag.PR_MESSAGE_CLASS_W];

// Get the message class
if (messageClass != null)

Hi Saqib Razzaq,

This workaround does yield a valid MessageClass value. Thanks!

Will the next release of Aspose.Email require the workaround, or will it fix MessageInfo.MessageClass?

Best reards,
