An issue with ID EMAILJAVA-34540 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

Its showing that EMAILJAVA-34540 is in a closed state, but I never received a release update. Can you please let me know which version it was included in?


We have investigated this on our end and In this case, the you just needs to handle the exception. If you further saves the message, it will be saved with MapiMessage without loss the properties.

If you want to read some properties, it can be read with MapiMessage. The MapiMessageItem class is just a wrapper created for the convenience of reading the properties of a contact, calendar, task, etc., since most of properties are stored as Named Properties and access to them using MapiMessage via id is not convenient.
