Created attachment 37462 [details] 2 files - a msgfile and a dumpfile I wish it would be possible to read an UserProperties which is added to an Outlook-message (.msg) using VBA. I know it can be found by using VBA (eg msg.Userproperties("outlookid")), but I want to use Apache POI instead if it´s possible. I will attach both the msg-file and the dumpfile which I got from using HSMFDump. The data I am looking for is "outlookid" and "Projektnr"
