I have encountered a few cases where a PST contains messages with thousands of recipients. In these instances when extracting and saving the MAPI message as an MSG, just extracting the message as a MapiMessage object takes a long time, several minutes per message. Using both the PersonalStorage#extractMessage and PersonalStorage#extractMessageToFile causes this behaviour. It appears to be due to the large recipient count in the messages. I’ve included a link to a zip file in DropBox containing example Java code to reproduce the issue as well as a PST containing messages with several thousand recipients which reproduces the problem. Thank you for the help
I’m using Aspose Email For Java 20.6 and Java 8 on Linux.
