Unlike Aid4Mail Console, the current GUI version of Aid4Mail 4 cannot export a source MAPI profile or PST file to a target MAPI profile or PST file.
The workaround is to first export your emails to the Outlook MSG format, and then re-export those files to your target format. For more detailed instructions, please see this article: how to migrate from PST/MAPI to PST/MAPI
Please be aware that Aid4Mail version 5 can converter between PST and MAPI profiles in the GUI interface.
