Manually converting Olm to Pst is a free approach for your data migration between Mac and Windows Outlook. It works best when there are one or two folders and a quick internet connection.
Simply create a new dummy IMAP account (Using Gmail, for instance). Then enable the IMAP settings for your email account. Next, add that new account to your Mac Outlook and sync the data to the server. This will copy everything to your online server of the email account.
Now go to your Windows PC, open Outlook, and add that same account here. Sync the data from the server to the Outlook client, and you are done.
If it is not clear, I should inform you that this method brings with itself innumerable complications. First of all, it should only be done when the database is small. Secondly, even if the database is small, it could take a lot of time and the conversion may not even be accurate, losing information along the way and affecting data integrity.
