Free Ways to Convert OLM to PST File – 2024 Guide

Mac Outlook and Windows Outlook offer a similar UX and UI. However, there is one major difference between the two- in Mac Outlook, the mailbox data is exported/imported in OLM format. While in Mac Outlook, the mailbox data is exported/imported in PST format.  So, if you are migrating from Mac to Windows, you need to convert OLM to PST.

You can convert OLM files to PST two ways. One is to convert OLM to PST manually, which is how you can convert for free. The other way is to use a third-party tool to convert the data directly.

If you want to learn how to convert OLM to PST for free, you can apply the IMAP mailbox method we discussed in this post. However, for many users, this method is unsuitable. This is because there’s a risk of data loss and human error in this method. Additionally, you would need a fast network connection to finish the migration in a short period.
