Stellar Converter for OLM – The Best Tool for Converting OLM to PST

Stellar Converter for OLM

Mac and Windows versions of Outlook save a local copy of your inbox in a data file, but the formats are different. All versions of Outlook for Mac 2011–2019 save mailbox information in an OLM file in the user profile folder.

You can also easily export your mailbox contents (emails, attachments, contacts, notes, etc.) from Outlook for Mac to an OLM file with just a few clicks. Unfortunately, you cannot import the OLM data file from Outlook for Mac into Outlook for Windows. Email contents stored in an OLM file will need to be converted to the PST format supported by Outlook for Windows before they can be backed up or accessed in Outlook.

This is where the Stellar converter for OLM comes into picture. Stellar Converter for OLM is a third-party utility that makes converting easier by hiding the technical details from the user behind an easy-to-use interface. Let us learn more about the software in the coming sections:
