User Query:
BizAdmin_Neel on Spiceworks Enquired: I tried to export contacts from OLM file after migrating 30 employee accounts from Mac Outlook to a new CRM platform. Each OLM file contains contacts that need to be exported individually in CSV format, but the manual drag and drop method inside Outlook for Mac is taking long hours & is not exporting all contact fields correctly. Some phone numbers and address fields are just disappearing after export.
Is there a quick & more reliable method to bulk extract contacts from multiple OLM files at once while keeping all contact fields completely intact?
Users often find themselves in situations where they need to extract only contacts from an OLM file or directly from Mac Outlook. These scenarios, which are common among both personal and business users, include migrating from Mac to Windows, creating a backup, transferring to other platforms, optimizing storage and migration, and better organization and management. Here are some common scenarios:
These scenarios highlight the critical importance of contact details, prompting users to seek reliable methods for extracting only contacts from their OLM files.
While multiple ways exist to extract contacts, the efficiency of the process is key. Review each procedure below and select the one that best suits your specific requirements.
If you still have access to your Mac Outlook account, this method allows you to save contacts in CSV format. Follow these steps:

Limitations: This method is only available to users with active Mac Outlook access. Additionally, it may not ideally export all contact fields into the text file.
Directly exporting data to .vcf from Outlook for Mac is not supported. However, you can use the following workarounds:
Limitations: The drag-and-drop method does not support batch export of contacts to VCF, making it very time-consuming if you have a large number of contacts.
This process is applicable only if your Outlook contacts are synced to your Mac’s Contacts app via iCloud. Follow these instructions:
Limitations: This method requires contacts to be synced to Apple Mail via iCloud first, as it doesn’t work directly with OLM files. It can make the process more complex to perform.
If you only have orphaned OLM files (not connected to an active Mac Outlook account), using professional software is the most reliable and convenient solution. Aryson OLM Converter is a highly recommended tool for exporting contacts from Outlook Mac OLM files. This utility supports extraction from multiple OLM files simultaneously, regardless of their size. Furthermore, it ensures that contact fields and the overall structure remain intact after conversion, providing you with peace of mind.
This process is reliable, secure, and user-friendly. You can download and run the free trial version of Aryson OLM Converter to test its authenticity and reliability before purchasing, ensuring that your data is in safe hands.
Exporting contacts from Outlook for Mac should not be a difficult task. This guide has covered various approaches, from manual methods to quicker, professional solutions.

Ans– To extract contacts from an OLM file on Windows, you will need to use a professional OLM Converter Tool. This type of software allows you to specifically select the contacts section within the OLM file and export them into formats like CSV, vCard, or Excel without requiring Mac Outlook to be installed.
Ans- Yes, you can extract contacts from an OLM file for free by importing the OLM file into Outlook for Mac and then manually exporting the contacts. However, this method strictly requires access to a Mac system with Outlook installed. On Windows, while some free OLM viewers might display contacts, they typically do not support exporting data without a paid upgrade.
