If you’re an Outlook user on macOS, you’re probably familiar with OLM files, these are the files used by Microsoft Outlook for Mac to store your emails, contacts, calendar entries, and other data. Unlike the PST files used by Outlook on Windows, OLM files are specific to the Mac version of Outlook.

But what if you’re looking to back up, transfer, or manage your OLM files, and you’re not sure where they are stored? You’re not alone! Many users often struggle to locate their OLM files on their Mac. But don’t worry, this guide will help you understand how to find OLM file location in Mac Outlook and provide you with easy steps to find them.

Where Are OLM Files Stored on Mac?

The OLM file is created and used by Outlook for Mac to store emails, contacts, calendar entries, and other data. However, the location of OLM files differs based on the version of Outlook for Mac you’re using. Here’s a breakdown of where you’ll typically find your OLM file based on the version of macOS and Outlook you’re running.

Location of OLM Files in Different Versions of Outlook for Mac:

1. Outlook 2011 for Mac (Mac OS X 10.5 or Later)

For users running Outlook 2011 for Mac on macOS 10.5 (Leopard) or later, the OLM files are typically stored in the following location:

/Users/<username>/Documents/Microsoft User Data/Office 2011 Identities/Main Identity

  • Replace <username> with your Mac’s actual username.
  • In this folder, you will find the Main Identity folder containing the Outlook data, including OLM files.

2. Outlook 2016 for Mac (Mac OS X 10.5 or Later)

If you are using Outlook 2016 for Mac on macOS 10.5 or later, your OLM files are stored in the Group Containers folder. The location is:

/Users/<username>/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile

  • Replace <username> with your actual username.
  • The Outlook 15 Profiles folder contains your OLM files, along with other Outlook profile data such as emails, contacts, and calendars.

3. Outlook 2019 for Mac (Mac OS X 10.5 or Later)

For users with Outlook 2019 for Mac, the OLM files are stored in the same location as Outlook 2016 for Mac:

/Users/<username>/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile

  • Replace <username> with your specific username.
  • You will find the Main Profile folder here, which contains all the OLM file data for Outlook 2019.

How to Export OLM Items from Outlook for Mac?
