Switching from Mac OS to Windows! How to move your Outlook database (convert OLM to PST)?

Written by admin

Summary: Microsoft Outlook is one of the most used email clients by many organizations and it is available for both most famous OS in the world Mac & Windows. But Outlook uses two different types of data files to store data on both platforms. OLM is Outlook data file in Mac OS, while in Windows PST file is Outlook data file. As we can’t open .olm file in Outlook for Windows. So here, we describe how to move Outlook mailboxes data from Mac to Windows PC.

Microsoft Office introduces a Mac-specific Outlook data file called OLM with Office 2011. OLM file works same for Outlook in Mac as PST file works in Windows Outlook to store all mailboxes items including Inbox, Outbox, Sent Items, Contacts, Calendar, Notes, etc. Since the OLM file only works with Outlook for Mac computers and in Windows you can’t access data in Outlook directly from OLM file. Thus, if any user switching from Mac to PC and wants to migrate all of his Outlook databases to Windows OS, then you have to export all data from OLM file to a PST file and then import the resultant PST file in Outlook for Windows.

How to Convert OLM to PST?

Manual Method:

To convert OLM file into PST format manually, you have to locate the OLM file in your Mac Computer. You can find the OLM file in either of these two default locations:

Documents\Microsoft User Data\Office 2011 Identities\Main Identity\Databases

Or

Documents\Microsoft User Data\ MS Office 2011 Identities\Main Identity\Data-Records\Message

But before directly navigating to one of these folders to find the OLM file, first, you will have to create it by exporting all mailboxes data in an OLM format file.

STEPS:

  1. In any of the folder location mentioned above, click on File > Export to open a new Export Window.
  2. Select all items available in this folder.
  3. Here a new option appears “Delete items after exporting”. Check “Do not want to delete item” option.
  4. Next “Save As” option will appear. Here chooses a destination folder to save the OLM file.
  5. Click on Save to save the OLM file.

Once you created the .olm file, then you need to convert it into PST format using methods mentioned down below-

Note: In this method, you have to use the IMAP server as an intermediate device between different Outlooks for Mac OS and Windows to receive remote files.
