Introduction to Mac-to-PC Outlook Migration
Outlook for Mac and Outlook for Windows use different data file formats. Outlook for Mac exports mailbox archives to OLM files, while Outlook for Windows mostly uses PST files. This can be a problem when users are moving from Mac to Windows and require access to previously archived emails, contacts, calendars or other mailbox information.
Outlook for Windows doesn't generally let you open an OLM file directly. Instead, the user has to convert the OLM archive to a Windows compatible file format such as PST, and then open or import the resulting PST in Outlook. In this guide, you will learn what OLM files are, why you cannot open them directly in Outlook for Windows, and how you can make Mac Outlook archives useful in a Windows computer.
What Is an OLM File and How Does It Work?
OLM (Outlook for Mac Data File) is a file format for archived Microsoft Outlook for Mac data. It supports mailbox information exported from Outlook version for Mac, including mail items, attachments, folders, contacts, calendars, and other Outlook data which Outlook supports.
The OLM files are useful for the users when they want to make a backup of their Mac Outlook mailbox or want to transfer archived information between Mac systems. However, the fact that they are platform-specific limits the compatibility when the same archive needs to be accessed using Outlook on Windows.
Why Outlook for Windows Cannot Open OLM Files Directly
The main issue is compatibility of file formats. Outlook for Windows uses PST (Personal Storage Table) for many of its local mailbox and archive operations whereas OLM is for Outlook on Mac.
Therefore, if a user copies an OLM file from Mac computer and tries to open it in Outlook for Windows, it will not be able to access the content of the OLM file directly.
To do this, one practical solution is to convert OLM file to PST. Once the conversion is done, the generated PST can be opened or imported into a compatible Outlook installation on Windows.
How to Convert OLM to PST Using Specialized Software
The most practical way to get to an OLM archive on Windows is to convert it to PST format.
Step 1: Locate the OLM Archive – Locate the OLM archive exported from Outlook for Mac. Make sure that the file is accessible and you have enough free storage space for the converted PST. Also, it is suggested that you keep the original OLM file backed up and unaltered.
Step 2: Select an OLM to PST Converter – Microsoft Outlook for Windows has no direct option to convert OLM to PST, so users have to use third-party conversion tools. A specialised application can read OLM archive and extract its mailbox folders. Then it can create a PST file, which can be used with Outlook for Windows. When users want to convert Mac Outlook archives into PST format for accessing them with Windows-based Outlook, they can use Softaken OLM to PST Converter.
Step 3: Import OLM File – Upload the OLM file to your chosen converter by using its file selection facility. You may be able to preview the mailbox structure before you start the conversion process, depending on the application. Check the available folders carefully to see if the data needed is there.
Step 4: Choose the Mailbox Data You Want – If the software has selective conversion, select the folders or mailbox items to export. This can be useful if the OLM archive contains large amount of unnecessary data. For example, users can choose Inbox, Sent Items, Projects, Clients or other custom folders.
Step 5: Select PST as Output – Select PST as the destination format and configure the available output settings. Select a location with sufficient storage space for the resulting PST.
Step 6: Begin Conversion – Start OLM to PST Conversion. The software will extract the selected OLM data and create the respective PST file. Check output after conversion and make sure critical folders, emails and attachments are there.
Step 7: Open or Import PST File in Outlook for Windows – Open Outlook for Windows and use the options to open or import Outlook data files. Choose the new PST file and allow Outlook to load the mailbox data. Then you can access the converted emails and folders from within the Windows Outlook environment.
