If you are an Outlook user on Mac OS, you may be familiar with the OLM file. But if you prefer to switch to Outlook for Windows, you need to convert your OLM files into PST files in order to migrate all your existing email, attachment, etc. data to the Outlook for Windows client.

In this post, we will go through several manual approaches to convert OLM to PST files. Therefore, if you are seeking the process, then stay with this post and keep reading.

Before starting, let us know a little bit about Outlook for Windows and Mac

MS provides email platforms for both Windows-based and Mac operating systems: MS Outlook and Outlook for Mac, to accommodate Exchange integration. Outlook for Windows and Mac has a roughly comparable UI and functionality.

Actually, the distinction is that Outlook for Windows stores user mailbox records in PST format, whereas Outlook for Mac stores them in OLM file types. Furthermore, Outlook for Mac does not have the same functionality set as MS Outlook.

Generally, PST and OST are the two file types supported by Microsoft Outlook for the Windows OS. While Outlook is set up with the POP3 protocol, PST files are used to save data. But Outlook preserves its mailbox data in OST files whenever users work in offline mode with an Exchange account.

Reasons why users prefer to convert OLM to PST files

As we all know, Outlook for Windows doesn’t support the OLM format, so it is a necessary requirement to convert OLM into PST for users who want to switch to Windows Outlook from Mac. Besides, few more probable reasons are as follows:

  • The individual who is thinking of switching from a Mac to a Windows operating system, OLM to PST conversion is required if he or she wants to preserve the existing email client’s data.
  • One is partially utilizing a Windows computer at work or at an apartment. To connect his Outlook for Mac email messages, he must convert OLM to PST.
  • When it is necessary for a user to retrieve data documents from orphaned OLM files,
  • Whenever a company makes the decision to completely migrate to a Windows operating system,
  • Furthermore, the lack of a Mac setting or short-term collaboration on a Windows OS is a significant reason.

What are the easiest techniques to convert OLM to PST files manually?

We are going to describe two manual techniques. The first technique is to use the Exchange account, and the second is to use the IMAP account. Let’s start that.

Use the “Export” option in Outlook for Mac

Before starting this process, let me inform you that you must somehow manage both Outlook for Windows and Mac user accounts and need to start both at the same time.

Using the IMAP account

To migrate data from Outlook for Mac OS to MS Outlook (Windows OS), we use an IMAP account as an intermediary. As such, initially, we must set up the IMAP account in Outlook for Mac, followed by Outlook for Windows. To understand the steps clearly, we have separated them into four easy parts. Let’s see the steps.
