There are various ways to transfer OLM files in Gmail. This guide explains all the methods with step-by-step instructions.


Gmail and Outlook are two widely used email clients. Gmail is developed by Google, and Outlook is developed by Microsoft. MS Outlook has two different programs: Outlook for Mac and Outlook for Windows. Gmail, on the other hand, is available on both Mac and Windows. If we talk about file formats, Mac Outlook uses two file formats: OLK and OLM files. Both are used only on Mac systems.


OLK files are used to store Mac Outlook data, and whenever a user wants to transfer its Mac Outlook data to another place, it uses OLM files. The Gmail program uses the VCF file format to import and export the data. Moreover, users can connect their Gmail account with other email programs via the IMAP server. There are many users who migrate their OLM files into Gmail for backup. Therefore, we share multiple methods to convert OLM files to Gmail.


Ways to Transfer OLM Files in Gmail


Anyone can migrate Mac Outlook files into Gmail using IMAP. Users enable an IMAP account with their Gmail account and configure it in Mac Outlook. After that, move Mac Outlook data to the configured Gmail account. This method is lengthy and requires more attention. So, for an easy process, use a software method that converts OLM files into VCF format. Thus, there are two methods to open OLM files in Gmail.

  • Manual method: use the IMAP server to configure the Gmail account with Mac Outlook.
  • Professional method: convert OLM files into VCF format using the software.


Manual Method to Export OLM Data into Gmail Account


In this method, you can use your existing Gmail account. Users complete this method in three steps.


  1. Enable IMAP in your Gmail account.
  2. Configure the enabled Gmail account in your Mac Outlook.
  3. Move the files from Mac Outlook to the connected Gmail account.


After this, you are able to open the OLM files. We elaborate these steps in detail, so follow them carefully.
