User Query: “My name is Alex Thompson. I have been working with Outlook for the last 10 years and recently changed my company, so now all my important emails are stored in Outlook as OLM files. I just switched to Hotmail because I need cloud access on my devices, and Hotmail does not support OLM files. Can anyone help me and tell me how to transfer my OLM to Hotmail without losing my email or attachments?

Summary: When you import OLM files to Hotmail, it can be difficult since Hotmail doesn’t support the OLM format directly. All mailbox data, including emails with attachments, can be stored in OLM files when using Outlook for Mac, and Hotmail works in a cloud environment to access your email from any device. In this blog, we will learn why many users migrate like Alex and the available solutions for it. For quick and risk-free results, using the MSOutlookHelp OLM Converter Tool is the best approach for zero data loss.


What Are OLM Files?

Outlook for Mac employs OLM files as the default storage files. OLM files contain emails, contacts, tasks, notes, calendars, and attachments. OLM files can only be viewed in Outlook for Mac, and do not work with webmail services like Hotmail.

Top 5 Reasons to Import OLM Files to Hotmail?

Users open OLM Files in Hotmail for several reasons:

  1. Hotmail accounts can be opened from any browser or mobile app.
  2. Cloud storage protects emails from corruption or accidental loss.
  3. Hotmail keeps your mailbox updated across all devices.
  4. Hotmail organizes all of your folders, metadata, and attachments, making it easy to manage your emails.

Methods to Import OLM Files to Hotmail

There are two ways to move OLM data into Hotmail:

  1. Manual migration using IMAP configuration in Outlook.
  2. Automated migration with a professional OLM Converter Tool.

Method 1: Transfer OLM Files to Hotmail via IMAP

This manual method consists of connecting your Hotmail account with Outlook by using IMAP sync to transfer emails.

  2. Second, click on the settings icon on the top right, and select Options. Next, click on More mail settings to continue. 
  3. Next, select the Accounts section and then click on Import/Export. Now, choose Import from another program or file, and then select Next.
