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?
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.

It is perhaps the best utility to use, particularly when you want to keep your emails with attachments intact during your migration. You can work on Mac or Windows; the tool supports both platforms.
