The mailbox archive contains a copy of email messages, contacts, calendars, and other mailbox data stored locally on the device itself. As the .olm format is exclusive to Mac systems, users often face difficulty opening them on a Windows PC because there isn&rsquo;t a native way to open and view their contents. Moreover, you cannot view OLM file on a Mac without Outlook for Mac app. In this blog, we&rsquo;ll explore ways to view OLM files, both on Mac and Windows, using a specialized OLM viewer and converter tool.<\/p><h2 class=\"wp-block-heading\" id=\"how-to-view-olm-files-on-mac-and-windows?\">How to View OLM Files on Mac and Windows?<\/h2><p class=\"wp-block-paragraph\">Let&rsquo;s us explore some ways to view <a href=\"https:\/\/www.stellarinfo.com\/blog\/what-is-olm-file-extension\/\">Outlook for Mac (OLM) data file<\/a> on both Mac and Windows systems.<\/p><h3 class=\"wp-block-heading\">Part 1: View OLM file on Mac:<\/h3><p class=\"wp-block-paragraph\">You need to first <a href=\"https:\/\/www.stellarinfo.com\/blog\/find-olm-file-location-in-mac-outlook\/\">locate the OLM file stored on your Mac<\/a> before you proceed. Next, you can use either of the two ways &ndash; direct import into Outlook for Mac or a free online utility &ndash; to open and view the contents of your OLM data file on your Mac.<\/p><h4 class=\"wp-block-heading\">Method 1: Import .olm file in Outlook for Mac:<\/h4><p class=\"wp-block-paragraph\">You can open the .olm file using Outlook&rsquo;s built-in Import wizard.

Because of this reason, you are unable to open them natively on Windows or even on a Mac computer without the supporting email client app. To view OLM files on any device, you can use the <strong>Stellar Online OLM Converter<\/strong> for free to quickly view an OLM file of size <strong>&le;100 MB<\/strong> at no cost and without Outlook for Mac. If you want to open and view OLM files without any limitations, you can opt for <strong>Stellar Converter for OLM<\/strong> &ndash; a specialized desktop application that can help you preview the OLM file data using its demo version. You can get its license and use it to convert and save the Outlook for Mac mailbox file (.olm) items to file formats, such as PST, MSG, and EML.<\/p><h2 class=\"wp-block-heading\" id=\"faq\">FAQ<a
