They had 4.2 GB of OLM archive containing more than 15,000+ emails, client contracts, and invoices. They needed a reliable, lossless migration solution for both Windows and Mac. However, the problem was that ProtonMail didn\u2019t support OLM natively, and the agency didn\u2019t have any active Outlook profile. Free converters failed to make the import, and the manual method didn\u2019t work well. So, they used the SysInfo OLM File Converter and imported all the files in a single go without hassle, data loss, or other risks. The folder structure remained preserved, time and cost were reduced, and accuracy increased.\u00a0<\/p>\n<\/div>\n\n<p><strong>Also Read: <a href=\"https:\/\/www.sysinfotools.com\/blog\/import-olm-to-godaddy\/\" target=\"_blank\" rel=\"noopener\">Import OLM to GoDaddy Email Account<\/a><\/strong><\/p>\n\n\n<h3><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Whether you plan to import OLM to ProtonMail on Windows or Mac, this guide will help you out.
