Microsoft 365 users may need to save emails as EML file for backup, migration, archiving, legal review or use with another email application. Outlook on the web and New Outlook offer built-in options to download an email as an EML file for one message. For bigger mailboxes, folders or bulk exports, a dedicated Office 365 to EML converter can make the process easier.<\/p>\n

This tutorial will walk you through the process of exporting Office 365 emails to EML files by means of native Outlook options, Thunderbird and an automated conversion tool.<\/p>\n

Quick Answer:<\/strong> If you want to save one Office 365 email as an EML file, open it in Outlook on the web or New Outlook, select More actions > Download or More actions > Save as, and save the message. For bulk Office 365 to EML export, go for a dedicated converter like Advik Office 365 to EML Converter to export multiple folders and emails in one go.<\/p>\n

What is an EML File?<\/h2>\n

An EML file is a typical email message file, containing one email, with the message content, sender, recipient, subject, date, and other message information. Attachments and formatting can also be maintained, depending on the email and the export method you select.<\/p>\n

EML files are supported by most email apps and can be useful for transferring individual messages between compatible mail clients, keeping offline copies, or saving emails outside a Microsoft 365 mailbox.<\/p>\n

EML is different from PST which is used mostly to store Outlook data. It is used to store individual email messages mostly.<\/p>\n

Can Office 365 Emails Be Saved as EML?<\/h2>\n

Yes. EML files can be saved on Office 365 emails using supported Outlook interfaces .<\/p>\n

Outlook on the web can download a message as an EML or MSG file, according to the current Outlook documentation from Microsoft. New Outlook also includes a Save as option, which allows you to save messages to a computer or cloud location.<\/p>\n

But saving individual messages isn\u2019t the same as bulk exporting an entire Office 365 mailbox. If you have hundreds or thousands of emails in multiple folders, saving each message manually can be impractical.<\/p>\n

That is when an automated Office 365 to EML converter will come in handy.<\/p>\n
