User Query:
“So I use Microsoft 365 for all my work emails, but now I’ve got to open some of them in another app that only works with EML files. I tried looking around but couldn’t figure out a proper way to do it without messing up the formatting or attachments. Is there any simple and reliable way to get this done?”
Honestly, this issue pops up more frequently than you think. You go searching online, and suddenly you’re going through long tutorials and messy workarounds. I’ve been there. Most of the steps are either too technical or just don’t work the way you expect. Now, while trying different options, I came across this utility called the SysInfo Office 365 Backup Tool. It’s just a pretty straightforward way to export Office 365 emails to EML and other formats.
If you’re planning to transfer Office 365 emails to EML, there are multiple ways to achieve this. In this post, I’ll break down both the manual trick and the easier route using a tool, so you can choose the method that works best for you.
There are various advantages of exporting Microsoft 365 emails to EML. Here are various reasons why users need to transfer:
You can take your emails with you
Unlike some bulky formats, EML files are light. You can move them around pretty easily, copy them to a flash drive, or drop them in a folder.
They open in almost anything
Whether you’re using Thunderbird, Apple Mail, or some basic built-in email app, there’s a good chance it supports EML.
You get your backup
Look, cloud platforms are great, but it’s always smart to have a personal backup. Saving your emails as EML gives you that extra layer of security if something ever goes wrong with your Office 365 account.
You don’t even need an email app to read them
One of the coolest things? If you’re just trying to check the contents of an email real quick, you can open an EML file in Notepad. No fancy tools required.
Long-term storage without the hassle
For businesses or users who need to hold onto emails for legal or record-keeping reasons, EML makes it easy. You can store them for years and still access them whenever you want, without needing to stick with the same email service.
If you’re using Microsoft 365, there are a couple of ways you can save your emails in the EML format, depending on what works best for your situation. Some methods are good for a single file, while others are better when you’ve got a lot to export.
Manual techniques are useful when you only need to save a few emails and don’t want to depend on third-party tools. These methods are simple but best suited for smaller tasks.
If you’re accessing your Microsoft 365 mailbox through a browser (like Chrome or Edge), here’s a simple way to save emails. Steps can be followed as:
Note: Some browsers may try to save it as an HTML file. Just change the extension to .eml after saving, and it will still work in most email apps.
If you’re using the desktop version of Outlook, especially an older one, you won’t find a direct option to save emails as EML. But there’s a simple workaround. You can first save the email as a .txt file, then rename or convert it to .eml. Now, let’s see that:
Note: This method works best if you’re okay with a bit of manual handling. Just remember, formatting may not be perfectly maintained compared to a true EML export.
