How to Import OLM to ProtonMail on Mac & Windows Easily

Note that Proton AG ProtonMail doesn’t support OLM format directly. Instead, it allows emails and files in EML or MBOX format. So, this file format incompatibility is the biggest challenge for the data transfer. You need to find reliable solutions to ensure your data never goes out on the verge of loss. 

How to Import OLM File to ProtonMail?

A quick answer to this question is to use the manual ProtonMail Bridge for free or with the SysInfo OLM Exporter for greater accuracy. The methods are explained below with complete solutions and their pros and cons. 

Manually Transfer OLM File to ProtonMail 

On your Mac or Windows OS, you may follow the given steps to make the transfer:

2. Choose Outlook for Mac Archive OLM File, and import it (optional).
