There are many possibilities to lose your Exchange Database. It may include accidental deletion, dirty shut down, Jet errors, malicious software, synchronization issues, and corrupt header files of your database.
Among various software recovery tools, here we introduce one of the good and efficient third party tools. EdbMails EDB to PST Converter tool is one of the professional third party tools. It is trusted by millions of users around the world.
EdbMails recovers all mailbox items like Emails, Calendars, Contacts, Drafts, Notes, etc. including attachments. It supports Exchange Server 2003, 2007, 2010, 2013, 2016, 2019 and outlook versions 2000, 2002, 2003, 2007,2010,2013,2016 and 2019. EdbMails supports both 32-bit and 64-bit Windows operating system.
The tool is built on the most advanced algorithms that can recover every last bit of information from your exchange database with ease. It also supports granular exchange recovery allowing you to export exactly what you need.
EdbMails does not require any key to use the application. You can test all the features using ‘Free trial’ version. No need to be a technical expert to use the application with its ease use of GUI. Within a few clicks you can perform safe and secure EDB to PST conversion.

I would suggest instead of converting you can just migrate. It'll save you a lot of trouble.
Follow these steps to migrate:
1. Create Office 365 users.
2. Create migration endpoints on Exchange to connect to Office 365.
3. Create a migration batch.
4. Import the migration batch to Office 365.
5. Point the MX records to office 365.
6. Delete the migration batch.

I found a blog that explains this process step by step. Here it is Exchange migration to Office 365.


I hope this helps!

That's really helpful. Thanks. After migration to Office 365 I started thinking about changing some other stuff I use and I decided to migrate to magento. I used to be admin of the site and office 365 was necessary for my job but I also would like to make my own one so I've checked https://magecloud.agency/migration-to-magento-2 to find more info about this movement.
