How to Transfer Maildir to Microsoft 365 Cloud Account?
As Maildir creates separate files for each email using RFC 822, when you are dealing with thousands of emails, Maildir becomes difficult to manage. If you have thousands of emails, then you will also have thousands of Maildir files. In this condition, Maildir is not a good choice, as managing a large number of email files is not reliable. So, to overcome these challenges, users want to import Maildir to Microsoft 365 to easily store and access emails from the cloud.
When performing migration manually, there is the possibility of data loss, incomplete data transfer, folder hierarchy will not be maintained, lack of permissions, and authentication issues. These issues not only affect the performance of the migration but also result in data loss, extended downtime, and frustrate end users who can’t access email immediately.
Since the Maildir file is not compatible with Microsoft 365 so you can’t import it directly. You need third party apps or can also use Maildir to Microsoft 365 Migration Tool to get faster and accurate results.

How to Migrate Maildir to Microsoft 365 Manually?

- Log in to Microsoft 365 Admin Center.
- Create user accounts for all Maildir files.
- Assign Exchange online licenses.
- Wait until mailboxes are fully provisioned.
- Go to the Exchange Admin Center.
- Navigate to Migration and select IMAP Migration as migration type.
- Create a CSV file that stores the IMAP Server details and user credentials to import Maildir to Microsoft 365.

When Manual Method Fails?
