Maildir Converter Tool (2026 Enterprise Edition): frequently asked questions

All 5 technical & workflow FAQs
What is the difference between Maildir and Maildir++?

Standard Maildir organizes messages into cur, new, and tmp subdirectories for a single mailbox. Maildir++ extends this by supporting nested subfolders using dot prefixes (e.g. .Sent, .Drafts). Prism Maildir Converter fully supports both structures.

Can I convert Maildir files directly to Microsoft 365?

Yes. Prism Maildir Converter includes native OAuth 2.0 Modern Authentication to upload Maildir messages directly into Microsoft 365 and Google Workspace mailboxes without intermediate PST files.

How does the tool handle large directories with hundreds of thousands of files?

Prism utilizes a bounded asynchronous producer-consumer queue with file descriptor recycling, so large directories are read in manageable batches.

Does the converter preserve email attachments and formatting?

Yes. Prism parses raw MIME streams to extract all inline and file attachments, HTML/RTF styling, headers, and flags.

What are the limitations of the free trial version?

The free evaluation trial lets you test all features and converts up to 50 items per folder. Purchasing a license removes all restrictions.
