Keeping the original folder structure is important when moving Outlook emails to an IMAP account. It helps users find messages in familiar folders after migration. Before starting, check that the destination IMAP account is configured correctly and has enough space for the mailbox data. The Aryson PST Converter Tool can import PST data into IMAP and maintain the original folder hierarchy. Users can add one or multiple PST files, preview mailbox folders, and select the data they want to transfer. When you import PST files to IMAP, the tool also provides date-range filtering and duplicate email removal. These options help users narrow the data being transferred and avoid migrating repeated messages. Review the selected folders and settings before starting the process.
If you want to import PST files into an IMAP account while preserving the original folder structure, you can try the WholeClear PST to IMAP Converter. It is designed to migrate Outlook PST emails directly to an IMAP server while maintaining the folder hierarchy, email formatting, metadata and attachments.
The software supports bulk PST file migration, selective folder import, and password-protected or archived PST files. Another benefit is that it can do the migration without needing to install Microsoft Outlook. You can process the conversion on Windows, Linux, and macOS without needing Outlook installed.
