If you are trying to migrate IMAP emails into Zoho Mail without losing folder structure, use a professional IMAP migration solution such as MacSonik IMAP Backup Tool. Start the software and sign in with your source IMAP account credentials. The tool lets you preview mailboxes and select specific folders or entire accounts for migration. Choose Zoho Mail as the destination platform and authenticate your Zoho account. Enable folder hierarchy preservation so all inboxes, subfolders, and mailbox organization remain unchanged after transfer. You can also apply date filters, exclude attachments, remove duplicate emails, or migrate multiple mailboxes simultaneously. Once settings are configured, begin the migration process. The software securely transfers emails while maintaining data integrity, metadata, and folder structure. After completion, verify the migrated data in Zoho Mail to ensure every folder and email appears exactly as it did originally for a smooth and reliable migration experience.
