A reliable way to import IMAP emails to Office 365 is by using a professional migration tool. Manual methods are slow, require complex configurations, and often fail with large or multiple accounts. Tools like SysInfo IMAP Backup Tool make the process simple by directly migrating IMAP emails to Office 365 while keeping attachments, folder hierarchy, and metadata intact. It also offers batch migration, filters, and duplicate removal, ensuring a secure and accurate transfer.
