    Repeated errors while attempting to import MBOX to Office 365 are often caused by unsupported manual methods, authentication issues, or large mailbox files. Choosing a solution that supports direct migration can help avoid incomplete transfers and preserve mailbox integrity. The Aryson MBOX Migrator Tool enables secure migration of MBOX files to Microsoft 365 with support for bulk imports, folder mapping, email filters, duplicate removal, and complete preservation of attachments, metadata, and folder hierarchy. It works with MBOX files created by multiple email clients, helping users complete migrations accurately while reducing downtime and manual effort.
