Invalid Binary MIME Data Detected Error

Invalid binary MIME data detected​: This item we attempted to migrate is corrupt and cannot be migrated to an IMAP server because it has invalid MIME content.


This error message indicates the item was skipped and not migrated. In most cases, you will find that the item is non-readable from the Source mailbox (i.e., the message cannot be rendered in your email client). If necessary, consider manually forwarding affected items to the Destination. Alternatively, consider exporting and importing affected items using Outlook as it may be able to correct invalid MIME content. Please note that MigrationWiz tries to repair and normalize invalid MIME content, but this cannot always succeed.
