Yes, IMAP migration can preserve email attachments when the migration method and destination support transferring them correctly. During the process, attachments are generally transferred along with their associated email messages, keeping them accessible in the destination mailbox. However, missing attachments can occur because of file size restrictions, storage limitations, unsupported formats, connection interruptions, or incomplete migration jobs. To avoid these issues, verify the destination mailbox capacity, maintain a stable internet connection, and check a sample of migrated emails with attachments before completing the entire transfer. The Cigati IMAP Backup Tool supports migrating emails from IMAP-enabled services while retaining attachments and folder hierarchy. It also offers bulk mailbox processing and migration reports to help users monitor the transfer and identify failed items. After migration, compare the source and destination mailboxes and open important attachments to confirm their integrity. Keeping the original mailbox unchanged until verification is complete provides an additional safeguard against accidental data loss during email migration.
