Since Tutanota does not support IMAP, the IT team tried manually exporting EML files for 150 users.

Can I migrate emails from Tutanota to Microsoft 365 with attachments?<\/strong> <p class=\"schema-faq-answer\">Ans. Yes, you can transfer emails from Tutanota to Microsoft 365 with or without attachments using the SysInfo EML to M365 Migrator.
