Yes, you can migrate multiple MBOX archives to Microsoft 365, but the process depends on the method you choose. Since Microsoft 365 does not directly import MBOX files through its standard mailbox interface, you may need to use an intermediate email client or convert the archives into a supported format.
For a small collection, you can import MBOX files into a compatible email client and transfer the messages through an IMAP connection. If you have many large archives, converting them to PST and using Microsoft's supported PST import service may be a more suitable approach.
Before you import MacSonik MBOX to Office 365, check the size of each file, organize the archives, and ensure that your destination mailbox has sufficient storage. Keep backup copies of the original files throughout the process.
After migration, review the transferred emails, attachments, and folders to confirm that everything is accessible. Testing a small batch first can help you identify potential issues before processing the complete archive.
