That’s a useful overview. One thing I’d add is that many users underestimate the importance of previewing mailbox content before starting a large conversion. Being able to verify folders, messages, and attachments first can help avoid surprises later, especially when dealing with older archives.
I’ve also found that conversion speed becomes a major factor when working with large OLM files containing years of email data. Tools that preserve folder structure and metadata accurately tend to save a lot of time during migration.
For anyone moving from macOS to Windows permanently, it’s worth testing the converted PST file afterwards to make sure contacts, calendar entries, and attachments were transferred correctly, not just the email messages themselves.
