Just got a kind note from Mike, a Mac user, saying that Emailchemy was the only Mac-based method he could find to convert his Windows Outlook PST file to Mac OS X Mail. 1GB in 20 minutes, not bad at all.
Anyway, he wrote to also report another quirk in Mac OS X Mail’s import feature. I say “another” because I’ve already noted (and reported to Apple) a few others. The issue he reported was that when importing mbox folders in Mail 2.0 format (Mac Mail .mbox folders are not the same as standard mbox files), Mail will import all the folders but some folders that are deeper in the hierarchy have all their messages show up blank. Mike reported that importing mbox folders in the Mail 1.0 format worked fine, however.
The problem with the Mail import bugs (I’m not calling them quirks anymore) is that they are often hard to reproduce and there may only be a few other users who ever see this issue.
This is why I recommend using Emailchemy’s embedded IMAP server (the IMAP ImportServer tool) if you can. It bypasses the import wizard by providing you a desktop mail server that you download your converted mail from. It’s as simple as creating a new email account and downloading the mail.
Aside from the bugs in the import wizard, I like using Mac OS X Mail. It’s what I’ve been using for the past several years and I haven’t seen anything else I like on the Mac yet.
