So I just purchased this app because I was looking for a simple way to migrate away from Outlook 2011 on Mac. I've want to move out of Outlook for awhile (too many reasons to list) but have been stuck in it because I couldn't find a simply way to get out. Well, OLM to MBOX Converter was the ticket to escape. There were no reviews on this app posted yet so I was a little worried as I do rely on customer feedback when deciding to purchase software but I figured I'd take a chance. I'm happy to say that OLM to MBOX works exactly as advertised. It took my 20k+ emails in Outlook, thousands of contacts and calendar items and moved them into formats that I could import into Apple's Mail, Contact and Calendar programs. We're talking all in about 30 minutes, no errors, no hiccups and no problems of any kind. My Outlook folders are all there, the attachments, the original sent/received times, everything. Out of Outlook and it's bye bye bye! Thanks!
