I just bought this application because I wanted a quick solution for switching from Outlook 2011 to Mac. For a number of reasons to name, I've wanted to quit Outlook for a long time, but I haven't been able to because I can't figure out how. However, the OLM Converter software was the key to freedom. I was a bit concerned as there were no reviews for this software, yet I usually rely on user reviews to decide whether or not to buy software, but I decided to take the risk. I am happy to tell you, everyone, that SysTools OLM Converter software performs well. It converted my 20k+ Outlook emails, 10,000 contacts, and countless calendar entries into formats I could import into Apple's Mail, Contacts, and Calendar apps. All this can be completed in about 30 minutes without any glitches, mistakes, or other issues. All attachments, original send/receive times, and all my Outlook folders are present. All I have to do is delete my notes from Outlook and I can say goodbye! Thank you!
