Quick and Painless

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 Converter Pro 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 Converter Pro 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. Only thing missing from OLM Converter's instructions was the need to use Finder to change .VCF and .ICS files so that they open with Contacts and Calendar respectively instead of Outlook as the default. Now I just need to move my Notes out of Outlook and it's bye bye bye! Thanks!

Well worth the money

Trying to preserve data from my PC and never have to look back. This app was well worth the money. Several thousand emails preserved with hierarchies intact! I had only 2 issues, both of which I suspect have to do with the Outlook ‘exported’ .oml file. For some reason, only 1 contact was picked up. And I had multiple calendars. Only the default Outlook calendar was exported. No way to specify others. So, I had to do some work to get everything I was interested in on the ‘default’ calendar. Then, the app worked as advertised. So, GIGO. Can’t fault OLM Converter Pro for that. Shame on Microsoft for dropping export of mbox files from Office 2011, but OLM Converter Pro really ‘answered the mail’.:-)

Worked like a charm!

Had an old file that had some valuable info in it. It was gathering dust until I needed some docs I had painstakingly put together and spent the $35 to import this Outlook Mac .olm file into my Apple mail. It worked perfectly. With many gigs of data, it flawlessly imported both my calendar and my emails and attachments. Totally worth it as it’s saved me so much time already.
