Not working with .OLM files created with OUTLOOK 2016 (OUTLOOK 365).

I tried deleting the app and reinstalling but did not work.
I tried converting the entire .OLM file that only had contacts (7,000 contacts)
I tried converting a partial version of the file (1,000 contacts)
I tried converting only 80 contacts

At the end the same result… the app was able to read the .OLM file but it crashed when it tried to convert.

When I say “crash” I mean it froze.

I waited first 5 minutes and forcequit. Then waited 15 minutes and the same. Then waited 30 minutes and the same.

In any case…. waste of money. I have wrote to the developer. NO response.

The problem is that I could not find a better OLM converter so far. It seems that all are pretty old nothing after May 2015 so my outlook 2016 file may have something that cannot be converted.

Doesn’t Work with Apple Mail 9.0

I bought this app today to convert Outlook 2016 files to Apple Mail. Outlook is wonky as anything with El Capitan. The conversion seemed to work. I had the fact that it created a separate mbox file for evey folder I have. Unfortunately, Apple Mail 9.0 immediately crashed when trying to open any of the converted mbox files.

Converts, but Mail 9.1 crashes during import.

I think the App converts olm files to mbox files, but unfortunately Apple Mail 9.1 is crashing when I try to import the files… Not worth the money.
