the most amazing customer service ever

I bought this app on the basis of the description and the customer rave reviews. Problem was, my Outlook was broken and it would not rebuild my Main Identity. The file was corrupt. This had happened before so I was ready to throw in the towel and try to move to apple Mail. But the app didn't work. When I emailed then phoned Gladwev for help, they told me I really needed their database recovery app, “Outlook Mac Database Recovery” app instead, but they also screen shared with me and rebuilt the whole thing for me! Absolutely top notch customer service! All I had to do was pay the difference for the second app and watch the magic happening. They were screen sharing with me for at least 1.5 hours, and it was 2 am in India. I cannot recommend them highly enough! Now that Outlook is fixed, I may use the other app to migrate to Apple Mail but it is no longer so necessary. When I do get around to switching, I’ll use them, be sure. Thanks guys!

Worked quickly and accurately

Have been using Mac Outlook 2011 since, well, 2011. My mail database was relatively lean though. Still I didn’t want to just chuck all of that stuff since I kept it for a reason. This App did what was advertised, quickly, accurately and with minimal muss and fuss. A PDF even popped up after it was done running with pointers on how to get the converted stuff into Apple Mail. Those directions were about 85% correct and I was able to work my way through the misstep that was published there. Could be that there are some OS differences that made the directions seem like they weren’t quite right since I am still running High Sierra. Really looking forward to being able to say goodbye to Outlook for good now. Price we reasonable compared to other OLM converter software.

Great Product

My Outlook stopped working for some reason, so I thought it's time to change to Mail on my MacMini. This software worked perfectly to convert my .OLM from Outlook over to Apple's Mail. All of my Folders from Outlook .OLM were converted perfectly to an "Import" Folder in Mail. This software is well worth the small fee. Thanks Apple!!!
