What Our OLM Converter Customers Are Saying.
IT Manager
Paralegal
I needed individual emails as EML files for a legal document request. I was able to export just the specific emails I needed, instead of the whole mailbox. This tool saved me hours.
Digital Forensics Consultant
I needed to preserve OLM data with full metadata intact as part of an e-discovery request. The preview feature of the OLM file converter lets me verify integrity before exporting for the case file.
Small Business Owner
I'm not a technical expert, and I was hesitating converting my old Mac Outlook archive. The whole process from preview and select to export took about 15 minutes and I did not need any help.
I tried two other OLM converters before this one. This was the only one that handled our largest mailbox without crashing. Also the support answered my question within the hour.
I just recently used the trial version with my OLM mailbox and tested the filters and final results. Now, I can say that upgrading to the licensed version is now an easy decision.
The best thing about this OLM file converter tool is the speed. This software has helped me convert years of OLM archives in an hour. I am fully satisfied with the performance of this software. A big shout out to ForensikSoft.
