Additional Information
To run this tool smoothly on a Mac, follow the steps below:
The Problem: A company that has 200 employees wants to switch from Thunderbird to Outlook. Every employee has 4 MBOX files. This means the IT admin has to deal with 800 files and 600 GB of data. Handling this by hand takes 15 minutes for each file. This process would take 200 hours in total. About 30% of the data (180 GB) is older than 5 years, 8% of the emails are duplicates, and 5 power users have 25 GB mailboxes that are hard to open in Outlook.
The Solution: With MacSonik MBOX to PST Converter, the admin loads all 800 files in 1 bulk batch. The Date Range Filter keeps only the last 5 years, and Duplicate Email Management skips repeated emails, bringing the total to about 386 GB. Split Large PST Files divides each 25 GB mailbox into 3 PST files of 10 GB or less. No Outlook installation is needed for the conversion.
