I'm helping a client move from Outlook for Mac to Microsoft 365, and we first need to Convert OLM to PST before importing everything. While researching, I found MacSonik OLM Converter, and it seems to offer more than basic file conversion. Besides creating PST files, it can directly migrate OLM data to Office 365, Gmail, Yahoo Mail, Thunderbird, and Outlook, which could save a lot of time.

What caught my attention is that it supports complete mailbox migration, including emails, contacts, calendars, notes, journals, and tasks. It also claims to preserve the original folder hierarchy and doesn't impose file size limitations, which is important since the mailbox is over 25 GB. Another useful feature is the ability to split large PST files, making them easier to manage in Outlook.

Has anyone here used MacSonik OLM Converter for a business migration? I'm especially interested in knowing whether it maintained data integrity, handled attachments properly, and completed the process without errors. Any honest feedback or recommendations would be really helpful before I move forward with this project.

    If you're planning to move from Outlook for Mac to Office 365 on Windows, the first step is converting the OLM file into PST because Outlook for Windows doesn't support OLM files directly. I had to migrate an old Mac Outlook mailbox recently, and after trying a few options, the Softaken OLM to PST Converter worked well for me. It preserved emails, contacts, calendars, attachments and the original folder hierarchy without any data loss. The preview feature helped me verify the mailbox before exporting, and the conversion completed smoothly even with a large OLM file. I'd recommend trying the free demo first to confirm it meets your migration requirements.
