Switching from Outlook for Mac to Thunderbird was easier than I expected with this software. I had several OLM files, and they were converted into MBOX format without mixing up the mailbox folders. The steps were simple enough that I didn't need any instructions. It also handled attachments properly during the export. The only thing I would improve is the interface, which could look a little more modern, but the overall workflow was smooth.
