I recently found an old OLM archive from a previous MacBook that contains several years of emails and attachments. I no longer use that Mac, but there are some important conversations in the archive that I need to access again. I’m considering converting the OLM file to PST so I can open the data through Outlook on another system, but I’m not sure which converter would be reliable for this kind of old mailbox.
I’ve seen MacXTools OLM Converter for Mac mentioned while researching different options. Has anyone actually used it with an older or large OLM file? I’d especially like to know whether it preserves the original emails, attachments, folder structure, and other mailbox details during conversion. Also, are there any things I should check before converting the original OLM file?
