Been curious about this since I've heard mixed experiences from people, some say conversions go fine, others end up missing emails or attachments afterward. Wanted to understand what actually causes it.
From what I've noticed, it usually comes down to the tool not fully supporting the source format, interrupting the process midway (closing the app, losing connection on large files), or using manual copy-paste methods instead of a proper export. I've been using Kernel Email Converter and haven't run into missing data so far, it processes the full mailbox in one go and keeps attachments and folder structure intact rather than requiring you to move things individually.
Still, I always test on a smaller file or a duplicate copy first before running a full conversion, just to catch any issues early rather than finding out after converting something important.
