This is a great point to bring up. I've noticed that once MBOX files exceed a certain size, even basic searches within the mail client can become incredibly sluggish. Keeping files manageable by splitting them is definitely a better long-term strategy for data integrity than just letting them grow indefinitely.

Hi everyone,

If the MBOX file is really large, I’d avoid manually splitting it because that can get messy and there’s always a risk of damaging the mailbox structure. I came across SysTools MBOX Splitter while looking for a safer way to handle oversized MBOX files. It can split MBOX files based on size and lets you keep the resulting files more manageable without changing the original data unnecessarily.

It worked well for my use case, especially when the mailbox was too large to open or process comfortably. I’d still recommend keeping a backup of the original MBOX before splitting, regardless of which tool you use.
