Hi everyone,

If you're dealing with large PST files and you want to split them into smaller parts, I would personally suggest Stellar Splitter for Outlook, an MVP recommeded tool. It is easy to use for both system admins/subject matter experts and non techy persons.

Here's how to use it:

First, download and install Stellar Splitter for Outlook.
Open the software and choose the PST file you want to split.
Decide how you want to split it – by size, date, or folder.
Choose the destination where to put the new splitted PST files.
Click on "Split," and let the tool split the files!

The best thing about Stellar Splitter for Outlook is it maintains the folder structure while splitting and it keeps all your data safe and it supports all Outlook versions.
