What are the right ways to split PST files?

There are two ways to split PST files

Method 1: Archive Features

1. Outlook → File → Info → Tools → Clean Up Old Items
2. Archive by Date → PST will be separated into smaller parts.

Limitation:

Date-based split only. There is no size/folder/year-wise control.

✔ Method 2: Move to New PST

1. Create a new PST file
2. Shift emails by manually dragging and dropping.

Limitation:

It takes a lot of time, and there is a chance of data loss.

✔ Method 3: Import/Export Option

1. File → Open & Export → Import/Export
2. You can create a new PST by exporting specific folders.

Limitation:

Size-based split is not possible. Repetition and duplicates can occur.
