Though Microsoft doesn't provide anything to merge PST files into a single file and to split PST file into multiple parts, but still there are few built-in features and functions in Outlook client which enable you to do that. As Outlook is the only thing you needed for this, it would be free. There's no need to purchase any paid solution. I've shared a couple of blog posts below in which you can find complete information:

You must try the manual tricks given in the above blog posts before using any paid software.


I have used SysInfoTools PST merge Tool and truly speaking I really liked the way it merged my large Outlook files.
