Thanks. We'll let you know when a new response is added.

The PST files are Outlook personal storage table files. The size of PST file can be increased and decreased through PST Converter Software tool. 

The tool increases the PST file size by converting it from ANSI to Unicode PST format. 
In the same way the tool can downgrade a PST file by decreasing its size. This can be done by converting Unicode PST file to ANSI PST file format. 
The PST upgrade and downgrade tool smoothly performs the upgrade and downgrade of PST file.This tool is compatible to all Outlook versions like Outlook 2000, 2003, 2007, 2010, 2013 and 2016( 32 and 64 bit).

    If the file has already gone over the 2gb limit and your using the older ANSI format then there is only one solution I can think of that you can do with that PST, cut it down using Microsofts PST crop tool. It's a long tedious process, I've done it many times, and you will lose some emails but you can recover most of the emails.

    Rename this pst and a new pst will be created that will be blank. Add the renamed pst to your outlook.
