It’s possible to split PST mailboxes into different files located locally or on a network driver. The problem is that although a network driver may seem like a local drive (drive mapping) network drive not supplies the same performance as a local one (i.e. C drive).

"The file F:\archive.pst is not a personal folders file."
(it is possible to replace the letter F with your own personal network drive letter).
