Most commonly, the .pst files are acclimated to abundance archived items and the .ost files to advance off-line availability of the items.
The admeasurement of these files no best counts adjoin the admeasurement of the mailbox used; by affective files from a server mailbox to .pst files, users can chargeless accumulator amplitude on their mailservers.1 To use the .pst files from addition area the user needs to be able to admission the files anon over a arrangement from his mail client. While it is accessible to accessible and use a .pst book from over a network, this is unsupported, and Microsoft advises adjoin it, as .pst files are decumbent to bribery back acclimated in this manner.2
