Personal Folders File (. PST)

A Personal Folders File (. PST) is a Microsoft Outlook file that stores data from emails, calendar events, and other items from a Microsoft Exchange mailbox. Storing the contents of an Exchange mailbox creates free storage space for incoming emails. This allows recipients to search emails and gives them the flexibility to design their own . PST system as per their needs, allowing them to organize their space the way they prefer it like combining inboxes or splitting folders.
