Outlook is part of your daily routine. You use it to send email messages, to set up calendar events, and to create tasks and other items. But do you wonder how and where all those items are stored?
For Microsoft 365, Exchange, and Outlook.com accounts, all of your information is stored on the server, but an offline copy is also stored on your local computer in an Offline Outlook Data File (.ost). For POP and IMAP accounts, you might store your Outlook items in an Outlook Data File (.pst).
