Where Outlook Stores Your Mail, Calendar, and Other Data

Microsoft Outlook stores your email messages, contacts, calendars, and other data as .pst or .ost files in folders that can be difficult to find. Here's how and where to look.

Instructions in this article apply to Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, and Outlook for Microsoft 365.

Go to the File tab.
Select Info.
Select Account Settings > Account Settings.
Select Data Files.
You'll find the location of your Personal Folders files next to each email account that is set up in Outlook.
Select an account.

Email messages for Microsoft Exchange, Microsoft 365, and Outlook.com accounts are backed up on your email server. In most cases, these types of accounts do not have Personal Folders files.
