An OST file, short for Offline Storage Table, is a data file used by Microsoft Outlook to store a copy of your mailbox information.

OST files ensure that you can access your data seamlessly, whether you’re online or offline.

Why Need to Open an Outlook OST File?

We all know that Outlook stores its data in two common file types OST and PST. When you configure an Exchange account, IMAP, Office 365, or Outlook.com email account in Microsoft Outlook, an Outlook OST file is generated. This file establishes a connection with a specific Outlook profile and is automatically encrypted using the MAPIEntryID GUID key.

However, if the user profile is deleted or the mailbox is disabled on the server, the OST file linked to that profile transforms into an orphan, rendering it inaccessible. Consequently, you cannot open, import, or access it directly within any other Outlook profile or account.
