How to Access Another User OST File?

Do you want to open and read data from another user’s OST file? Then read this guide to know the process to access another user OST file manually and using OST to PST Converter.

OST files are profile-specific and cannot be opened directly by another Outlook profile or user. If you try to open an OST file belonging to another user, Outlook will show errors. To successfully access the data inside another user’s OST file, converting it to PST is the most effective solution.

Microsoft Outlook is one of the most widely used email clients as it allows for sending and receiving emails for both personal and professional purposes. It stores user mailbox data in OST and PST file formats. OST files include emails, contacts, tasks, calendars, journals, and more, allowing offline access. However, due to the encryption and profile binding of OST files, they cannot be accessed directly by another user or on a different system.

Reasons to Access Another User OST File

• Accessing another user’s OST file allows recovery of important business emails and contacts.
