Nowadays, Most of the users want to access another user OST file as received from client or from organization. So, we have written this article to share the process to easily open another user OST file by manually and using OST to PST Converter.

Microsoft Outlook is one of the most used desktop email clients. It contains its mailbox data in OST and PST file. OST stands for offline storage table; it allows access to mailbox data without connectivity. 

Reasons to Access Another User OST File

  1. When a user's Exchange or Microsoft 365 account is deleted or deactivated, the OST file might still reside on their computer. Accessing the OST allows recovery of emails, contacts, calendar entries, and other data not yet backed up.
  2. If a user is moving to a different domain, mailbox, or email system, administrators may need to access the OST file to convert or transfer their existing data.
  3. Organizations may need to access a user's OST file as part of internal audits, legal investigations, or regulatory compliance reviews. This must typically be authorized by HR, Legal, or IT security departments.
  4. If a user's Outlook profile becomes corrupted and cannot connect to Exchange, the OST file may still contain recent data. Accessing the OST can help restore this information.
  5. In cases where Outlook is not syncing with the Exchange server or some data is missing from the server, the OST file might contain unsynced emails or calendar items that need to be retrieved.
