Engineer Analysis

Outlook stores data in PST or OST files, depending on account type. Partial email loss often results from synchronization conflicts with Exchange, IMAP servers, or local client errors. Professional engineers, such as those at Jiwang Data Recovery, analyze file integrity, server retention policies, and examine backup snapshots to restore missing emails. The feasibility and success depend on how long the emails have been missing and whether they have been overwritten or permanently deleted. www.sosit.com.cn

Common Causes of Missing Emails

• Synchronization failures between Outlook client and Exchange/IMAP servers.
• Corrupted PST/OST files caused by software crashes or improper shutdowns.
• Emails accidentally deleted or moved to unexpected folders.
• Retention policies on the server automatically removing older messages.
• Interference from third-party add-ins affecting message storage.

4. Restore from available PST/OST backups if the client files are corrupted.
5. Engage professional recovery servs to extract lost emails from corrupted or partially overwritten PST/OST files.
6. Verify recovered emails for completeness and attachments.
