Why Corrupt OST and PST Files Need Recovery Software
Four facts about damaged Outlook data files and how OST Recovery Pro answers them.
- 1
OST Files Depend on Their Mailbox
An OST file mirrors a mailbox on the server. PCVITA software needs only the file, so orphaned files open without Exchange.
- 2
ScanPST Has Limits
Microsoft documents the Inbox Repair tool for PST files and suggests deleting an OST file for Exchange accounts. PCVITA software loads the OST file itself.
- 3
Deleted Items Hide in Damaged Files
Advance scan digs deeper and flags recovered deleted emails so you can spot them.
- 4
One Format Does Not Fit Every Job
Save to PST for Outlook, PDF for records, MSG or EML for other clients or Office 365 for a live mailbox.
Prepare Before You Recover an OST File
Six checks before your first recovery. Tick the boxes in order, then open OST Recovery Pro.
- Copy the damaged file to a safe folder. Work on the copy.
- Close Outlook and end any leftover outlook.exe process in Task Manager. Otherwise Windows reports that the OST file is in use.
- Find the file with Search File if you do not know where Outlook stored it.
- Collect certificates or keys with their passwords if your emails use S/MIME or OpenPGP.
- Check .NET Framework 4.5 or later on your PC.
- Test the free demo on your file before you pay. Download the demo edition and preview the items.
