Thanks. We'll let you know when a new response is added.

To recover items from a corrupted PST or OST you can try to repair either file type using ScanPST.exe or ScanOST.exe. For Office 2000, XP, and 2003, these 2 exe’s are located in C:Program FilesCommon FilesSystemMSMAPI1033; for Office 2007 – %drivefolder(that you installed Office into)%Office12.

To recover hard deleted items from the online mailbox (assuming you’re using Exchange), you can turn on the “Recover Deleted Items” feature for Outlook using the registry. In Regedit, go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftExchangeClientOptions , then create a new DWORD Value in there named DumpsterAlwaysOn (case sensitive, I think) – give it the value of 1.
