In Microsoft Outlook 2013 or later versions, you receive the following error message:
Errors have been detected in the file C:\Users\<name>\AppData\Local\Microsoft\Outlook\firstname.lastname@example.org
When you examine the application event log, you find an event with ID 2000 with details similar to the following:
Log Name: Application Source: Outlook Event ID: 2000 Level: Error Description: Database corruption was detected and the process was terminated. Process: "C:\Program Files\Microsoft Office\Office1x\OUTLOOK.EXE" (fb0.96c) File: "C:\Users\<name>\AppData\Local\Microsoft\Outlook\email@example.com"
Note The x placeholder in the Process path represents your version of Office (16 = Office 2016, 15 = Office 2013).
Corruption is detected in your offline Outlook Data File (.ost).
To resolve this issue, delete your .ost file and that you let Outlook re-download the information from the server that is running Microsoft Exchange.
Browse to the following location:
Find the .ost file that the error message reported to have errors, and then delete it.
In earlier versions of Outlook, we previously recommended that you use the Scanost.exe tool for errors that occur with your offline Outlook Data File (.ost). The Scanost.exe tool is no longer available starting in Outlook 2010. We now recommend that you delete your offline Outlook Data File (.ost) and that you let Outlook re-download the information from the server that is running Microsoft Exchange. For more information, see the following article in the Microsoft knowledge base.
