Troubleshooting Outlook OST errors
If you use Microsoft Outlook as your primary email client, you may have encountered the error message ‘Errors have been detected in the OST file’. This error message can be frustrating and can prevent you from accessing your Outlook data. The OST file is a critical component of Outlook, and when it becomes corrupted or damaged, you may experience problems when using the software. In this blog post, we will explore what causes this error, its symptoms, and how to fix it.
An Offline Storage Table File (.ost) is a local file that Outlook stores on your computer when you set up an Exchange email account on Outlook. The OST file is synchronized with the mailbox server and enables you to access your emails, contacts and other mail items even when a connection to the internet is not available.
Now, when you try to access your email account on Outlook, you may get the following error message:
Errors have been detected in the file C:\Users\Username\AppData\Local\Microsoft\Outlook\username@email.com.ost. Quit Outlook and all mail-enabled applications and then use the Inbox repair tool (Scanpst.exe) to diagnose and repair errors in the file. For more information about the Inbox repair tool, see Help.
