Hi @Shanaya S ,
Welcome to our forum.
About how to repair Outlook .pst file, you can fully check the link @Ramsyfish mentioned above.
By the way, in order to better help solve your issue, May I know what specific operations did you do before receiving this error? I tried some research about the error you provided above and found some common workarounds like below:
- Errors like that might happen if the “Read-only” attribute has been enabled in your file properties. So, please ensure that “Read-only” attribute is not selected and then try again to see if the issue could be resolved then.
- Besides, to confirm if there is something wrong with this specific .PST File, it is also suggested for you to copy the .PST File to other devices to test and see if the issue could also be reproduced there.
For more information: The file PST is not an outlook data file (.pst). (Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Hope this can be helpful.
