    Yesterday, when I came back from my office in the evening, I decided to do my pending work. So, I opened my Outlook 2010 application on the system. As soon as Outlook opened, a pop-up appeared on my screen stating error has been detected in the file OST. I am seriously not getting what just happened in one night because before that it was working perfectly. Can anyone tell me what could be the possible reason behind it and how it can be fixed?

    Have you tried to run inbox repair tool (Scanpst.exe) to diagnose and fix the error manually? It is an inbuilt utility to deal with Outlook errors. Do not forget to close Outlook application before using this tool.

    Yes, I have tried it but it is unable to fix it. I am still facing the same issue, error has been detected in the file OST. Can you please tell me what could be the possible reason behind this error?

    Hi Sandradiaz
    There can be many possible reason behind it. Some of the major ones are:
    1. Outlook terminated suddenly when OST file and Exchange synchronization process is going on.
    2. Abrupt system shutdown during the synchronization process of Exchange and OST file
    3. There might be file system corruption
    4. OST file is virus infected

    There are high chances that you are facing error has been detected in the file OST message because of any of these reasons.

    As I can see that you have already tried scanpst.exe to fix the error, then it is clear that the issue is major or there is severe corruption in OST file. So, in this case, you can restore data from the backup. It is also one of the best methods of replacing corrupt OST file with the recently created backup file.

    While doing so make sure that you have recently taken backup of your OST file.

    I do not think so restoring OST file from backup is possible in all cases. Because most of the users do not backup OST file mostly as all data is stored on Exchange Server mailbox also.

    I think you should try to recreate OST file. To do so, follow the steps mentioned below:
    1. Find out OST file on the local machine.
    2. After that, select the folder and right-click on it and choose Properties option
    3. Then, you need to choose Clear Offline Items option
    4. Click on the OK button
    5. Then, start Microsoft Outlook application
    6. Now, click on the Send/Receive tab in your Outlook 2010 ribbon
    7. At last, click on the Update Folder option

    Now, as Outlook is synchronized with Exchange Server again, a new OST file is created automatically. I hope after this you will not see error has been detected in the file OST issue again.

    Hi Henry Davidson
    Thank you so much for explaining all major cause of this error. It let me understand my problem in a more clear way. But, before trying this recreating OST file method, I have few questions. Is it totally safe to delete old OST file and create new one? What about data stored in OST file? Will there be any loss of data? Because OST get corrupted before all changes updated in Exchange Server.

    Yes, there are chances of data loss if all modification are not merged with Exchange Server before corruption. If you want a perfect solution without any loss of data, then it is suggested to look for some trusted third-party tool.

    Data stored in OST file is really crucial for me so, I cannot afford loosing a single bit of information of it. Can you suggest me any software for the same that I can use?

    Yes, there is a wide range of software available but not every tool is best for you. Some of them virus infected, some results in loss of data. Therefore, be careful while choosing any of them.

    One of my friends tries Exchange OST Recovery tool and it works pretty well. It is capable to repair badly damaged OST file also in no time. Moreover, it also guaranteed no loss of data.
