      If Outlook runs smoothly now and there is no connection issue, and you are still unable to access Outlook data, your cache file (OST) is corrupt. There are different fixes you can try to fix the OST file corruption.

      1. You should delete the OST file from its location and create a new one.The new OST file will be free of corruption and will help you access your emails again.
      2. Another troubleshooting option is to run Outlook in Safe Mode. Go to the Search option and input ‘outlook.exe /safe.’ If Outlook works fine, then you should find and remove problematic add-ins from the Outlook application.
      3. Another method is to trace route your proxy server. Input the command tracert hostname in the Command Prompt, and it will enlist the connections with Exchange. If there is a problem with the network connection, then such services will load slowly. In such a case, you should contact your Internet Service Provider.
    • Fix Exchange Server Issues
      By using all these troubleshooting methods, you can confirm the root of the error and rectify it. But, if the problem is due to the corruption in Exchange data, you will have to scan the database file using the ESEUTIL tool and remove the corruption. But, you should also know that the ESEUTIL tool may further delete the data if you perform the hard recovery. That’s why you should go for a secure option that removes the corruption and saves the data.

      To fight corruption in a faulty EDB file, you should trust Exchange Server Recovery software that can recover the mailboxes from any corrupt state. It can easily remove the problems linked with Exchange 2010 dismounted database files. Additionally, you can save the recovered data in the offline PST, live Exchange Server, Microsoft 365, Public Folder, and other destinations. There are also several output formats where the EDB file’s data can be saved. It protects the data integrity and collects the data in a consistent format so that you can access the files as they were saved earlier.
