“I have carried some tasks on my Outlook OST file and upon completion, I moved forward to synchronize the changes to Microsoft Exchange server. However, before I could synchronize, my laptop got shut down due to software malfunction. Now, OST file fails to load and shows a message which exactly reads like ‘Failed to load OST file’. My friend has suggested me to run OST integrity tool. I ran that also but same issue is repeating. How can I resolve it?”

Like PST, OST is also a type of storage file in Microsoft Outlook that facilitate users to save emails, contacts, calendars, tasks, notes RSS feeds etc. One of the big advantage of this file is, it allows users to access information even when they are not connected to Microsoft Exchange server. However, when OST file fails to load, it becomes quite nuisance for the users as they lose access to entire information stored in OST file. But sometimes you can pinpoint the cause and solve it using built in procedure. Though manual method helps to resolve your problem in certain case, the issue still remains stable when OST file is corrupted.

Reasons why OST fails to load:

  • External Threats:If you get any spam email with an attachment then you should delete it right away without keeping on Outlook. If you open the mail and download the attachment then OST file might get damaged due to the viruses present in that mail
  • Improper synchronization:In case OST file synchronization is failed due to slow internet connection or unpredicted system shut down then Outlook will not load the contents of OST file
  • Forceful system shut down:Before shutting down your computer, you should click on the small arrow mark provided at the right corner of your Windows computer’s task bar and check whether any file is open from background. If you do not check it then Windows will intimate you about it before turning off. Ignoring the message will cause OST file to get corrupted leaving it in non-accessible state
  • Quitting OST improperly:Header is the important part which stores entire details of OST file. So if you don’t want to damage OST file header, then you should safely close Outlook using “Exit” option. Failing to use suitable option will damage header and it refuse to load its content
