The user’s system is where the OST file is kept. But where and how to Locate OST files in Outlook becomes very important. Users sometimes have so much doubt that they only want to open OST files if it’s the last minute and they need to. When this happens, the user starts looking for possible places where the OST file could be. In the meantime, inexperienced users tend to delete the real files instead of the old ones when looking for the missing OST file.

Why is it important to know where the OST file is?

When an Outlook user might feel the need to find the exact location of the OST file is the following:

  • When an OST file needs to be backed up (and the Import/Export wizard isn’t available).
  • If the OST file location needs to be changed because of storage problems,
  • When an OST file is corrupted, a new one must be made when an OST file needs to be converted to a PST file.
  • If Exchange Server is down or being worked on when an OST file needs to be analyzed.

Is it that simple? This question comes to mind when the user wants to find the OST files. So, the quick answer to any user who asks this question is, “Yes, it’s easy to find the OST files and make the changes you need.” But there is a catch: “The OST file location may be different depending on the version of MS Outlook being used.”

By the way, here are where you can Locate OST files in Outlook versions on the system stored by default:

For most versions of Windows, it’s C:.Users\AppData\Local\Microsoft\Outlook

For each Outlook version, here are the default places where the OST file is kept.


Outlook 2013 and latest:  C:\Users\admin\AppData\Local\Microsoft\Outlook

Outlook2010: C:\Documents\Outlook Files

Outlook 2007 & older versions: C:\Users\User Name\AppData\Local\Microsoft\Outlook

Windows XP: C:\Documents and Settings\Local Settings\Application Data\Microsoft\Outlook

Users of any version of Microsoft Outlook can use the Account Settings feature to find an OST file on their own.
