How to Recreate OST file in Microsoft Outlook 2007/ 2010/ 2013/ 2016

If users are not able to preserve their current OST files with Microsoft Outlook, they will need to reset or recreate their OST files if they cannot restore the original database. OST files can be recreated by downloading a copy of Exchange mailbox items again.

Also known as Offline Storage Table file, the OST file is created by Outlook to store copies of emails from the Exchange server. In this way, if the users cannot connect to the Internet for some reason, they can continue working on their mailboxes in Cache mode. When the connection to the Internet resumes, the OST file is synchronized with the mail server and the changes are uploaded.

The OST file is fairly important. With an extendible capacity of up to 50 GB, users can save as much data as they wish to access while being offline. It also helps to recover lost mailboxes in case there is any damage to the Exchange server. Depending on the version of the Windows operating system, the OST file is stored in different locations.

Although the benefits of the OST file are remarkable, there are quite a few disadvantages too. For instance, if your account profile has been compromised, the OST file will be of no use and recovering it would be futile. And if the OST file itself becomes damaged, its recovery process can be very time consuming.

Primary Reasons behind OST file damage

There are multiple reasons for an OST file to get corrupted. And once this happens, they become completely unreadable. The following are some of the hardware as well as software reasons that could corrupt an OST file:

• A power outage during the synchronization of the files
• Unclean termination of a session in Microsoft Outlook
• The storage files have reached their capacity
• A virus in the system
• Network issues during the synchronization of the files
• Bad sectors in the hard drive
• Issues and bugs in the Microsoft Outlook application
• Issues and bugs in the storage device
