All About OST Files And Recovery

About OST Files:

The acronym 'OST' stands for 'Offline Storage Table' files of Microsoft Outlook. OST files allow users to work in the off-line mode during the absence of connection to the Exchange Server. It means. if you use Outlook as your mail client and MS Exchange as the server Server client and currently face a server down time, you can still work on your Outlook mailboxes with the corresponding OST files.

How OST files work?

Whenever, you go off-line due to any reason, Outlook creates off-line folders (with extension .ost), which are the exact copies of your mailboxes on the Exchange Server. These OST files are saved onto your local computer and the mailboxes appear as if you are connected to the Exchange. When you connect to the Exchange Server, these OST files get synchronized with the Server and all the changes made to these files get reflected in the mailboxes on the Exchange Server.

This is how you can work on your Outlook even with unreliable or limited network connectivity. Apart from this, there are many situations, in which an OST file can be immensely helpful. Below are few among them:

Need of an OST file:

  • Mailbox has been deleted or migrated from Exchange Server
  • Exchange database has got corrupt
  • Exchange Server has crashed
  • Exchange profile has been modified or damaged etc.
