Microsoft Outlook is one of the most popular emailing solutions on the market. In fact, it’s right behind Apple’s Mail and Google’s Gmail. As the name suggests, Outlook comes from one of the most recognizable brands in the world of IT – Microsoft.
There is one thing that is difficult to do with Microsoft Outlook though – many users find it hard to back up Outlook OST files. Below you can find three proven methods to back up an OST file and why you should do it. First, let’s see what exactly OST files are.
What Are OST Files?
Every software you use stores files on your drive under a specific extension. Some tools have entire extension lists. Microsoft Outlook is one of those tools which saves files under a range of extensions, and one of those extensions is .OST.
Now, the purpose of the OST file is to enable one specific Outlook capability. Thanks to OST files, you can continue your work in Outlook even when your Internet connection drops. If you have a slow or unstable internet connection, this Outlook’s feature enables you to use it efficiently.
Once the internet connection is established, the OST file connects with the Exchange server and synchronizes with the inbox.
