Is It Important to Backup OST File from Outlook? How Can We Do It?
Microsoft Outlook, one of the most liked email applications among professionals, creates two types of data files. One is an OST and the other is a PST file. These files are stored in your system and store your important Outlook data. Thus, many users have queries like if they need to backup OST file or not. If it is important, then they can do it.
So, this article gives you detailed information on the importance of OST file backup and the easiest solution to do it. However, before that, a few users know about the differences between OST and PST files. So, those users can find that out below.
Outlook creates two files as its repository to store its mailbox data i.e. OST and PST file. The OST (Offline Outlook Data File) is created when you configure your email account using IMAP configuration or when configured with Microsoft 365, Exchange and Outlook.com accounts. Whereas, the PST (Outlook Data File) is created when you configure your mail account via POP configuration.
Reasons Why Should Backup OST Files on Your System
- OST files contain a copy of your Exchange mailbox items. The information stored is very important and so, cannot be ignored. It becomes essential for users to take backup of it.
- There might be chances of accidental or mistaken deletion. Once the data is lost from the Exchange server, and it syncs with the OST file, then it would be lost permanently.
- There is a possibility of data corruption as well where the OST files get corrupted. So, time to time backup is required so as to prevent data corruption of OST files.
After discussing the reasons, let us now discuss the best and secure ways to backup OST files.
