This plugin can take a backup at regular intervals, and save it to the user-selected destination directory. It works when Outlook is closed, checks for the last backup date and triggers the copy process if necessary. Just before you do this, make sure to read on how you can make the files compact.
Automatically Backup Outlook PST Data File
Just before we start, Outlook can store data in two types of files– PST and OST files. While both formats can save emails, calendars, and contacts, OST is created when using IMAP or Exchange protocol, and PST is created when configuring a POP3 account. The biggest problem with OST file is that you can only reuse it at the origin computer, with the same email and user profile. It means that if you want to use it on another pc, it is not possible. So if you format your computer, you cannot use it. You can physically check the type of file by going to Account settings, and checking Data Files. Once you download the OutlookBackupAddin, install it. Make sure to have the .NET Framework 4.0 installed on your computer, and if you are using Outlook 2010 without a service pack, make sure to install VSTO runtime.
