Information, tips and instructions

Open PST File

A PST file is a personal storage directory in which copies of your email messages, calendar events, rules, signatures, and even Microsoft Outlook interface settings are stored. In versions of Outlook 97 through 2002, the storage limit of a PST file for a user is 2 GB. As of Outlook 2003, the limit is 20 GB. It is not recommended, under any circumstances, to try to modify a PST file or move it to another location as errors could occur and it would be necessary to recreate it from Outlook.

Knowing this, you can easily see how important it is to make a backup of these files periodically to keep them protected and secured. Imagine that you are going to check your calendar and realize that it has been damaged and does not have a backup version. That is why it is vital that you make a backup of your PST files.

A very simple way to protect yourself against such a situation is to back up your PST files in an external storage unit at periodic intervals. This also helps to free up valuable mailbox space. These simple steps will help you make sure you have a recent backup to turn to in case a file gets damaged or suddenly disappears.
