Backing up your emails in Outlook

Outlook stores emails in a special proprietary database format called PST. PST files are very prone to corruption and data loss. For this reason we do not recommend using Outlook. If you are currently using Outlook, this guide will explain how to export your PST file for local backup. This file can then be saved to external media like flash sticks or external hard drives for on-site and off-site backup.

If you're using Imaginet's Stratus Cloud Backup service, you can back up your main PST file without having to export it, however it is still recommended that you crate local on-site and off-site backups as part of a 3-2-1 backup strategy.
