How to Backup Outlook Data (Mail, Calendar, Contacts,Tasks) in Outlook 2016, 2013, 2010, 2007 or 2003

Last updated on July 5th, 2019

If you are using Microsoft Outlook as your personal organizer (Tasks reminder, Calendar, Mail application), then you have to backup its contents very often, to avoid loosing Outlook data when your computer crashes or if you want to transfer its contents to a new computer. 

First of all you must know that all Outlook personal folders are saved in one file on your computer (e.g. Outlook.pst) and if you backup (copy) this pst file to another location on your computer (e.g. your external USB disk), then you 'll have a reliable backup of your Outlook data.

Secondly, we should clarify that the most reliable and proper way to backup & restore Outlook data, is to manually copy/paste the Outlook data file (e.g. Outlook.pst) to another location instead of using the “Import / Export” capability given by Microsoft Outlook. This happens because when you are using Outlook's "Import/Export" capability to export Outlook data to a file,  you’ll lose significant Outlook settings like:

– Message rules.
– Junk E-mail and Blocked Senders,
– Folder and Items properties or views,
– Auto Complete cache (suggested contacts), etc.
