This article contains a step-by-step guide to backing up hosted microsoft exchange accounts using Outlook. Although this guide was prepared using Outlook 2013, the steps are nearly the same for Outlook 2007 and Outlook 2010.

The contents of this article only apply to hosted exchange email accounts. For standard email accounts, see Backing up mail accounts


To complete the steps in this article, the following items are required:

  • Outlook must already be configured to access the target account.
  • For improved performance and reliability, it is recommended that Outlook has completed folder synchronisation. If the account has only just be configured in Outlook, good practice is to let Outlook to fully synchronise all messages and folders priors to creating a backup.
  • Sufficient space to store the backup files. Hosted Exchange accounts may be upto 125GB in size, so backup files will be of an equivalent size.

Important Information

  • The time required to backup your mailbox will depend on a number of factors including the speed of your Internet connection, the size of your exchange mailbox and the performance of your computer.
  • You will not be able to use Outlook whilst a backup is being created. If your exchange mailbox is many gigabytes in size, the backup process may take several hours to complete.
  • During the backup process, you may still access your account using Outlook Webmail. Using Webmail should have no detrimental affect on the backup process.

Storing Backups

Where and how a backup is stored is just as important as its' creation. Ideally, backups should be stored on a resilient media in a separate and secure geographical location. If this is not possible, backups should not be stored on personal computers but on a secured storage device.
