Easiest Tutorial to Backup Outlook Cached Email Addresses

About Outlook cached email addresses

When you compose an email in Outlook, the email addresses of the recipients are automatically filled in based on previous emails you've sent or received. Outlook will save the auto-complete cache automatically, and then list the auto-complete cache when you type related letters in the To/Cc/Bcc field in email as below screenshot shown.

This can save you time and effort. However, these cached addresses can be lost if you delete your Outlook profile or if you configure a new computer, which means that if you lose your cached email addresses, you'll need to manually enter them all again.

Therefore, it is important to backup your cached email addresses to make sure you can still access them if anything happens to your Outlook profile or computer. If you are needed, continue reading the following content for more details to finish the task.
