Sometimes you may wish to backup your email locally (on your laptop or home/office Desktop PC). This can be done just to ensure you have a backup copy, or maybe you are migrating your website to another server - either way it's a good idea to do occasionally.

4. Leave the default name in the Save Exported File As field as is or rename it anything you want like a 'Date to" for example. Click "Browse" to select the backup file location. You may want to save it in your 'My Documents' folder or on your Desktop so you can find it easily. Click "Finish."

3. Select Outlook Data File (.pst), and click Next.

   Or, you can select a specific folder to export, say Inbox. It's not possible to select multiple folders, so if you want to back up a few folders, you will have to repeat the process for each one individually.
   
   
   

5. The wizard will suggest saving a copy of your .pst file to the default location:
   C:\Users\<username>\Documents\Outlook Files\backup.pst

    

   If you are happy with that, simply click Finish.

   To save your Outlook backup to an alternative place, click the Browse button, select the desired location, and click OK.

   If you are exporting to an existing .pst file, choose the desired option for duplicate items. The default Replace duplicates with items exported works fine in most cases.
