To get rid of large files that may be taking up the majority of space used by your mailbox, open the “Search Folders” tree in your folders list as shown below and select “Large Mail” or something similar.

Once your “Large Mail” view is open, you will see messages grouped by Size categories (Enormous, Huge, Very Large and Large). Review and save the attachments you want to your My Documents or a network drive, then remove the attachment from the email.

How to remove an attachment

1. Select an email

2. Right click on the attachment and chose Save As

3. Save the attachment to your My Document or network drive

4. Right click on the attachment again and chose Remove Attachment
