How can I clean up my Outlook mailbox?
TreeSize shows you how much space individual mails and their attachments in your Outlook mailboxes take up on your hard disk.
Scan all included mailboxes at once or just subfolders like the inbox or the spam folder. You'll find space wasters in no time!
Analyze mailboxes
TreeSize can scan and analyze locally stored Outlook mailboxes like every other storage system.
Clean up easily
Clear diagrams, a list of the largest emails or even a distribution by age of the mails help to tidy up the mails.
Easy setup
TreeSize automatically accesses all included mailboxes - start scanning immediately.
