To free up some space on your Outlook Mailbox, you can utilize a built-in feature known as AutoArchive inside of Outlook.
A feature to automatically scan through the mailbox every N amount of days/weeks/months and the mails that has passed the period will be automatically moved into an archive folder that is in the form of a Outlook Data File(.pst). The .pst file will be automatically created and old mails will slowly accumulate there.
