All your Outlook data is backed up in the form of a PST file on your computer. As your Outlook mailbox grows over time, the PST file also increases in size. Say you receive an error ‘Mailbox is full’, you delete messages from the mailbox. But it is not automatically deleted in your PST file. The PST file is still oversized.

The large size of PST can cause corruption and hamper normal functioning of Outlook. Hence, it is a good idea to compact your PST if it exceeds a certain limit.
