Microsoft Outlook stores all your mail items (Emails, Contacts, Notes, Calendar Entries etc.) in a PST file and with every new email transaction, the size of the PST file grows. Depending upon the Outlook version, the PST file has a maximum permissible size limit and if the PST size exceeds beyond this limit, chances are there that it may get corrupt. A corrupt PST means, you cannot access any of your mail items from your Outlook mailbox. Hence, Outlook users are always advised to keep removing unwanted mails in their mailboxes from time to time.
