Your PST file is oversized? Whenever the PST file reaches or exceeds the limit, you will not be able to open or load it any more, or you cannot add any new data to it. This is called oversized PST file problem. More detailed information can be found at
You can use Outlook recovery tools to solve the problem. Below is a list of them:

Microsoft Outlook gives you the option to compact .pst files. Here’s how you can do so:

• Click ‘File’ on the toolbar and click ‘Data File Management’.
• Click the folders you want to compact and click ‘Settings’.
Note: For Windows Vista and Windows 7, the default path of .pst files is drive:\Users\user\AppData\Local\Microsoft\Outlook. For Microsoft Windows XP or Microsoft Windows Server 2003, the default path of .pst files is drive:\Documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook.
• Click ‘Compact Now’, click ‘OK’, and then click ‘Close’.

If you want to reduce the size of the inbox, you can use the ‘Mailbox Cleanup’ option on the ‘Tools’ menu.
