MS Outlook 2003 is a versatile email client used on stand alone as well as network computer. Emails and attachments are stored by MS Outlook in two file formats i.e., .OST and .PST. OST or offline storage table is created when MS Outlook is disconnected from Live Exchange server. On the contrary, PST or personal storage table is created when you add a new email account in MS Outlook. OST or PST file created with MS Outlook 2003 can store emails and attachments up to 20 GB size. When OST file of Outlook 2003 mailbox crosses the 20 GB size limit, it fails to synchronize with MS Exchange server. As a result of OST file non-synchronization, different error messages are displayed on the computer screen:
Microsoft has added inbuilt tools scanpst.exe and scanost.exe in MS Outlook 2003 to check the OST file for oversize and other corruption issues. Default location of both scanpst and scanost is:
Scanpst.exe fixes oversize, data integrity and other issues of both OST and PST files. You can repair and recover corrupt OST file with Convert OST to PST file of your Outlook 2003 mailbox in following steps:
