How to Resolve Error 15003 of Microsoft PST File?

With Microsoft Outlook, all your emails, contacts, calendar entries, and tasks are saved on your computer. The Outlook mailbox items that are saved on your computer are stored in Outlook Data File, which is known as Personal Storage Table (PST) File. If you are using Microsoft Exchange account, then all your mailbox items are delivered and stored on the mail server. On the other hand, when you use IMAP, POP3, or web based email account, then your mailbox data is stored on your computer in PST file.

The PST files have size constraint that varies with the version of Outlook. Outlook 2002 and early versions support PST files of 2GB, whereas the later versions (Outlook 2003 and later) support PST files up to 50GB. Due to their complex structure and their location on local hard drive of your computer, PST files are prone to corruption. Generally, a corrupt PST file throws an error message when you try to extract data from it or try to access it. A practical example for this situation can be a better way to understand it:

outlook repair pst

An error message that a corrupt PST file throws while trying to access data from it is:

“Error 15003 when processing PST files”

This error message normally maps to MAPI error 0x80040600. The error number 0x80040600 says

MAPI_E_CORRUPT_STORE, which means corrupt PST file. The corruption of PST file occurs due to various reasons, which vary from PST structure corruption to issues with local hard drive. Since in most of the cases, the Inbox Repair Tool of Outlook resolves your problem, using this tool for such situations can also be beneficial.

The Inbox Repair Tool is the inbuilt utility of Outlook that diagnoses and repairs errors in Outlook PST file. It scans the file to make sure whether the structure of the file is intact or not. If it is not, then the tool resets it and rebuilds the headers. The tool works efficiently with Outlook 97 to 2002 PST files, Outlook 2003, and Outlook 2007 both. However later version like Outlook 2010 & 2013 are not supported fully by this tool.

It is installed with the installation of Outlook and is located at:

“drive:\Program Files\Microsoft Office\OFFICE12.”

Use the following steps to repair and resolve the error (including the above mentioned one) with this tool:

• The very first step is to exit Outlook, if it is running.
• Double click the scanpst.exe file (the Inbox Repair Tool is found in this form only).
• In the box ‘Enter the name of the file that you want to scan box’, enter the name of the PST file that you want to scan; or you can browse for this file for checking it.
• For specifying the scan log options, click ‘Options’, and then select the option that you want.
• Click ‘Start’.
• If you find errors after the completion of the scanning process, then you will be prompted to start the repair process for fixing the error. Note: A backup file of your PST is created during this process. For changing the name or the location of this file, click ‘Enter name of backup file’ box, enter a new name, and ‘Browse’ for the location where you want to save it.
• Click ‘Repair’.

With these simple steps, your PST file will be repaired; however, if this process too fails to do any needful to you, then use of a professional PST recovery tool is recommended. A reliable tool repairs corrupt or damaged PST file and restores all its data without causing loss. One such tool is Stellar Phoenix Outlook PST repair.
