Microsoft Office Outlook is one of the best and popular email client applications developed by Microsoft. It is mainly used as an email application, but it also offers multiple features like: calendar, task manager, contact manager, note taking, journal and web browsing. MS Outlook is a popular email client application therefore, it is commonly used in large organizations to send and receive emails and to manage them as well. But sometimes MS Outlook may create some troubles or it may work in an abnormal way. The main reason behind this unexpected behavior of MS Outlook is corruption. The data file, which stores all the email messages and other mailbox items of MS Outlook, has a size-limitation issue. The Outlook data file is known as PST or Personal Storage Table. There are two types of PST file: ANSI and Unicode. ANSI is used in older versions of MS Outlook and has a size limit of 2 GB. While Unicode is used in the newer versions of MS Outlook and has no size limit, i.e. up to 20 GB. In the higher version of MS Outlook the size limit increases by 50 GB. If a PST file crosses the size limit (mentioned above), then it may become inaccessible or corrupted. You cannot open an ANSI PST file in newer versions of Outlook and a Unicode PST file in older versions of Outlook. If you try such thing, your PST files become more susceptible to corruption.
Other than this, a PST file may also get corrupted due to several reasons, such as: virus attacks, abruptly system shutdown, sudden power failure, unexpected cancellation of Outlook, storage media malfunction, hard drive has bad sectors, human errors and many more. While opening a corrupt PST file you will receive an error message saying the file is corrupted or cannot be used. Some of the common error messages are shown below which may take place at the time of corruption:
- “Errors have been detected in the file Outlook.pst.”
- “The file Outlook.pst could not be found.”
- “Outlook.pst is not a personal storage folder file.”
- “PST has reached the maximum size limit.”
