Going in the Details" Outlook Email Application: MS Office Outlook, the email utility tool, is a widely used one, which is extensively utilized by a plethora of online users, throughout the whole length & breadth of the world, for many different emailing operations, chiefly to send/receive emails for communication purpose. Its personal storage folders or the personal stores are the files with .pst extension. Outlook PST Files: These PSTs are basically the local copies of all the data (emails and other) fed in the Outlook mailbox. So, basically these are the Outlook data storehouses. These Personal Storage Table files or PST files are encoded either in ANSI format (as in older versions of Outlook) or Unicode format (as in the newer Outlook versions). ANSI PST Files Now, coming to the older versions where PST is stored in the ANSI format that limits you to store the data beyond 2GB as this is the threshold limit for data storage in ANSI PST, beyond this limit or when the file size crosses this point of 2GB, Outlook PST corrupts. This format is mostly used with MS Office Outlook program versions 97, 2000, and 2002. Unicode PST The data storage in Outlook improved as Outlook got upgraded to version 2003, wherein the data storage limit was increased from a meager 2GB to up to as large as 20GB. The format of files used to store data now started to be called as the Unicode file format with much higher data storage threshold limit. This gave chance to Outlook users to store more and more data in their personal stores. This facilitated a user-defined file size that can go to a maximum size of 20GB. PST File Corruption Even so the file size increased in Unicode files, still the issues with Outlook program launch, crashing of Outlook, non-opening of PST, and data inaccessibility still showed up with newer Outlook versions too, just as the users used to face these issues with older Outlook versions. These behaviors mainly account to PST corruption, which is a problem common to all versions of Outlook, whether new or old. Your Situation: You try to launch Outlook and it does not respond.
