Many users today are on the upgradation spree. They want everything upgraded because they don’t want to miss out on any new feature of the upgraded software. To avail the latest features, one has to get the advanced versions launched by the companies. Same is happening with Microsoft Outlook. Many Outlook users today are upgrading form MS Outlook 2000/ 2002 to 2003/2007. In a situation where you want to switch to a higher version of Outlook and need to upgrade PST to 2007 or 2003, Outlook PST conversion software is needed.

Besides other features of the latest Outlook version, the most luring one is the size limit. MS outlook 2003/2007 gives 20 GB space which is much higher than 2 GB given by MS Outlook 2000/2002/XP and earlier. For this many users want to convert outlook 2000 to 2003/2007 or Outlook 2002 to 2003/2007.

For Outlook PST upgrade, users have to look for outside sources because Microsoft, being the birth giver of Outlook, does not provide any PST upgrade tool. Unlike Microsoft, there are companies like SysTools that provide PST conversion software. It easily converts PST files. The older versions of Outlook support ANSI (American National Standards Institute) PST files and the latest versions 2003 and 2007 support Unicode PST files as well as ANSI PST files. So in order to upgrade Outlook PST files, a software is needed that converts ANSI PST to Unicode PST. SysTools PST Upgrade is the ideal solution to upgrade ANSI PST to Unicode PST having larger file size limit of 20 GB, which is something really imperative these days. The more space you have, the lesser it is.  

Besides PST upgrade, it also does PST degrade. Some people have this notion that there is no need for a PST degrade software because no one would ever perform the degrade function with any software. But, in a scenario where you have an older version (2000/2002)of Outlook at home and an advanced version (2003/2007) in office, then you need to degrade your PST to ANSI format as the Unicode format is not supported by earlier versions of Outlook. You should know that Microsoft does not support backward compatibility which means, upper version files cannot open in lower version but  in Outlook 2003, you can open both files, ANSI as well as Unicode. Also, the newer versions file formats are technically advanced than older version so new features are not supported by older versions. This is why user needs to degrade the PST file to ANSI file format as Outlook 2003 uses Unicode File format.

All this necessitates you to buy this SysTools software, whether you want to do PST upgrade or PST Degrade.

One important thing to note is that PST Upgrade software does not work with oversized PST files. If the file exceeds 2 GB limitation imposed by Outlook PST gets corrupted and Software does not work with corrupt PST file. So to preserve your PST files from corruption, immediately get PST Upgrade Software and rapidly upgrade ANSI PST files to new Unicode PST file format having 20 GB file limit size. You need to upgrade in order to safeguard PST file against corruption due to exceeding file size. Upgrading will lift the PST file size limit and you will easily avoid PST corruption.

This SysTools PST Upgrade Software is very user-friendly and converts all Outlook items including contacts, messages, notes, tasks, calendars, appointments and journals. It converts all mail folders such as Inbox, Drafts, Outbox, Sent Items, and Deleted Items. It smoothly runs on Windows 98/ME/2000/2003/XP/Vista. All email metadata remains intact after PST upgrade, means all information in the email properties like to, cc, bcc, dates and time etc is preserved. The software can convert ANSI PST File to Unicode PST File and also can convert Unicode PST File to ANSI PST File, means it is both, a PST upgrade tool as well as a PST degrade tool.  

In a nutshell, SysTools PST Upgrade Software is a complete tool for the Outlook users who want to switch in between the older and latest versions of Microsoft Outlook.
