Upgrade ANSI PST to Unicode PST
The Software has been smartly designed to upgrade Outlook client from any old version to the latest Outlook version. It can convert Outlook files which are saved in ANSI PST format into Unicode PST format with ease. By upgrading Outlook, you can increase the mailbox size limitation of PST files from 2 GB to 20 GB.
Convert Unicode PST to ANSI PST
Another function of this software is to downgrade Outlook client from the latest version to any older one. Older versions support ANSI format while Unicode format is supported by new versions. Switching back to any older version, i.e. 2002 or earlier, needs Outlook downgrade, and this tool will help you do that.
Converting multiple PST files at the same time is no more challenging. The batch conversion feature allows users to select multiple PST files at a time and perform conversion in just a single click. Just make sure all the selected PST files are of same format, i.e. ANSI or Unicode. Conversion of 3 ANSI and 2 Unicode PST files at a time can’t be done. Checkout this blog to convert ANSI PST to Unicode manually.
Don’t worry if you have no longer idea where your PST files are stored on your computer system. The auto-search feature of this software allows you to search your PST files on your system in an auto-mode. You just need to define the most probable location where you think the files are stored, and this tool will search them for you within a single mouse click. Read How to Fix Outlook Search Problem.
The "auto-log generation" feature of this software generates a log file at the location which will be shown before the conversion process will be completed. The log file which is saved in text format, contains all the information of PST upgrade or downgrade process.
Add PST to Outlook
Users can add new PST files to their Outlook profile directly from the software, no need to add them manually. Just before you can start the actual PST conversion process, you need to check Add new PST file(s) in Outlook profile box. You can use our Add Outlook PST Software as well.
Exclude Deleted Items
If you want to exclude the deleted items from the output PST files, you can check the "exclude deleted items" box before starting the PST conversion process. This feature will not save the deleted items of your old PST files into new file(s).
Remove Duplicate Items
Additionally, users can remove the duplicate items from their outlook PST files to make them handy and compact in size. Before the software can perform actual PST conversion, you can check Remove Duplicates in Outlook PST file(s) box.
It’s a non-destructive tool that executes the entire PST conversion process, i.e. ANSI to Unicode and Unicode to ANSI, in a safe mode. No changes or alteration is made on the original PST files. It maintains the Meta-data information throughout the operation.
The interactive user-interface makes this software convenient and easy for non-technical as well as complete novice users meaning that no prior technical knowledge is needed to use this software. Online video tutorials and snapshots would be helpful in this regard.
The Software supports PST files saved in both ANSI and Unicode formats and created by any older as well as latest version of Outlook.

PST Upgrade & Downgrade Has Become an Essential Task for Outlook Users. Why?
PST upgrade and downgrade are two different operations which are performed individually.
Upgrading PST means converting PST from ANSI to Unicode format. If you're upgrading Outlook from older to newer version, you must convert ANSI PST to Unicode. ANSI PST file is supported by Outlook 97 to Outlook 2002. PST file saved in ANSI format has 2 GB size limitation. To avoid this size limit and get more free space to store large mailbox, Outlook users upgrade their Outlook client. Though you can get maximum size of 20 to 50 GB by upgrading Outlook, but this doesn't provide you more space in your old PST files. You must upgrade PST files from ANSI to Unicode format to increase the size limitation.
Downgrading PST means converting PST files from Unicode to ANSI format. If you're downgrading Outlook from newer to older version, you must convert Unicode to ANSI PST. Unicode PST files are supported by Outlook 2003 and later versions. PST files saved in Unicode format have a size limitation of 20 to 50 GB which is fairly large. But sometimes, users need to downgrade their Outlook client due to any reason. You can't open a Unicode PST file in any older version of Outlook. To open a Unicode PST file in Outlook 2002 or any earlier version, you must convert it to ANSI format.
