Free and easy splits Outlook storages into smaller parts using PST files. Just specify storage, target folder for PST files, each file’s maximum size, and the tool will divide your mailbox or any other storage into several parts. It is also possible to split your storages by year. Old ANSI and new Unicode file formats are supported for PST files created.
If you want your Outlook to perform fast and reliable, watch your mailbox and other storage sizes carefully. Separate your large Outlook storages into several parts of smaller size and you will notice the difference: smaller storages work faster and better. This utility creates new PST storages of smaller size, doesn’t make any changes to existing ones and retains all your data intact. Thus, if you don’t like the result, you can always revert back to you original unmodified storages. In addition to partitioning Outlook storages by size, partitioning by year is also available.
