Free and simple software splits Outlook storage into smaller PST files by specifying storage, target folder, and max file size. Also allows for splitting mailboxes and other storages by year.

What's great about Free and Easy is that it also supports partitioning your storages by year. You can choose to split your old ANSI and new Unicode file formats for PST files created. When it comes to Outlook performance, it's important to keep an eye on your mailbox and storage sizes – and this software makes it easy for you to do that.
By separating your larger Outlook storages into several parts of smaller sizes, you can expect a noticeable difference with faster and better working storages. Free and Easy creates new PST storages of smaller sizes while leaving existing ones intact, ensuring that all your data remains safe and secure.
This utility is particularly useful because it enables you to revert to your original, unmodified storages if you're not happy with the result. In addition to partitioning Outlook storages by size, you can also partition them by year, giving you more flexibility in managing your data.
Overall, Free and Easy is a user-friendly and effective software that makes managing your Outlook storages a breeze. Whether you need to split by size or by year, this tool is sure to come in handy.
