Effortless Way to Split Large Outlook OST Files

Managing oversized Outlook OST files can be a challenge, especially when they begin to affect email performance and risk data corruption. DRS Softech OST Splitter Tool is a professional utility designed to split large OST files into smaller, manageable parts without compromising data integrity. Whether you’re an IT administrator, a corporate professional, or an individual Outlook user, this tool simplifies the process of dividing OST files based on size, date, sender, or folder, ensuring faster performance and enhanced manageability.

What is an OST File and Why Do You Need to Split It?

An OST (Offline Storage Table) file is created by Microsoft Outlook when connected to Exchange Server, allowing users to access their emails, contacts, and other data offline. Over time, as email communication increases, the OST file grows in size and can become prone to corruption. A large OST file can slow down Outlook's performance and may lead to issues such as unexpected shutdowns, data loss, or inaccessibility.
Splitting an oversized OST file is one of the best ways to prevent these issues. The DRS Softech OST Splitter Tool helps break these large files into smaller, more manageable segments without affecting the original data structure or content.
