How Can I Make Outlook Data File Smaller?
A large PST file can make Outlook slower, especially when opening folders, searching emails, or loading attachments.
You can manually reduce the size by deleting unnecessary emails and attachments, archiving older data, or using Outlook’s Compact Now option. But these methods may not be suitable if you need to keep all your emails.
In that case, SysTools PST Splitter is a practical option. It can split a large Outlook PST into smaller files based on size, date, folder, or other criteria, while keeping the existing mailbox data intact.
If your PST has become too large, splitting it into smaller files can make it easier to manage and work with in Outlook. Always keep a backup of the original PST before making any changes.

You can make a large Outlook data file smaller by splitting the PST into multiple files. For large Outlook PST files, you can use GainTools PST Split Tool to split the mailbox based on size, date, folder, or other criteria while keeping the existing mailbox data intact.
I also found the bulk processing useful when dealing with multiple PST files instead of splitting each one separately. After splitting, I’d open a few of the smaller PST files in Outlook and check the folders, emails, and attachments to make sure the mailbox data was retained correctly.
