I have been facing an issue with Microsoft Outlook where it keeps freezing and becoming unresponsive whenever I open or work with my mailbox. After checking, I realized my PST file size has grown quite large, and I suspect that might be the reason. Can anyone explain why Outlook struggles with oversized PST files and what steps I can take to fix this issue? Also, are there any reliable methods or tools to reduce or split the PST file without losing emails?

Recently, I was facing a big problem; the size of my Outlook PST file had increased to more than 15GB, and Outlook used to freeze every time. I tried many methods on the internet, but could not find any permanent solution. Then I came to know about Softaken Compress PST Software. I downloaded its free trial version and within a few minutes, my file was compressed to a great extent. The special thing is that there was no loss of data, and attachments can also be saved separately. This tool is very useful for those who use Outlook daily and are troubled by large files. The interface is also user-friendly and technical knowledge is not required. If anyone needs, they can download the trial from the official site and see it.

Managing large PST files manually can be extremely risky and time-consuming. The MailsDaddy PST Split Tool offers a safer, more efficient method to handle oversized Outlook data files. This tool supports both ANSI and Unicode PST formats and allows users to divide files based on size, date range, folder selection, or sender’s email ID. It operates smoothly without needing MS Outlook installed, and maintains complete data integrity. Users can confidently process multiple PST files without the risk of corruption or losing crucial emails, contacts, calendars, and other mailbox items. The software is highly compatible with Windows and works flawlessly across Outlook 2003 to 2021. For professionals who work with high-volume Outlook data and need a secure way to declutter, back up, or archive data—this tool offers excellent functionality and peace of mind.

My Outlook PST file had become very large, due to which Outlook was freezing frequently. Then I used the DataVare Outlook PST Compact Expert Tool. With the help of this tool, my PST file was easily compacted, and Outlook started running fast again. The interface of this tool is simple, and anyone can use it easily. The best thing is that the data remains absolutely safe. I would recommend it to everyone who is facing the problem of the PST file.
