Because of this, Outlook has started running slowly, and sometimes it even shows errors while sending or receiving emails. I have limited storage space on my system, and creating a new PST file every time is not a convenient option for me. I want to reduce the PST file size without losing important emails or data. Can anyone please suggest the best and safest ways to reduce a large PST file size in Microsoft Outlook? I am looking for manual methods as well as reliable tool-based solutions, if available.

Over time, this file can become very large, causing Outlook to slow down or even freeze. In such cases, reducing the size of the PST file becomes necessary. If your Outlook is running slowly or your PST file has become too large, Softaken Compress PST Software can help. This tool compresses the PST file without any data loss & improves Outlook’s performance. It works with all Windows & Outlook versions & is very easy to use.
