I am having trouble with my Outlook while trying to compress some old PST files to reduce their size. Every time I start the compression process, Outlook becomes unresponsive and eventually freezes. I have already tried restarting Outlook and my system, but the issue persists. Has anyone else faced this problem before? What could be causing Outlook to freeze during PST compression, and what is the best way to fix or avoid this issue? Any reliable solution or alternative method to safely compress or reduce PST file size would be really helpful.
