I am facing an issue with my Outlook PST file. It has become very large and is slowing down Outlook performance. When I tried to compress the PST file, it did not reduce in size properly, and sometimes showed errors during the process. Can anyone guide me on how to safely compress a problematic PST file without risking data loss? Also, are there any reliable methods or tools that can handle this situation better than the default Outlook compression feature? Looking forward to your suggestions and solutions.
