My Outlook PST file has grown very large, and it is slowing down the performance of my Outlook application. I am worried that if the file size keeps increasing, it might get corrupted. I have heard about compacting PST files, but I am not sure what the safest method is to do this without losing any data or attachments. Can anyone guide me on how to compact oversized PST files in MS Outlook step by step? Also, are there any reliable tools that can help reduce the file size effectively?
