I am using Outlook on Windows 11, and my PST file has become quite large over time. I have already deleted a lot of old emails and attachments, but the file size has not reduced much. I heard that compacting the PST file can help reclaim space. Can anyone please guide me on how to compact an Outlook PST file in Windows 11? Also, are there any precautions or steps I should take before starting the compacting process to avoid data loss or Outlook freezing issues?
