I am unable to open a PST file because it is asking for a password I do not know. I do not remember setting one. I am using Outlook 2016 on Windows 10, and the PST is about 2.3 GB. When I try to open the file, Outlook immediately prompts for the password and won't let me proceed. I have tried restarting Outlook and running Repair Office, but no luck. Any safe ways to recover or remove the PST password without corrupting my data?
