My email information is under the threat
This great day I've only opened MS Outlook 2016 and I haven't even opened my Inbox. My .pst password looks like was reset. What actually happened, I can’t know, I want to bring all the my data back.
If you think your account has been hacked go to https://login.live.com/login.srf?wa=wsig... type in your email and password, if your password fails and you are sure you are typing in your password correctly, hit forgot password and select I think someone else is using my microsoft account.
If such an error takes place while opening PST files, this might be a corruption case. I'm little sure about the corruption here as the user followed the things asked in the error with no luck. SCANPST.EXE, the Inbox Repair tool for MS Outlook, can play an important role in this situation. It can fix the PST files if they are corrupted. Sometimes it may fail if the files are severely corrupted. In such situation, you may recovery outlook password or in case it can't help you, then visit Google or https://www.outlookrepaironline.com/
