Hi Winnie,
Good day! Thanks for your email and valuable help.
1, Your email with all details steps and hyperlink are very useful.
2, I followed the steps for "Secure your Microsoft account (if you still have access)" and "Stop the blackmail/phishing emails safely".
Specially after signing out for 24 hours, my outlook account stops receiving black mails. New arriving emails are keeping normal
3, However, all rewritten emails are only part of them recovered. Still big half remains rewritten. I will give it another day to see whether all of them get restored.
4, My emails under inbox still missing- I cannot find them.
Kind regards
Monica
