Hi @Weng, Fanky ,
Once an email is marked as phishing scam, it is automatically moved to the Deleted folder.
I would suggest that you recover the deleted emails that were marked as Phishing scam and move them to your Inbox. Check the link below:
Restore deleted email messages in Outlook.com
Messages from addresses or domains on the safe senders list won't get moved to your Junk Email /Deleted Items folder. Refer to this article to add the email address to safe sender list: Block senders or unblock senders in Outlook
Then ask the senders you accidentally reported as Phishing scam to send you a new email to check if it will go through.
