Outlook 365 Online Phish Alert reporting button
A user can report any email as a phishing email. The reported email will be in the users' Sent Items as a forwarded message and will be deleted from the user's inbox. If the user incorrectly reported the email, they can retrieve it from their Deleted items/Trash.
In O365, the Phish Alert Button (PAB) will appear on the top right of the email message, as shown below. If you do NOT see the PAB, see the note below.
Note: If a user is using Outlook Online and the new Outlook toggle is turned on, the PAB will be found in the drop-down menu of a message.
Open the email message and then click the "3 Dots" icon to open the More Actions pop-up menu as shown below.
Then click the "Phish Alert" item near the bottom of the pop-up menu.
