I changed my profile display picture in outlook several times and it's reflecting correctly when I check my Outlook profile and account but whenever I send an email, the recipient sees an unknown display picture that I've never set as DP. I don't even recognize the picture it displays to the recipient. There are no accounts such as Facebook or LinkedIn or any other linked to this account. This picture is not used on any account I have anywhere and is not even on my computer or mobile. I've tried to send an email to different recipients just to check and the unknown display picture shows up to all the recipients. I want to get it removed, please help.
Photo A = Correct and recent display Picture
Photo B = Incorrect and unknown display picture shown to recipients of the email.
