Rob Koch, Thank you very much, you have been very kind, and you have provided very useful information.
As you say, the problem is appearing in Outlook, and they are being reported by users in Spain and Latin America. When you sign in to Outlook, a page is displayed in a new tab, where it is indicated that Microsoft
is rewarding with products such as iPhone X, Samsung Galaxy and PlayStation 4 by answering some questions. Subsequently, the page indicates the product obtained, and the user is asked to enter
the bank details to charge a small fee.
I have contacted abuseAToutlookDOTcom to see if they can help me.
I understand that as you comment, Rodrigo and his team may not be able to help me.
I don't know if the ads that appear in MSN and Outlook are shared on both platforms, although I guess this will depend on the creator of the campaign.
Thank you very much and I will keep you informed.
