Almost a year later, but I'm having the same problem. This makes it a lot harder to filter out phishing emails. Any help would be greatly appreciated!

Hi, thank you for the information. I don't see any direct form I can fill with all the information I gathered, so I will follow the recommendation of the third link and simply report the emails from Outlook, as usual. Hopefully they will fix this in the next 10 years when a lot of people has been scammed.

Fast forward to December 2022. The issue still exists and now the spammers/scammers/phishers who are sending hidden sender email address emails have also disabled the sweep function of their emails. Sweep function is available on legitimate emails, not the new wave of hidden sender email address scam emails.

Good luck trying to find a solution. I got in touch with Microsoft using 3 different chats/contact forms and nobody was able to help me. The only solution provided by those agents were to refer me to a different Microsoft team using a new and different form. I wasted a lot of time explaining this problem every time I contacted Microsoft. Apparently, they don't know who can fix this bug or they don't care about it.Anyway, if you eventually find a solution, please let me know, I am still worried about this problem.

Can't see sender email address (Outlook web)

Hi,

I've noticed recently that I am not able to see the sender email address for some emails. Why? How can I fix this?

Example:

If I place the mouse on the sender I see my own email address:

I don't have this problem with most of my emails:

When I check the source of the TV Licensing email what I see is:

Date: Thu, 14 May 2020 03:05:34 -0700

Subject: Your TV Licence expires today

Message-ID:

<DB8PR02MB58514A4F8FBCF5689D1322CFDCBC0@DB8PR02MB5851.eurprd02.prod.outlook.com>

From: TV Licensing <myemailaddress@hotmail.es> , <sirajul_islam1987@hotmail.co.uk>

To: mailto:myemailaddress@hotmail.es

Does anyone know what is going on?

Thank you.

  Hi Thank you for your feedback and a lot of work it really helps. There is what is more and more scammers - of course you marked the sender as an attempt to extort because only so it is that you block it and Microsoft has such an email sender in the list = spammer , or is blocked for all Office 365 so it works = but not aware is very much yours

    Hi, in this case marking the email as phishing and report ir to Microsoft doesn't help. If I do it, Microsoft may block the sender email address, but the real problem would still be there. The scammers only need a new email address to continue their work, while people will still see their own email address or a legitimate email address as the sender email address. This is the real problem here.
    
    Moreover, in the case of the TV Licensing email, the "From" field has two email address, the scammer's one and my own email address. What would happen if I report that email to Microsoft? Would they block my email address?
    
    By the way, since I updated this case the 9th of April, I have receive two new emails using taking advantage of the same bug.
