How to remove the unverified sender message?

Anonymous

Hi,

I keep getting an 'unverified sender' message in Outlook (desktop and web app). I've added the address to 'trusted sender' and I've whitelisted the domain but still keep getting it.

The sender is 'trusted' and a reputable domain.

Is there anything else I can do on my side or is it down to the sender?

Many thanks,

Charlie

URL rewrites to force scanning on any device a end user is using to access company data seems to be a surefire way to get this warning from Microsoft, even though its a Microsoft certified email protection API. You may see a link with, for example "https://us-east-2.protection.sophos.com..."When you click it the safe scan happens then your redirected to the original URL.
