Eddy, this has helped stop a lot of emails coming through to me.
Click on the three dots on the email ...
Go down to VIEW and VIEW MESSAGE SOURCE
You will get a box full of computer speak.
Scroll down a bit until you see the FROM line - mine shows as Message-ID, Thread Topic, Thread-Index, From
It then gives you were the email was sent from.
Highlight the address and copy
Open SETTINGS - the cog thingy at top of page in Outlook.
Select Junk email and ADD it to the Blocked Senders and Domains.
I have been copying in the full email address and saving and then just the domain part aswell, and saving.
So it would be " ******@wdIZPKJqQKBlkEwFDUup.com" , SAVE, and then, " wdIZPKJqQKBlkEwFDUup.com" & SAVE
Touch wood, rabbitts foot and any other lucky charm but Botley Road and the likes appear to have been thwarted for now. Most of the ones I get are one's you can just block from the email itself.
I am still sending every single one to ******@phishing.gov.uk , but not sure what they do, if anything.
Still get some through but seems to have stemmed the tide. They were previosuly coming from the likes of "******@screwfix.com", ie: proper words, but now they are coming thru from random number / letter generated addressess.
It has worked for me for the moment, give it a go and hopefully it'll work for you>
