As you can see below, we use a banner and “[EXT]” in the subject.  This works well as an anchor for education (I have 
the numbers to prove it).  In addition, you may want to explore additional text if the email is coming from an external 
source and includes those keywords (HR, payroll, direct deposit, bank account) or names of executives.  If anyone needs 
details on how we do this with O365, feel free to reach out.

Thanks,

Josh

**External Email**
Hi -,

One thing we are looking at is prepending all external emails’ subject with “[External]: “. While this would not block 
the email, it would become a red flag if an email is spoofing the identify of an internal account.

My understanding is that you can setup a rule on a specific Inbound Connector in Exchange and add a rule to check 
whether the Sender is authenticated or not.

Subject: [SECURITY] How do you block spoofed communications from HR, Payroll, the President...?

Hello Colleagues, I am wondering what other universities are doing to block emails to users that have spoofed official 
people or offices on campus. Emails claiming to be from HR or Payroll, or the President.  Do you have a way to 
'guarantee' official communications so that end users can easily distinguish between the real and the fake?
We have an Office 365 email environment and also have many third party organizations that send mail, for our, as our, 
domain.
Any all thoughts are welcome

Thank you for your time
