Block DisplayName rule
I would like to setup an org-wide Exchange Rule on a 365 tenant that prepend's the email.
- inbound-from-external domain
- where the DisplayName = "John Doe"
I've tried several iterations but can't get it to work. For example, this doesn't work:
Rule description
Apply this rule if
Is received from 'Outside the organization'
and sender's specified properties match these text patterns: 'DisplayName:John Doe'
Do the following
Prepend the subject with 'CAUTION CAUTION'
Finally got it working. See below.
I appreciate the input.
- Wow, great!
- If you need it only for your own mailbox, have a look at this freeware:

You have to modify the flow according your needs.- Thanks for the suggestion, but I need it organization-wide on a 365 tenant.
- Then try to use "A message header includes" instead of "sender's specified properties match these text patterns" - see https://learn.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/conditions-and-exceptions
