Hi Pubudu
Do you have some more information on this?
We have set up a Compliance rule as follows using the Full headers to search for the group ID (I confirmed this match using Email Log Search for the inbound email to the user we are trying to prevent getting the email):
Locally applied
1. Email messages to affect
Internal - Sending
Internal - Receiving
2. Add expressions that describe the content you want to search for in each message
If ALL of the following match the message
3. If the above expressions match, do the following
Quarantine the message
A. Address lists
Use address lists to bypass or control application of this setting
Only apply this setting for specific addresses / domains
[List contains the recipient email address]
B. Account types to affect
C. Envelope filter
Nothing selected
However the email still seems to arrive in the users inbox.
Any advice would be great!
