Exchange 2013 STD block external mail comunications for some users

Hi to all, i'm facing in a problem where i'm need to limitate some user to comunicate with external users. I had created two transport rules, one for inbound and other one for outbound mail flow. ...

Hello Marco,

Can you change the order of the rule conditions to the following:

In the outbound rule the settings are:
-the recipient is outside the organization

-And the sender is "user" or "group"

-action: reject the message and send this error: "you are not able to...."

- Stop Processing More rules

Also, check the following:

Get-RemoteDomain | select IsInternal | fl

Give it a try and let us know.

Thanks,

Mike

  Hi Michael,
  unfortunately, it's doesn't work.
  The result of the command is:
  
  IsInternal: false
  
  Other suggestion?
  
  Thanks in advance.

    You tried updating the rule also? This can take up to 4 hours to apply unless you restart the transport service.
    
    The user can still send e-mail's externally?
