MessageRateLimit

    Question

  • I am trying to limit the amount of message a user can email from our Exchange server (2010 SP2 RU6) per minute. From what I understand the MessageRateLimit is exactly what I need.

    I have two throttling policies. The default and a "COM Test" one. I have verified the the "COM Test" is assigned to the mailbox I am testing this with by running Get-Mailbox user@domain.com | fl Thr*

    It shows up at "COM Test".

    I have it limited to 5 for testing. After configuring this I did wait over 30 minutes (read 15 minute is the interval for changes).

    On my Outlook I opened 8 messages and configured them to send to different external email addresses. Once I finished I clicked Send on all of them back to back. So essential I submitted 8 messages within 10-15 seconds.

    They all are going through and I'm getting no NDR like I should be.

    Am I mistaken on the way this should work or is there something overriding what I have set? From what I can tell I have it configured properly and it should be working. My Outlook client is 2013 and I have tested with my iPhone 5 as well but it doesn't work like it is supposed to since all messsages go through.

  • Hi,

    Don't you configure message rate limit on recieve connector ?

    Set-ReceiveConnector:

    Would you get the throttling policy and post here ?

  • I did not configure message rate limit on the receive connector. I was thinking I could just do it on the throttling policy. 

    I'm trying to throttle outbound messages only and not inbound ATM

    I'll have to post the policy tomorrow morning
