Alert when user sends lots of emails in short time. RRS feed

  • Question

  • Hi guys, I'm new to Exchange 2016 and wanted to if there is a way to configure alerts, to notify admins when a user sends a lot of emails in a short period of time (minutes).

    I know it does not make a lot of sense, but still I want to know if there is a way or not.

    If it helps, we also use SCOM 2012 (Maybe it could be achievable by combining the 2 solutions).

    Thanks!

  • Hi,

    As per my experience, from Exchange side, we could use the throttling policy to specifies the number of messages per minute that can be submitted, then assign it to a user.

    New-ThrottlingPolicy -Name LimitMessagesSent  -MessageRateLimit "<number>"
    Set-Mailbox -Identity "<mailboxname>" -ThrottlingPolicy LimitMessagesSent

    Then we may find a way to generate an alert from SCOM if the message number exceed the specified limit.

    Hope it helps.

    Regards,

  • Manu, the request was for an alert, not a restriction. Agustin, please let us know if this is not the case.

    In any event, Exchange does not have any built-in ability to send alerts based on your scenario. Instead, you'd want to run a powershell script on a schedule that counts up messages and sends an email when a threshold is reached.

    Office 365 can do this with Cloud App Security BTW. That product has some on-premises reach as well, but I've not tried it with this scenario.
