Throttling The Quantity of Emails Flowing Out of Exchange 2013

Problem:

Client gets blacklisted every time they do a mail merge and send out more than x amount of emails at time.

Solution:

Creating a new throttling policy for a single user:

  1. New-ThrottlingPolicy -Name LimitMessagesSent -RecipientRateLimit 30 -MessageRateLimit 1
    1. LimitMessagesSent – limits the number of recipients that a user can send in 24 hours
    2. MessageRateLimit – the total amount of emails sent out per minute

Creating a new throttling policy for the entire organization:

  1. New-ThrottlingPolicy -Name LimitMessagesSent -RecipientRateLimit 30 -MessageRateLimit 1 -ThrottlingPolicyScope Organization
    1. LimitMessagesSent – limits the number of recipients that a user can send in 24 hours
    2. MessageRateLimit – the total amount of emails sent out per minute

Review throttling policies in place:

  1. Get-ThrottlingPolicy -Identity PolicyName | Format-List

Deleting throttling policy:

  1. GetThrottlingPolicy PolicyName | RemoveThrottlingPolicy
