7.5.1.Exchange performance settings – turning off the Exchange throttling policies
Throttling is a mechanism of Exchange Server to distribute the Exchange resources evenly between the users. It gives every user the chance to access their emails. The users are limited for example to send max 5 emails in a minute. If this limit is reached, the user is throttled, forcing the user to wait a minute until a new mail can be sent.
The archiving user requires more resources: it needs to access multiple mailboxes, process multiple messages. The standard throttling policy is not suitable for the archiving user (superuser).
If you are experiencing problems that may be caused by these policies, you can turn them off. The commands below are turning off any limitations for the archiving user, allowing to use as many Exchange resources as needed.
Exchange 2013
New-ThrottlingPolicy -Name CAPolicy -ThrottlingPolicyScope Organization

Exchange 2010
New-ThrottlingPolicy -Name CAPolicy

There are 3 commands which must be run in PowerShell to apply the throttling for the superuser:
#1 New-ThrottlingPolicy
Creates a new policy, gives a name to the policy. It is created with default values.
#2 Set-ThrottlingPolicy
This changes the parameters of the policy – turning off any throttling for the contentACCESS user.
This list should be discussed with the customer, they might not allow all these options. This is a matter of support.
#3 Set-Mailbox
Assign the policy to the user.
The whole association can be verified by running this command: Get-Mailbox “Administrator” | fl ThrottlingPolicy
