Managed Folder Policies and Managed Folder Assistant

Hi Experts

A little bit confused on the relationship between these two in Exchange 2007 SP1.

I understand that I can apply a MFP to a mailbox as per

I can also schedule the MFA as per

However, two questions:

i) The first article - just applying the MFP to a mailbox - does this mean the policy actually runs on the mailbox? Or does it not run until the MFA is scheduled for it to run?

ii) If applying a MFP (but no MFA) to all mailboxes on my server, I assume this will take a lot of processing power - what if it got to much and I wanted to cancel it, how could I do that?

iii) Likewise, if the MFA was running and it was taking too much resources, how could I cancel?

Thanks in advance.

I think the critical distinction which needs to be made here is between a Managed Folder Mailbox Policy and the Managed Folder Assistant.

The policies define the retention settings you wish to apply to mailboxes, the managed custom folders you want to create and so on. It is the managed folder assistant's task to implement the settings in these policies. If the assistant doesn't run, the settings are not applied.


1) The policy is only applied when the assistant runs. Processing managed folder policies is a resource intensive process, so it is only performed when you schedule it do so (ideally, you would schedule it over night or when there is low load on the server).

2) It's not going to take any processing power if the assistant is switched off. The retention settings will never be applied.

3) If the assistant is running and you decide to stop it, use the Stop-ManagedFolderAssistant cmdlet at the Exchange Management Shell. You can specify a server to stop the assistant on using the -Identity parameter.

Hello Matt

Got it!

To confirm - applying the Managed Folder Mailbox Policy to a mailbox DEFINES the settings that will be applied, but doesn't actually apply them to the mailbox. Only when the Managed Folder Assistance is scheduled to run for the first time will changes to the mailbox (e.g items removed from Inbox > 100 days) take place?

Just applying an MFP alone will not change the mailbox in any way.


Yep, that's exactly correct.
