Exchange 2013 - remove default address policy

Hi
We are setting up Exchange 2013 as a multi-tenant and followed various documents and this works a treat with 1 exception - the default address policy is also applied.

We have address book policies for companya, companyb etc..  so the emails are bob@companya etc...
but the top level domain is: toplevel.co.uk

When it creates the account, it finds the correct address book policy and applies but it also applies the default one .. so the user is bob@companya AND bob@toplevel.co.uk

We want to still have the default ones as we have users in toplevel.co.uk  ... but tenants do not need this address

Hi

So we have 4 address policies (and a default one)

When I create a user via powershell we say we want to use Address Policy 2  .. and it does it  (which adds @policy2.co.uk) to the users account

BUT it also adds what is in the default policy

So when we create the user in powershell and put -AddressBookPolicy 'Policy2' we only want the user to have this policy and not the default one

"The first email address policy that identifies a recipient configures the recipient's email addresses. All other policies are ignored, even if the first policy is unapplied and can't configure the recipient's email addresses."

You mean to say this isn't happening?

Thats correct ... in our policy list it shows

Policy1 - Priority 1
Policy2 - Priority 2
Default Policy - Lowest

When we select use policy2 .. the email poilcy is applied but then it also applies the default

Are you using any conditional filtering based on OUs or attributes?

Yes - both for the policy .. so for policy2 it must be in a certain ou and attribute set .. which is working as policy2 is being applied

You need to somehow set the value for the RecipientFilterApplied to false.  Unfortunately, in my experience, it cannot be done through PowerShell ... :,( .  But if you run through the EMC to "update" that policy you can chose the schedule to apply the policy to "Do not apply".

Alternately, you can set the value for msExchRecipientFilterFlags to 0 for the "Default Policy" through ADSIEdit.

Here is the ADSI Edit path if you need it ... CN=Default Policy,CN=Recipient Policies,CN="YourOrganizationName",CN=Microsoft Exchange,CN=Services,CN=Configuration,DC="Contoso",DC="com"

It won't remove the addresses already set but it should prevent that specific policy from being applied to new users as they are created.
