Hi,
You may implement the address book segregation by the following ways: The method uses the Custom Attribute set for the iusers
1. Create Address List for Organization 1
New-AddressList -name “Organization 1” -RecipientFilter {(CustomAttribute1 -eq “Org 1 Member”)} -DisplayName “Organization 1 List”
2. Create Global Address List for the Organization 1
New-GlobalAddressList -name “GAL_Organization 1” -RecipientFilter {(CustomAttribute1 -eq “Org 1 Member”)}
3. Create corresponding Offline Address List
New-OfflineAddressBook -name “OAB_Organization1” -AddressLists “GAL_Organization1”
4. Create an Address Book Policy for Org 1
New-AddressBookPolicy -name “ABP_Org1” -AddressLists “Organization 1” -OfflineAddressBook “OAB_Organization1” -GlobalAddressList “GAL_Organization 1”
5. Assign the ABP to the Org 1 Users
Get-Mailbox -resultsize unlimited | where {$_.CustomAttribute1 -eq “Org 1 Member”} | Set-Mailbox -AddressBookPolicy “ABP_Org1”
Mailboxes that have 'Org1 Member' as the value of the CustomAttribute1, will only see Other members of their Organization.
