Below outlined steps will create an Address Book policy in Exchange 2013 to make sure Contoso’s address book is only visible to Contoso employees.

Prereq’s:

When a new user is created the user should be stamped with the right email address.

Process:

CMDLets 3 and 4 will find users daily with the right email id – say contoso.com and add CustomAttribute15 to contoso.com to all discovered user’s and assign the appropriate address book.

Simply use a notepad and replace contoso.com to yourdomain.com and CustomAttribute15 to the number you want.

This is the simplest possible form of achieving this task – for complex requirements please adopt other ways.

1. Create Address Lists, Room Lists, GAL, OAB and ABP

New-AddressList -Name “contoso.com_AL” -RecipientFilter {((RecipientType -eq ‘UserMailbox’) -or (RecipientType -eq “MailUniversalDistributionGroup”) -or (RecipientType -eq “DynamicDistributionGroup”)) -and (CustomAttribute15 -eq “contoso.com”)}

New-AddressList -Name “contoso.com_Rooms” -RecipientFilter {(Alias -ne $null) -and (CustomAttribute15 -eq “contoso.com”)-and (RecipientDisplayType -eq ‘ConferenceRoomMailbox’) -or (RecipientDisplayType -eq ‘SyncedConferenceRoomMailbox’)}

New-GlobalAddressList -Name “contoso.com_GAL” -RecipientFilter {(CustomAttribute15 -eq “contoso.com”)}

New-OfflineAddressBook -Name “contoso.com_OAB” -AddressLists “contoso.com_GAL”

New-AddressBookPolicy -Name “contoso.com_ABP” -AddressLists “contoso.com_AL” -OfflineAddressBook “contoso.com_OAB” -GlobalAddressList “contoso.com_GAL” -RoomList “contoso.com_Rooms”

2. Find all users you want to assign the ABP and set CustomAttribute15 to contoso.com

Get-Mailbox -resultsize unlimited | where {$_.EmailAddresses -match “contoso.com”} | Set-Mailbox -CustomAttribute15 “contoso.com”

3. Apply the ABP on all those users

Get-Mailbox -resultsize unlimited | where {$_.CustomAttribute15 -eq “contoso.com”} | Set-Mailbox -AddressBookPolicy “contoso.com_ABP”

4. Schedule script 2 and 3 to be run daily using task Scheduler
