How to Upgrade Address Lists During Exchange 2007 Migration

At the end of an Exchange 2007 transition you should upgrade the Address List and Global Address List objects to Exchange 2007 OPath format.

In organisations with only the default Email Address Policy, Address Lists, and Global Address List, you can complete the Exchange upgrade with a script instead of running each command manually.
Download the Exchange Transition Script.

Upgrade the default Address List objects to Exchange Server 2007 OPath format using Set-AddressList.

[PS] C:\> Set-AddressList "All Users" -IncludedRecipients MailboxUsers

[PS] C:\> Set-AddressList "All Groups" -IncludedRecipients MailGroups

[PS] C:\> Set-AddressList "All Contacts" -IncludedRecipients MailContacts

[PS] C:\> Set-AddressList "Public Folders" -RecipientFilter { RecipientType -eq 'PublicFolder' }

Upgrade the default Global Address List to Exchange Server 2007 OPath format using Set-GlobalAddressList.

[PS] C:\> Set-GlobalAddressList "Default Global Address List" -RecipientFilter {(
Alias -ne $null -and (ObjectClass -eq 'user' -or ObjectClass -eq 'contact' -or O
bjectClass -eq 'msExchSystemMailbox' -or ObjectClass -eq 'msExchDynamicDistribut
ionList' -or ObjectClass -eq 'group' -or ObjectClass -eq 'publicFolder'))}
