We have installed an Exchange 2010 system, side by side with Exchange 2003, and this is our final step. We've successfully run the following 2 scripts (atleast they completed with no errors): Get-EmailAddressPolicy | WHERE { $_.RecipientFilterType -eq 'Legacy' } | foreach { Set-EmailAddressPolicy $_.Name -RecipientFilter (.\ConvertFrom-LdapFilter $_.LdapRecipientFilter) -ForceUpgrade } Get-AddressList | WHERE { $_.RecipientFilterType -eq 'Legacy' } | foreach { Set-AddressList $_.Name -RecipientFilter (.\ConvertFrom-LdapFilter $_.LdapRecipientFilter) -ForceUpgrade } When running the final one (for the GAL) it fails as follows: Command = Get-GlobalAddressList | WHERE { $_.RecipientFilterType -eq 'Legacy' } | foreach { Set-GlobalAddressList $_.Name -RecipientFilter (.\ConvertFrom-LdapFilter $_.LdapRecipientFilter) -ForceUpgrade } Resulting text in EMS: [D] Do not run [R] Run once [S] Suspend [?] Help (default is "D"): R "((Alias -ne $null) -and (((((((((((((((ObjectCategory -like 'person') -and (ObjectClass -eq 'user'))) -and (-not(Datab ase -ne $null)))) -and (-not(ServerLegacyDN -ne $null)))) -or (((((ObjectCategory -like 'person') -and (ObjectClass -eq 'user'))) -and (RecipientType -eq 'UserMailbox'))))) -or (((ObjectCategory -like 'person') -and (ObjectClass -eq 'cont act'))))) -or (ObjectCategory -like 'group'))) -or (ObjectCategory -like 'publicFolder'))))" is not a valid recipient f ilter for the default global address list "Default Global Address List". To upgrade the object's Exchange version, use "-RecipientFilter {((Alias -ne $null) -and (((ObjectClass -eq 'user') -or (ObjectClass -eq 'contact') -or (ObjectClass -eq 'msExchSystemMailbox') -or (ObjectClass -eq 'msExchDynamicDistributionList') -or (ObjectClass -eq 'group') -or (Obj ectClass -eq 'publicFolder'))))}". + CategoryInfo : InvalidOperation: (\Default Global Address List:ADObjectId) [Set-GlobalAddressList], Inv alidOperationException + FullyQualifiedErrorId : 788CD283,Microsoft.Exchange.Management.SystemConfigurationTasks.SetGlobalAddressList [PS] C:\temp> Additionally, when I attempt to open the Default Global Address List in the EMC - it doesn't open, no errors, no prompts, simply nothing. What can I do to upgrade this one? Any ideas or cautions? DQ

Hi, I have never used the script ConvertFrom-LdapFilter. I find it very easy to copy/paste the information from the below Technet Article. Set-GlobalAddressList "Default Global Address List" -RecipientFilter {(Alias -ne $null -and (ObjectClass -eq 'user' -or ObjectClass -eq 'contact' -or ObjectClass -eq 'msExchSystemMailbox' -or ObjectClass -eq 'msExchDynamicDistributionList' -or ObjectClass -eq 'group' -or ObjectClass -eq 'publicFolder'))} Upgrade Default Address Lists from LDAP Filters to OPATH Filters http://technet.microsoft.com/en-us/library/dd335105 Martina Miskovic

Thanks for the quick response. I ran the above and the versions (when running get-globaladdresslist .....exchangeversion) now shows that its updated as it = 8.0.535.0. I still can't click on the default global address list in the EMC (nothing happens). Also, the other address lists I can rclick and have options for : apply, remove, edit, help and on the default global address list the only option is 'help'. Is that OK?DQ

In Exchange 2010 there's nothing that can be done with the GAL in EMC, so yes...That's Ok. Martina Miskovic

Awesome. Thanks again!DQ
