Hi Folks,

sometimes you forget to delete the Exchange 2010 CAS Array Object with “Remove-ClientAccessArray” within the Exchange 2010 Shell while migrating to Exchange 2013.

After Deinstallation of Exchange 2010 the “Remove-ClientAccessArray” isn’t available in the Exchange 2013 Shell.

To remove the CAS Array Object open ADSI-Edit and go to configuration

Navigate to this path:

CN=Configuration,DC=DOMAIN,DC=LOCAL
CN=Services
CN=Microsoft Exchange
CN=EXCHANGE_ORG
CN=Administrative Groups
CN=Exchange Administrative Group (FYDIBOHF23SPDLT)
CN=Array
DELETE CAS Array Entry and wait for AD Replication

cas-array

Cheers, Chris

Often I’m confronted with problems of mail submissions in freshly migrated Exchange environments.

In migrated environments it could happen, that the old ExchangeLegacyDN is missing and users can’t answer on old mails. This might happen, when you migrate users between Exchange organizations.

To mitigate this issue, you can add the old ExchangeLegacyDN as X500 proxy address. This fixes the issue and the user’s mailbox is addressable via the old LegacyDN.

You can do this by hand, by ADModify.NET or simple use PowerShell to fix this.

Get-Mailbox -recipienttype ‘usermailbox’ | foreach {$_emailaddress += [microsoft.exchange.data.custom.proxyaddress](“X500:/O=ORG/OU=US/CN=$_.ALIAS”)$_set-mailbox}

Thanks to Frank for this helpful PowerShell cmdlet.

Cheers,

Chris
