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

    I migrated to Exchange 2013 from 2010 an did not remove the CAS array because I was in a coexisting state with 2010 and 2013 for about a month. My CAS array still exists but has no members. I have 2 servers with MB and CAS roles in a DAG. When 1 of our 3 DB’s fails over to the second server, all clients within the organization (Outlook 2010 and 2013) lose connectivity and remain disconnected for a few hours. It doesn’t matter if the mailbox is in the DB that failed over, all clients are affected. I’ve worked with MS on this issue for just over a month now and they have not resolved. They are aware that my CAS array still exists. I wonder if removing the array will do the trick?

    • Hi Rich,

      if you have no more members in the CAS Array, I would suggest deleting the old CAS Array object with ADSIEdit. If all clients are moved to Exchange 2013 and you don’t have an Exchange 2010 Server anymore there is a good Chance to solve your connectivity issue.

      Cheers,
      Chrish
