Hi Frnds, I have Configured my Exchange in Hosted Environment. In My Setup i have Configured Exchange CCR Cluster First named E2K7MBX01 and my OS Cluster name is E2K7MBX. after Installing Exchange on Both Active and Passive Node i have First Removed the MailBox Role From Passive node and after removing the Mailbox Role From Passive node i have Destroyed the Cluster and the removed the Mailboxrole From Other node. After Removing the Mailbox role from both node i have ConFigured the New Cluster Named E2K7MBX01 as os Cluster and after that i have install exchange CCR cluster on my node-1 and node-2 named E2K7MBX and it working fine. Now the Problem is that when i am starting the Exchange Management Console (EMC) The Old Mailbox Cluster Show there with it's Mailboxes (E2K7MBX01). I want to Delete this Old CCR Cluster name From EMC. is it Possible if Yes then what is the prosidure to remove it. please give me the help to solve this issue

Hi, Check the schema configuration part with ADSIEDIT. Probably there is still an object that points to the old mailbox cluster. Greetzz, Timmy

Hi, You can try to remove it from AD if its not removed, try this : Remove the Exchange 2007 server from Active Directory. I ended up deleting the entire “Microsoft Exchange” branch from ADSIEdit (Configuration Container > Services > Microsoft Exchange) as my Org only counts one server.You have to preform the same on DC Ripu Daman Mina | MCSE 2003 & MCSA Messaging

Hi SPeeDyt.. Thanks For The Quick Reply... I have trid to Find An Old Object of MailBox Cluster in ADSIEDIT but i couldnt found any old cluster mailbox object in ADSIEDIT. is there any other way to remove it From EMC.

EMC gets all the information from the schema... Maybe you should check the replication of the dc's? Did you check the schema on the dc that is the logon server of the machine where you run EMC? Greetzz, Timmy

SPeeDyT I have Installed the MailBox Cluster on Separate server not on the DC and yes i have checked schema on DC but i cant found old MailBox Cluster Instance. please Sugest me a path where i have to check for that object.

Hi, Should be something like this: CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=Exchange,CN=Microsoft Exchange,CN=Services,CN=Configuration Start from right to left :-) Greetzz, Timmy

Hi SPeeDyT... I have Found the OLD MailBox Cluster Object in CN=Configuration>CN=Services>CN=Microsoft Exchange>CN=First Organisation>Administrative Groups>CN=Exchange Administrative Group>CN=Servers. Now what i have to do please guide me.

Hi, Just delete it. Since you don't use it anymore you normaly can just delete it. But verify it first.. are there more than one object in that container? greetzz, Timmy

i have Found both object Current MailBox Cluster Object ( E2K7MBX ) and Old MailBox Cluster Object ( E2K7MBX01 ) in In current Object ( E2K7MBX ) there are 3 Sub Object 1) Information Store 2) Microsoft System Attandance 3) Protocol. But in Old Oject there are Four Object 1) Information Store 2) Microsoft System Attandance 3) Protocol and 4) Microsoft MTA. Now what i have to do. should i delete this old Oject ?

I presume there is nothing more attached to that old object (E2K7MBX01). Than you can just delete it. If you are not sure about deleting... move it somewhere out of the servers container. Greetzz, Timmy

Hi SPeeDyT I also have Adsitional DC in my Environment so i have to delete it From Both Location DC and ADC ???

No you don't have to delete it on both locations. The other dc will get the changes by replication.. Greetzz, Timmy

Thanks SPeeDyT I have Deleted that Object and My Problem is solved after Deleting it. Thanks For the Quick Help and Support. Mahipal

Hi SPeeDyT.. After Removing the old Object My Cluster is not able to start Exchange Information Store Instance Service in my my cluster. plaese help me in this issue.
