Removing Exchange 2003 form a DC
Hi Folks,
Here's my situation and I am hoping you can help.
DC1
Windows Server 2003
Exchange 2003
DNS
DC2
Windows Server 2003
DC3
Windows Server 2008 R2
DNS
Due to aging equipment, I need to remove Exchange 2003 from DC1 and demote it to a member server The machine will then be decomissioned. The Exchange data has been exported from DC1 and imported into Office365, and the Exchange services
are not currently running. The FSMO roles have been moved off from DC1 to DC3. All clients and server now use DC3 for DNS.
I have heard of all sorts of horror stories related to removing Exchange from a DC. Based on my situation, can anyone tell me what I need to do to remove Exchange 2003 so that I can demote this DC. The Exchange store has been shutdown for sometime know,
but I need to get this machine off our network.
Any help would be appreciated. I apologize if this is posted in the wrong forum.
Thanks
Hi,
It is not supported to demote a DC running Exchange Server, so I recommend you follow the steps below to uninstall the Exchange 2003 at first.
1. Log on to the server from which you want to uninstall Exchange 2003.
2. Open Control Panel, and then click Add or Remove Programs.
3. In Add or Remove Programs, select Microsoft Exchange, and then click Change/Remove.
4. On the Welcome to the Microsoft Exchange Installation Wizard page, click Next.
5. On the Component Selection page, in the Action column, use the drop-down arrows to select Remove, and then click Next.
6. On the Installation Summary page, verify that the Action column is set to Remove, and then click Next.
7. On the Completing the Microsoft Exchange Installation Wizard page, click Finish.
When you uninstall the Exchange 2003 server successfully, you can demote the DC1 to a member server.
Hope it helps.

I have two exchange2003 one w2k3frontend and w2k3exch
for w2k3frontend from add/Remove program is not working I did it with ADSIEdit
but for w2k3exch I get this message:
This server is the master routing routing group first routing group that contains other serveurs.Impossible uninstalling this server without first select a new master routing for this routing group or delete all servers in that group routing .
This server is the server update recipients for the domain. you can uninstall only after selecting another server update of recipients for this area.
so if this still master routing and the server update recipients for the domain so no problem if I delete from ADSIEdit .
can you please help me

eZikorai,
From what you are telling us, you won't be able to remove Exchange from that system using the setup program - go ahead and remove it manually, both from the server (if necessary) and from the directory (which will definitely be necessary) using the links
we have provided. Here are some good ones:
Removing Exchange 2003 from the Server:
This one is only necessary if you need to remove Exchange but still have the server operational for other purposes - for instance, if it is also a domain controller - http://blogs.msmvps.com/bradley/2011/01/28/manually-removing-exchange-2003-from-the-migration-process/
If the server isn't required for any other purposes, rebuild the operating system on it
Removing Exchange 2003 from the Directory:
Go to the "Remove the Exchange Server 2003 server from Active Directory" section of this link for how to remove Exchange 2003 from the directory:
http://support2.microsoft.com/kb/833396/en-us
One note from Ed Crowley, Exchange MVP - "Do not remove the Exchagne 2003 administrative groups unless you want free-busy problems, leave them there forever."
This should leave you with a system that has no Exchange 2003 and Exchange 2010 is running smoothly with no issues. -
We are trying to upgrade our 2010 Exchange to 2013 Exchange but install tells us that 2003 Exchange cannot be on our domain. We used to have 3003 Exchange but someone uninstalled it but parts of uninstall failed. How can I remove the recognition
of 2003 Exchange in our 2010 Exchange manager? It shows 1 Exchange 2003 server but we want to remove that server from our domain. Thanks.Hi,
Yeah, removing an Exchange server is never an easy job. According to your description, only some partitions of your Exchange 2003 server aren't removed. In this case, I recommend you remove your Exchange 2003 server through ADSIEdit:
Navigate to this path:CN=Configuration,DC=DOMAIN,DC=LOCAL>CN=Services>CN=Microsoft Exchange
>CN=EXCHANGE_ORG>CN=Administrative Groups>CN=First Administrative Group
Right-click and hit delete your Exchange 2003 server in the container CN=server.

Removing Exchange 2003 Public Folders
I am in the process of removing public folders from the old 2003 environment after upgrading to Exchange 2010. The Exchange 2010 is set as a replica and everything seems to have transferred over. What are my steps from here? I have 5 Exchange
2003 boxes to remove. I have read a few guides and believe my last step is to use the script "MoveAllReplicas"? Is there anything special I have to do to remove the last 2003 PF database? Is there a "master copy" which
needs ported to 2010?
Thank you.Hi Ian,
As a last step, after you confirmed that all the PF have been replicated to the Exchange 2010, you can move all replicas from Exchange 2003 to Exchange 2010. The "move all replicas" will actually remove the Exchange
2003 replicas.
Move the public folder replicas to another server:
To move all Exchange 2003 replicas to Exchange 2010, which will actually remove the Exchange 2003 replicas:
From the Exchange 2010 server:
.\MoveAllReplicas.ps1 -Server "Exchange 2003 Server" -NewServer "Exchange 2010 Server"
http://blogs.technet.com/b/agobbi/archive/2010/08/04/how-to-move-public-folder-from-exchange-2003-to-exchagne-2010.aspx
http://exchangeserverpro.com/migrate-public-folders-from-exchange-2003-to-exchange-server-2010/
When the public folder instances displays an empty list the operation has completed.
Associate mailbox databases with another public folder database
If any mailbox databases are associated with the public folder database that is to be removed, you must configure another public folder database as their default public folder database.
1. Identify all mailbox databases that use the public folder database that you want to remove as their default public folder database.
2. Use Exchange Management Console to select another public folder database as the default public folder database for the mailbox databases that you identified in Step 1.
3. Repeat Step 2 for all mailbox databases identified in Step 1.
Once moved you can, dismount the PF databases on Ex2003 and verify all are working from 2010.
Remove the PF database and delete the database files manually
1. Now you are ready to remove your Public folder database. To remove a public folder database click on your Public folder database and under Actions select "Remove":
2. You get a prompt to confirm your Action.
3. A warning appears, indicating that the database was removed and reminding you to manually remove the database file.
4. Browse to the folder specified in the Warning message and delete the .edb file from the folder.

Removing exchange 2003 organization from 2003 Domain
Hello,
My company has fully migrated to Office365 (NOT Hybrid environment) from a local environment consisting of a single domain with a single exchange 2003 server.
Now I will be upgrading the domain to 2012, but I plan on removing the 2003 exchange organization first, before I upgrade domain to 2012.
Would this be the best approach? Will this remove any needed the exchange attributes?
Thank youHi Robert,
After the migration is complete and you can retire your Exchange 2003, there are no any exchange attributes will be affected.
You can refer to the above link to remove the Exchange 2003 server from your organization.

Removing old exchange 2003 routing groups from Exchange 2010.
I have migrated over to Exchange 2010(server2008) from Exchange 2003(SBS2003). I've also already run the uninstall for exchange 2003 on the old SBS 2003 server. The old server itself is still running but exchange has been removed and once I get this fixed
I plan to fully remove the old SBS server.
I now get event ID 5020 and 5006 throughout the day on the new server. From what I've read, this happens because the old routing group connectors still exist.
If I run Get-ExchangeServer I get

Am I correct in assuming that the way to fix this now is to go into ADSI edit and delete records under CN=First Administrative Groups? As in delete CN=Routing Groups and CN=Servers and everything under both of those? I'd try this myself but I'm not aware
of any way to restore those records easily if I'm wrong.
Event ID 5006

As for the servers group. It has the old server under it as shown in the image I posted above. That's actually what stops me from just deleting it because other guides have said not to delete it if an old server
is listed.
Is the SBS2003 server listed because I haven't ran DCPROMO to remove it from the network yet? I am planning to do this but was waiting till I cleaned up all the errors before transferring the 5 FMSO roles and running DCPROMO on the old server.
DCPROMO isn't related to this, no.
So you removed Exchange already? How? With setup? It should have removed the Exchange Server object then.
It is supported to remove Exchange 2003 manually if required with adsiedit:

Error 0xc1037986 during Exchange 2003 std remove
This morning I tried to remove Exchange 2003 on a server due to be decommissioned. During the removal I received a prompt for the installation media, and after I pointed it to my Exchange disk I received this error: "Setup failed while installing sub-component of Windows Active Directory schema update with error code 0xc1037986". It then asked to reboot, so I said yes. After a reboot, none of the Exchange services will start. I've noticed these in the event log:
Exchange Server component Microsoft Exchange Messaging and Collaboration Services failed.
Error: 0x8000ffff - An unexpected error occurred.
Exchange Server component Microsoft Exchange Forest Preparation failed.
Error: 0xc1037986 - Cannot find the file.

I thought I would reapply SP2 and try the removal again, but SP2 will not install because I can't start the Exchange services.
The error I am receiving matches up with "Microsoft Exchange Forest Preparation failed". Why would it be trying to run forestprep? Is there a course of action for this server now - it's in a very bad way!I know this is an old thread, But I ran into this issue and discovered that the sbs 2003 r2 disks that were used for install wouldn't work for exchange2003 removal. since sbs2003 is nolonger available on technet, I downloaded and extracted the exchange 2003
iso ( no service packs). when asked for the sbs disk i pointed the wizard to D:\exchange2003disk\SETUP\I386\EXCHANGE and the wizard completed without error.
I hope this helps save someone the time it took me to dig through old boxes of disks looking for sbs2003 disks that would work
This did the trick for me also. I was using Exch2003SP2 media when I received the "Setup failed while installing sub-component of Windows Active Directory schema update with error code 0xc1037986" error, but when I re-attempted the uninstall using
Exch2003 (w/o any Service Packs) the uninstall completed successfully and prompted for a reboot. The Microsoft Error Reporting service popped up with 3 error reports that were generated during the uninstall and requested permission to send the reports
(which I did not) and I just rebooted instead as instructed. After reboot, system displayed message that some services could not be started. Checked the services and found that "Microsoft Exchange Management" and Simple Mail Transfer Protocol (SMTP)"
services were still listed and set to Automatic. Changed startup to Manual on each, rebooted again w/o incident. So the removal of Exch2003 with original media works, but is not 100% clean (no surprise there) during the uninstall cleanup. This is the
1st of 2 old Exch 2003 servers I am retiring. I suspect the 2nd one will behave similarly when we're ready to shut-down that unit also. Thanks for the pointers. -
Demoting and Removing Exchange 2007 Server
Oh, I mistakenly saw 2003, and I thought you were removing Exchange 2003. My bad.
Run the uninstaller on the old system. It will take care of the rest. It will probably error out and give you reasons, clean up the reasons and run the uninstaller again. Once it's uninstalled properly, then you can power off the server and everything should be good. Don't forget your send connectors. I forgot that in my travels once.At one of our locations we recently migrated all exchange mailboxes to a new Exchange 2007 on new OS platform, moving away from Server 2003. Everything to my knowledge has been migrated, users should be all connecting to new server, all connector headends have been updated, etc. As a test, I shutdown the old Exchange server (without uninstalling) but we ran into issues that day with Outlook constantly (every 5-10 minutes) asking for the user's password, slow loading of folder data, etc.; reboots/application restarts did not resolve. We turned the old Exchange server back on and all is now well. My theory is this is due to the schema still containing info about the old Exchange server. If I uninstall Exchange completely, thus removing it form schema, could I expect to have this issue resolved? Obviously I only get one chance on this, so...

Legacy integration between Exchange 2003 and Exchange 2010
Dear Team,
we are using Microsoft Exchange 2003 & 2010 Server for Emails, now we have both servers are connected, we want to raise new Single incident request for doing this activity, we want disconnect 2003 server from 2010 server so accordingly need support,
we are ready to pay for this incident,
pls do the needful,
Thanks & regards
Anteshwar BhosaleHi Anteshwar,
If you want to remove Exchange 2003 from your coexistence environment, please perform the following procedure:
1. Move all mailboxes to an Exchange 2010 server in the organization.
2. Move all content from the public folder database on the legacy Exchange 2003 server to a public folder database on an Exchange 2010 server in the organization.
3. On Exchange 2003 servers, for each offline address book (OAB), move the generation process to an Exchange 2010 server.
4. Verify that Internet mail flow is configured to route through your Exchange 2010 transport servers.
5. Verify that all inbound protocol services (Microsoft Exchange ActiveSync, Microsoft Office Outlook Web App, Outlook Anywhere, POP3, IMAP4, Autodiscover service, and any other Exchange Web service) are configured for Exchange 2010.
If all above steps have been prepared, we can remove the last Exchange 2003 server from the Exchange 2010 organization from ADSIEdit. For detailed steps about this, please refer to:

Migration of domain 2003 and exchange 2003
dear sir,
presently we have domain controller win2003 std sp2 and exchange server 2003 sp2 ,installed on domain controller
we need to migrate from exchange 2003 to exchange 2010 and then to exchange 2013. please suggest the procedure step by step
can i migrate exchange 2003 to exchange 2010 with win2012 R2 std in domain 2003
or we need to first upgrade domain controller or exchange server.Hi,
First, we should note that only Exchange 2013 SP1 is supported on Window 2012 R2. And it is not recommended to install Exchange server on DC server.
Since both Exchange 2010 and Exchange 2013 can run at least Exchange 2003 domain/forest functional level, we can upgrade Exchange first and then raise the functional level.
Because Exchange 2013 can't coexist with Exchange 2003, you need to remove Exchange 2003 server before you decide to upgrade to Exchange 2013.
Hope this helps.
Best regards,
Belinda

Exchange 2003 to Exchange 2010 Public Folders
Hi Gurus, I’m in the process of moving public folders from Exch03 to Exch2010 and I have some clarifications before I proceed with this task. As I have understood the replication process between public folders working in a multi-master environment, I still
need some deep understanding. Okay, the task is to ensure that we don’t lose any PF when I remove the last Exch03 where there’s a lot of PF residing. From my understanding, these PFs found at Exch03 are only replicas from Exch2010. From testing I can verify
that the Outlook clients are looking at Exch2010. The way I tested this is by creating a test PF from Outlook and it did reflected on Exch2010 PF. Looking Exch03 for a couple of days, the test PF never reflected there so I'm just just assuming that there's
no replication happening between Exch2010 and Exch2010.
Please verify on this. Does it mean that Exch2010 is not replicating to Exch03?
If yes, if I remove the PFs from Exch2003 without moving the replicas first to Exch2010, like plainly removing them for decommission, will that delete/remove the PFs on Exch2010?
I have a feeling that it don’t because the PFs I’m creating/deleting at Exch03 are all replicas and I don't see any of the PFs that I deleted at Exch03 to also get deleted at Exch2010. More likely the PFs I'm creating at Exch2010 are not replication across
to Exch03 and therefore removing these PFs at Exch03 should not affect the PFs at Exch2010.
Please confirm on this before I proceed.
Note that I've already taken copy of these Exchange servers because these are all VMs.
Thanks....Hi,
When you add Exchange 2010 to the replica list on Exchange 2003 server, it will replicate the Exchange 2003 Public Folder hierarchy and content to Exchange 2010, not from Exchange 2010 to Exchange 2003.
You can remove public folders on Exchange 2003 without affecting the public folders which have been replicated to Exchange 2010.
Before you decide to remove Exchange 2003 server, I recommend you put the Exchange 2003 server offline temporarily to check if Exchange 2010 works well.
Best regards,
Belinda

Exchange 2010 System Public Folders trying to replicate to decommissioned Exchange 2003
I was checking the mail queue on Exchange 2010 and noticed several hundred messages in retry. Looking at the messages I found that they were all destined for an old 2003 exchange that has been decommissioned. I looked at the System Public Folders and found
replication is set up on "events root, OWAScatchpad, SchemaRoot, and Store Events. They are set to replicate to the old mail server. When I try to remove the old server from replication it gives me an error;
Microsoft Exchange Error
The following error(s) occurred while saving changes:
Set-PublicFolder
Failed
Error:
You must specify a value with the Replicas parameter.
OK
Not sure where to go with this error. Could someone point me in the right direction?
Thank you,
Wade HarrisHi,
For this issue, I recommend you add an Exchange 2010 public folder database to the replica list and then remove Exchange 2003 server from this list to check result.
I tested in my lab, and I got the same error with yours, we need to keep at least one public folder database in the replica list.

Can't change RUS in interop environment Exchange 2003/Exchange 2010
Hello!
We have interop environment with Exchange 2003 and Exchange 2010 Servers. We have many Exchange 2010 servers, and not so many days ago had a lot of exchange 2003 servers. So we moved all mailboxes from Exchange 2003 servers and started to remove exchange
2003 servers after that. Now it's all come to 2 Exchange 2003 servers. So what we have now:
Server 2003-A has replica of some Public folders, master in Routing group and a lot of other systems still use this server to send messages directly through SMTP.
Server 2003-B only assigned as exchange server in Recipient Update Service (RUS).
I wanted to change RUS properties from Server 2003-B to Server 2003-A and leave it as the last one, but it's impossible. I can't choose another server, can't even pick "Computers" in Objects during search. Also I can't create new RUS for the same
reasons.
Is there any possibility to change RUS from Server 2003-B to Server 2003-A or no at all?What if you click on the Advanced Tab and then Find Now...don't you find Server
2003-A when you do?

Hello,
I am working on an existing 2010 Exchange implementation. The site has one Exchange 2010 server with no other Exchange servers running and/or available. I looked through the application logs and I see multiple Event ID 5013 errors that state,
"The routing group for Exchange server <ServerName>.<DomainName>.LOCAL was not determined in routing tables with timestamp 6/24/2014 8:01:48 PM. Recipients will not be routed to this server."
I would like to know if by having this old 2003 Exchange server in AD, if it could be causing performance issues or if it is just a warning message only. I have located the old server name using ADSIedit under, "CN=Configuration,DC=<DomainName>DC=Local\CN=Services\CN=Microsoft
Exchange\CN=First Organization\CN=Administrative Groups\CN=First Administrative Group\CN=Servers". The old 2003 Exchange server is then listed in the right window pane so it could be deleted but I would need to know if this would effect the Exchange
environment other than removing the error from the event logs.
Thank you for your help,
MichaelHi,
When you install Exchange 2010 in an existing Exchange 2003 environment, a routing group connector is created automatically. If you remove Exchange 2003 from you environment, you should also delete this routing group connector.
Besides, here is a related article about Event ID 5013 which may help you for your reference.

Hello,
I am currently operating in the cloud fully, without any hybrid setup. But I have an old exchange 2003 server, from which I migrated to office365 still in the AD domain. I plan on fully removing it and any exchange organization information.
My question is, once I fully remove exchange 2003 org from my environment, including the attributes with it, is it still ok to use DirSync with password sync in order to sync passwords with Office365? My concern is that since I only have a standard
2003 domain (now without any exchange attributes), that the syncing could cause some changes in Office365. Since I have about 120 users operating for 2 years now fully in Office365, I need to ensure that nothing will be effected if I choose to setup
DirSync.
Any clearification and further documentation greatly appreciated.
Thank youHi,
Some additional info which can be good to clarify. As mensioned before, moving from Cloud Identies to Synchronized identities requires you to "match" your on prem Active directory users with the ones in the cloud. If that is not done properly,
you'll end up with duplicate users.
Here's a blogpost link on the topic that also includes a script that probably will help you on your way (will however not work if you don't have 2008R2 domain controllers without modification)
http://365lab.net/2014/04/18/office-365-migrate-from-cloud-identities-to-dirsync/.
Also note that from the moment you have started to use synchronized identities, as of now, you need to start manage alias email addresses and other attributes for your users in your local Active directory.
Hope this helps,
