Is Exchange 2003 Uninstalled?

I recently did a migration from Exchange 2003 to 2010. Everything seems to be working. After having the 2003 server shut down for a week or two with no issues, I decided to uninstall it.
After a few issues with remaining mailboxes etc, the uninstall process via Add/Removed ran. I had one error during the uninstall but unfortunately I didn't write it down. I believe it said something the effect of an error with messaging or something.
After click past that, the uninstall proceeded. If I now go into Add/Remove, the option for MS Exchange is no longer there however some of the services are still on the server, specifically the System Attendant and Exchange Management and they were running.
I have stopped and disable all Exchange services.
So my question is - how can I be sure it has uninstalled correctly and what are the ramifications if it didn't? Everything seems to be working but I just have this feeling that something is still left out there and things weren't completely cleaned
up.
Thank you for your help.

Agree with ExchangeITPro to see if ExBPA gives any error.
If Exchange 2003 Server object is removed from AD (Under configuration partition) then I wouldn't worry about it.
Open ADSI Edit, expand Configuration, expand CN=Configuration,CN=<domain>, expand CN=Services, expand CN=Microsoft Exchange, expand CN=<Exchange organization name>, CN=Administrative Groups, cn = CN=Exchange Administrative Group (FYDIBOHF23SPDLT),
CN=Servers, If Exchange 2003 server is not listed here then Uninstaller should have uninstalled it properly...

Error in uninstall Exchange 2003 after Exchange 2010 migration.

Setup encountered an error while checking prerequisites for component "Microsoft Exchange": 0X80072030 (8240): There is no such object on the server. I searched about the error and most of the hit is referring to postmaster account point
to the old server and that doesn't apply to our environment.
http://support.microsoft.com/kb/283089
below is the errors from the setup log. Other users had reported this problem but didn't find any solution other than manually uninstall the last Exchange 2003 server.  The problem is I couldn't find any official KB for manually
remove legacy Exchange server from Exchange 2010 org, bb288905 or kb833396 do not provide enough information. So is my only choice is to call Microsoft Support?
thanks

Did you also check for other accounts, i.e. non-postmaster?
Setup will check to make sure that there are no mailboxes homed onto this server.    This attribute homeMDB could still be set for a mailbox that has the Exchange attributes remove. Seen that before when people set attributes directly
via scripts.....

Yes, I did. Nothing has MDB = the legacy server.    The error from setup log seems to suggest a different problem.

Cannot Uninstall Exchange 2003 from former SBS2003 server

Hi,
I have this problem uninstalling Exchange 2003 from a prior SBS2003 installation.
Started with SBS2003 with Exchange2003 on server1
Then added server2, with Exchange2003 Standard
Then transitioned succesfully Server1 from SBS2003 to Server2003 Standard with Exchange2003 standard.
Now I have added 3 Exchange2010 servers and migrated completely to Exchange2010.
Uninstallation of Exchange2003 Standard from Server2 went succesfully.
I cannot find a way to uninstall the last Exchange2003 Standard from Server1
In Control Panel add remove programs there's no option to enter SBS setup anymore.
When starting setup.exe from SBS CD2 (i386 directory) I'm asked for a Product Key but I have no valid key to enter. Tried SBS key, Transition key, nothing works.
When downloading an Exchange2003 SP2 installation exe I only have the option to upgrade the existing installation. No option to uninstall.
What is the way forward? I'm stuck right now.
Regards,
Joost

Hello,
If you don't uninstall exchange 2003 in Control Panel add/remove programs, you may need to uninstall it by ADSIEDIT. Do not remove this Administrative Group unless you’re absolutely sure there’s
no object in Active Directory referencing this Administrative Group in the ExchangeLegacyDN attribute.
More information for your reference.

Uninstall/Reinstall Exchange 2010 in coexisting Exchange 2003

Hi,
Can we uninstall Exchange 2010 without any affect to Exchange 2003 in the co-existing environment? I installed Exchange 2010 in existing Exchange 2003 and tried to configure for both Exchange exist in our domain. Somehow the Exchange 2010 crashed
and now it cannot start, only stuck in Initializing process. I want to uninstall and then reinstall but I don't know if doing this will cause any problem to the Existing Exchange 2003. Could someone tell me?
Thanks,
Jim

You don't have to uninstall and reinstall server, just rebuild base server with OS with what it had earlier and recover Exchange 2010 with /m:recoverserver switch.
Recover an Exchange Server
I assume you still have Exchange 2010 database backup or original files for restore if needed and this is just OS crash and can not be repaired scenario

Uninstalling Exchange 2003 from Additional DC

Hello,
We have an old exchange 2003 installed on additional Domain Controller. We have already moved all the mailboxes to exchange 2007 server. Now we would like to uninstall exchange 2003 from Domain Controller.
Will Domain Controller have any problems when we try to uninstall exchange 2003 ?
http://www.arabitpro.com

Hi syed,
Thank you for your question.
If all services which are on Exchange 2003 have migrate to Exchange 2007 and run without any problems for a long time, we could uninstall Exchange 2003 from control pane.
If there are any issues after you uninstall Exchange 2003; welcome to our forum for help.
If there is a reminder there is previous Exchange in organization when you deploy Exchange 2013 in the future, we could navigate the follow path to delete Exchange 2003;
Run ADSIEDIT.msc in RUN;
Navigate Configuration[domain.com]>service>Microsoft Exchange>domain>Administrative Groups>Exchange Administrative Group>Server;
Then we find the previous Exchange server and delete it.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

IPhone 3G will not sync with Exchange 2003 after updating to 4.0.1

I keep reading a lot of posts about users who updated to 4.0 not being able to get Exchange to sync and 4.0.1 was supposed to fix that however I just updated from 3.something to 4.0.1 and now my Exchange 2003 server email will not sync (kind of) and my Contacts are slowly disappearing.
I tried to delete and re-enter the exchange account however after 5 hours I only have about a dozen emails out of the hundreds that should be there. Also the contacts that were there are now slowly disappearing.
I saw somewhere that I should try to access www.myserver.com/oma and www.myserver.com/exchange to see if I can log in there. I am able to get into OMA without an issue however when I go to /Exchange I am able to login and get the left window pane to start (inbox, contact, notes, etc buttons), but no other pane has anything.
I don't know if this is related, but I did notice that on some sites that use script for the menus I am no longer able to navigate the menus. They drop, but clicking a link in the menu does nothing.
I have another 3G that is working fine with the 4.0.1 and all the BB and Windows Mobile and Droids are working fine.

You know, yesterday I deleted the entire Exchange account, rebooted, added it -- nothing... then I deleted it again, rebooted again, etc... after about the 3rd time of doing this and allowing the Internet Accounts to automatically discover the account, it started working again.
You might want to give it the brute-force-angry-uninstall-and-reboot-multiple-times-while-shaking-angry-fists -and-cursing routine and see if that helps you!

Exchange 2003 to Exchange 2010

We have about 18 sites and most of them have been migrated to Exchange 2010. I'm trying to uninstall Exchange 2003 on the legacy servers but I am running into an issue with the routing groups. Since the server is the master member under the routing group
I am unable to uninstall exchange 2003. All the documents that I could find are in regards to removing the last exchange 2003 server from the org and these will not be the last servers to be removed but they are the last in their sights. I have tried deleting
the connector from exchange 2010 then from exchange 2003 and I can't because it contains a member server and I can't delete that member server because it is a master and every doc that I can find wants me to replace the master but I want the RG to completely
go away! This should not be that difficult. Any advice would be greatly appreciated.
I know this is in the wrong form but there isn't a way to select Exchange 2003 or Exchange 2010 so I apologize about that.
-J

Hi,
I think you only need to remove the RGC:

Exchange 2003 Removal fails w/ Error code 0X80072030 (8240): There is no such object on the server- pls read

Dear all,
I know there are quite some threads regarding this issue. But I've been looking at all of them w/o any solution for my problem. Here we go...
I've followed all instructions for a Exchange 2003 to 2010 transition. All went fine to the point I'm trying to uninstall Exchange 2003 via Control Panel/Software/Remove. So far I did the following:
1. Move mailboxes to Exchange Server 2010 using Move Mailbox Wizard or Powershell => successfully
2. Rehome the Offline Address Book (OAB) generation server to Exchange Server 2010 => successfully
3. Rehome Public Folder Hierarchy on new Exchange Server 2010 Admin Group => successfully
4. Transfer all Public Folder Replicas to Exchange Server 2010 Public folder store => successfully
5. Delete Public and Private Information Stores from Exchange 2003 server => successfully
6. Delete Routing Group Connectors to Exchange Server 2003 => successfully
7. Delete Recipient Update Service agreements using ADSIEdit according to
http://technet.microsoft.com/en-us/library/bb288905(EXCHG.80).aspx => successfully
8. Uninstall all Exchange 2003 servers => fails with "Error code 0X80072030 (8240): There is no such object on the server"
I used the following articles while migrating to Exchange 2010:
http://technet.microsoft.com/en-us/library/bb288905(EXCHG.80).aspx
http://support.microsoft.com/kb/833396/en-us
http://www.simple-talk.com/content/article.aspx?article=882
and several more.
I looked into these forums regarding my problem and came up with:
http://support.microsoft.com/kb/283089/en-us
http://support.microsoft.com/kb/822931
I investigated the following possible reasons:
- homeMDB attribute (no references to my Exchange 2003 anymore)
- HomeMDBBL attribute (as described here
http://social.technet.microsoft.com/Forums/en-US/exchangesvrmigration/thread/f0e3edd7-34e5-46b8-8061-1991aaffc30f) (no Information Stores available anymore as they have been successfully removed)
- msExchHomeServerName attribute (all pointing to my new Exchange 2010 server)
- the "famous" postmaster issue as described here:
http://support.microsoft.com/kb/283089/en-us (pointing to the new Exchange 2010 server)
In order to investigate all attribute related issues a utilized a VBS script resulting in an Excel sheet I was easily able to filter:
SET objRootDSE = GETOBJECT("LDAP://RootDSE")
strExportFile = "C:\temp\MyExport.xls"
strRoot = objRootDSE.GET("DefaultNamingContext")
strfilter = "(&(objectCategory=Person)(objectClass=User))"
strAttributes = "sAMAccountName,msExchHomeServerName,homeMDB,legacyExchangeDN,givenName,sn," & _
                                "initials,displayName,physicalDeliveryOfficeName," & _
                                "telephoneNumber,mail,wWWHomePage,profilePath," & _
                                "scriptPath,homeDirectory,homeDrive,title,department," & _
                                "company,manager,homePhone,pager,mobile," & _
                                "facsimileTelephoneNumber,ipphone,info," & _
                                "streetAddress,postOfficeBox,l,st,postalCode,c"
strScope = "subtree"
SET cn = CREATEOBJECT("ADODB.Connection")
SET cmd = CREATEOBJECT("ADODB.Command")
cn.Provider = "ADsDSOObject"
cn.Open "Active Directory Provider"
cmd.ActiveConnection = cn
cmd.Properties("Page Size") = 1000
cmd.commandtext = "<LDAP://" & strRoot & ">;" & strFilter & ";" & _
                                   strAttributes & ";" & strScope
SET rs = cmd.EXECUTE
SET objExcel = CREATEOBJECT("Excel.Application")
SET objWB = objExcel.Workbooks.Add
SET objSheet = objWB.Worksheets(1)
FOR i = 0 To rs.Fields.Count - 1
                objSheet.Cells(1, i + 1).Value = rs.Fields(i).Name
                objSheet.Cells(1, i + 1).Font.Bold = TRUE
NEXT
objSheet.Range("A2").CopyFromRecordset(rs)
objWB.SaveAs(strExportFile)
rs.close
cn.close
SET objSheet = NOTHING
SET objWB = NOTHING
objExcel.Quit()
SET objExcel = NOTHING
Wscript.echo "Script Finished..Please See " & strExportFile
What I did find is that all my Exchange enabled users have an legacyExchangeDN attribute that is still pointing to my Exchange 2003 organization:
e.g. "/o=First Organisation/ou=First Administrative Group/cn=Recipients/cn=Administrator"
Could this cause any problems?
Now the in depth look into my "Exchange Server Setup Progress.log":

I kept on searching and found something else:
http://www.outlookforums.com/threads/33038-cannot-uninstall-Exchange-2000
It says that the following groups need to be resided in the AD's default "Users" organizational unit:
- Exchange Domain Servers
- Exchange Enterprise Servers
- Exchange Services Group
Unfortunately I cannot find the "Exchange Services Group". Does that have something to do with my problem?
Furthermore I found out that the Exchange 2003 has been originally installed with SBS 2003 back in time. The SBS 2003 has then be migrated to a regular Windows Server 2003 infrastructure with 2 DCs. But there still is a load of stuff reminiscent of SBS
2003 within the AD.
Then I dug deeper into my AD using ADSIEdit. I found another attribute homeMTA that is pointing to a corresponding Exchange server. After adjusting my aforementioned VBS script a was able to look into that attribute as well. I found 2 users pointing to my old
Exchange server within their homeMTA attribute.
Furthermore I saw that when trying to uninstall Exchange 2003 there is no path to my installation anymore. It's empty:
Another issue?

Running Unity with both Exchange 2003 and 2010?

My company is planning to upgrade from Exchange 2003 to 2010. We are
currently using Unity 7.0. We'd like to run the two in parrallel for a bit and take our time switching users over.
Now I've read that Unity can support Exchange 2010, but I haven't found anything about running Unity using both Exchange 2003 and 2010 in parrallel.
Is this something Unity can handle?

We're doing something similar, but we have an in-place Unity 7 and Exchange 2003 environment; we are putting some users from an org we support on an Exchange 2010 server, but do not want that to be the partner server (yet). The instructions seem to point you to making 2010 the partner; I'm wondering why Step 13 (of your link) we are uninstalling the Exchange Server 2003 System Management Tools, if it’s a mixed environment and 2003 will still be the partner server. I also saw somewhere that you don’t have to move the unitymsgstoresvc account to Exchange 2010 if you are in a mixed environment. Is that true? Thank you.

Remove Exchange 2003 Problem

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 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.

Zikorai,
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.

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
Name                Site                 ServerRole Edition     AdminDisplayVersion

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.

Get-RoutingGroupConnector shows nothing. 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:

Exchange 2013 finds an old Exchange 2003 server

We have a new MS Server 2012. We are trying to install Exchange 2013
We migrated from an MS SBS Server 2003. We migrate AD over. The SBS 2003 is no longer on the network.
When I try to install Exchange 2013. I receive an error.
Error:
One or more servers in the existing organization are running Exchange 2000 Server or Exchange Server 2003. Installation can't proceed until all Exchange 2000 or Exchange 2003 are removed.
Any and all help is appreciated.

The correct supported method I believe is to ensure that you uninstall the old Exchange server from SBS as part of the migration, before you demote the SBS server and remove it from the domain, otherwise you end up with old records remaining in Active Directory.
If you still have the old SBS server available and it hasn't been demoted then have a look at the steps listed here
http://technet.microsoft.com/en-us/library/gg563804.aspx
If that's not possible the other option is to remove the old records via ADSIEdit as detailed here
https://social.technet.microsoft.com/forums/exchange/en-US/46ca107c-7ece-4da7-8aea-46b705793f37/removing-old-exchange-and-installing-a-new-one however you should be aware that while it reportedly does work this is not a supported method.

Is Exchange 2003 Uninstalled?
