Exchange 2010 Hybrig configuration removal

Our Exchange environment currently consists of an Exchange 2003 and Exchange 2010 SP3 hybrid server. We were looking at moving all mailboxes from our Exchange 2003 server to Office 365 via the Exchange 2010 Hybrid server. Due to business decisions,
we have stopped our Office 365 deployment and are moving all mailboxes back on premise. With this in mind, I am looking for some guidance on how best to approach this.
Once all mailboxes are moved back on premise, would it be better to re-license our Exchange 2010 server and remove the Hybrid configuration then move all remaining 2003 mailboxes to the 2010 server or, build a new 2010 SP3 server and decommission
the Hybrid server.
Any advice would be greatly appreciated as I haven't found anyone who has gone this route before.

If the current server has the horsepower required to host your mailboxes and the other roles, I'd use it.  No reason to add complexity if it's not required.  If this server is underpowered, though, I'd remove Exchange from it before I added the
new Exchange 2010 server.  This will allow you to have a smoother experience in your migration process.  If you have configured your organization for hybrid operations (including legacyExchange names on certificates, etc), you should be able to just
point these to your Exchange 2010 servers (instead of to the cloud) to support your migration.  Make sure these changes are done before you start adding active mailboxes to the Exchange 2010 server, whichever one it is you start using.

  • Ramifications of assigning a wildcard certificate to the SMTP service (needed for Exchange 2010 Hybrid Configuration - Office 365)

    Hello All:
    I am receiving an error when I run the Manage Hybrid Configuration wizard - ERROR:Updating hybrid configuration failed with error 'Subtask NeedsConfiguration execution failed: Configure Recipient Settings. I have opened a SR, but figured I'd try the forums,
    too. I have a wildcard certificate from GoDaddy (MS says they support wildcards from GoDaddy) & that cert has only the IIS service applied to it on the CAS. I've read in the Exchange Server Deployment Assistant that it should have the SMTP & IIS services
    assigned to it, but my question is - SMTP on the CAS (separate server) or on the Mailbox/Hub Transport (separate server)? And what are the ramifications of assigning the SMTP service to, let's say, the CAS? We have had multiple issues every time the servers
    get updated/changed; I do not want to disrupt services further, as the Manage Hybrid Configuration will be done during business hours.
    If anyone can provide any assistance/clarification, it would be most appreciated.
    Thank you.

    Hi,
    We can enable a Wildcard certificate with SMTP service for Exchange Hybird Deployment. The SMTP service can be assigned to multiple certificates. For some Exchange services such as OWA, Ecp, ActiveSync, Autodiscover service, OOF, it is used with Exchange
    certificate with IIS service. And there is usually only one certificate can be assigned with IIS service.
    Please just make sure your Wildcard certificate can contain all namespaces which are used for all internal URL and External URL configuration in Exchange services. About how to import an existing wildcard certificate on the Exchange 2010 Hybird servers,
    please refer to the Import & Enable Third Party Certificate on Hybrid Servers
    part in the following article:

  • Exchange 2010 subdomain configuration

    Let me explain my situation as this is strange and I am baffled and new to this organization.  I work for a University and we have tons of email servers on campus.  Everyone has a  @university.edu email and account, but all the departments
    / colleges under the main university do their own thing.
    So that means I work for @dpt.university.edu and we have our own Exchange 2010 server.  Oh, and @university.edu is a Linux free something or another.
    We have been delegated the sub domain and manage our own dns they are secondary.  We have only 1 smtp on people's accounts (dpt.university.edu) but when people here send mail it is @university.edu.  When people respond it goes to @university.edu. 
    I have been having people configure a forward rule from university to dpt.university.edu and that works.
    So what am I missing?  Where else should I be looking?  I have not had to manage exchange since 2003.
    Thanks
    tim

    So that is a bit confusing.  I am sure main campus has an edge transport for their site, but we are not setup as a forest or affiliated what so ever.  Interestingly enough you send mail to dpt.university.edu the full mail name is displayed. 
    So we have 1 edge transport here at the dpt.university.edu, I cannot tell too much about central campus.  I feel like this could be a dns issue, but our dpt.university.edu has the mail subdomain with the mx record pointing to the smtp server. 
    I will admit I did not set this up, but it bugs me that I cannot figure it out.
    Tim
    PS HUH? I looked at the link and things look setup correctly not sure what more I need to do.

    Thank you for the reply, I have checked the applicationHost.config as indicated, and the path shown is the same as in the error message, there is no D:\Exchange,Server\V14\Bin\ path, it is as indicated in the error D:\Exchange2010\Bin\. Here is the section

  • Removing mailbox server from Exchange 2010 DAG - Node not fully cleaned up

    Hi,
    We are in the process of decommissioning some old Exchange 2010 servers. I have just attempted to remove one of our mailbox servers and have received a number of errors, related to its removal from the DAG.
    I have already removed the Public Folder replicas and all mailbox database copies. I then tried to evict the server from the DAG and received the following warning:
    I then ran the command that was recommended, from another server and in an administrative command prompt:
    I have looked in this log on both the server I ran the command on, a CAS server, and the mailbox server itself and can see no evidence of this error 2 that is listed here.
    If I run the Powershell command to look at the DAG I cannot see it there any more. I am assuming that this error message might only be an issue if I was planning on re-using this server somewhere else in Exchange or perhaps adding this server to another
    DAG. But I just want to decommission it.
    Can anyone put my mind at rest as to whether this is a genuine concern or not. If not my next step is to uninstall Exchange 2010 from this server and turn it off.

    Hi Belinda,
    I get the following:
    [PS] C:\Windows\system32>Get-DatabaseAvailabilityGroup
    Name             Member Servers                                                         
    Operational Servers
    DAG01            {WSR-EX-01, WSR-EX-101, WSR21}
    It doesn't look like that server is part of the DAG any more as far as I can see. I just can't explain that error message reported from the cluster command. As far as I can see the server is isolated. I already removed its database copies as a pre-requisite
    before removing it from the DAG as per this guide:
    http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_27039933.html
    I found a nice little script that gave reports on your Public Folder configuration and it highlighted that some of our folders were not being replicated properly across our mailbox servers. This helped me in removing these services from the server.
    It is currently doing nothing at this time as far as Exchange Services are concerned.

    Hi,
    If you have checked the permission, I suggest you checking the Membership Approval configuration.
    1. Closed the option “owner approval is required to join the group”
    2. Open the option “anyone can leave this group without being approved by the group owners”

  • 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.

    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:

  • Configure Exchange 2010 internal mail routing

    Hello,
    I’m have an Exchange server system which includes exchange 2003 standard edition server and an Exchange 2010 server standard edition server, plus a public SMTP server. Each exchange edition is on a separate machine. The SMTP server is on a separate machine.
    I am in the process of retiring the Exchange 2003 server per the following document:
    http://support.microsoft.com/kb/822931
    Inbound mail arrives at the SMTP server and is forwarded from there to the Exchange 2010 server. All user mailboxes have been moved to the Exchange 2010 server. There is a connector between the Exchange 2003 and Exchange 2010 servers. Both the Exchange 2003
    and Exchange 2010 server have a connector to the public SMTP server.
    In reviewing some of the log files, it appears that a lot of mail which originates from a user mailbox on the Exchange 2010 server is being sent from the 2010 server to the 2003 server and from there to the public SMTP server. I don’t know how to change
    this priority so that no mail will be sent to the Exchange 2003 server. At this point there is no reason for any mail to travel to or from the Exchange 2003 server. Any suggestions on how to change this configuration so that mail goes directly from the Exchange
    2010 server to the SMTP server?
    Thank you for taking the time to read and hopefully provide a response!

    Hi,
    From your description, I would like to clarify the following thing:
    If you have finished the migration successfully, and the Exchange server 2003 is unnecessary. You can remove the connector between Exchange 2003 to Exchange 2010 and the connector between Exchange 2003 to public SMTP server. And then the mail should go directly
    from Exchange 2010 to the SMTP server.
    Hope my clarification can be helpful.
    Best regards,

  • Removing Exchange 2007 from SBS 2008 (In an Exchange 2010 Coexistance Scenario) - In order to remove 2007 Mailbox Objects from Active Directory and remove the SBS2008 server completely

    I'm trying to remove Exchange 2007 from an SBS 2008 server
    (Server 2008 Standard FE).  My ultimate goal is to completely remove the SBS 2008 Server from the network environment.
    We have an Exchange 2010 Coexistence Scenario and Mailboxes/Public Folders/etc have been moved over to the 2010 mail server, on Server 2008 R2.
    I have moved all Shares, FSMO roles, DHCP, DNS, etc over to their respective servers.  We have two full blown DC's in the environment.
    I'm ready to remove Exchange 2007 from SBS 2008 and DCPROMO the server.  I can NOT seem to find a TechNet article that shows me how
    to proceed in this kind of scenario.  I am trying to use the TechNet article:
    http://technet.microsoft.com/en-us/library/dd728003(v=ws.10).aspx
    This article references Disabling Mailboxes, Removing OAB, Removing Public Folder Databases, then uninstalling Exchange using the Setup Wizard. 
    When I go to Disable Mailboxes I get the following error:
    Microsoft Exchange Error
    Action 'Disable' could not be performed on object 'Username (edited)'.
    Username (edited)
    Failed
    Error:
    Object cannot be saved because its ExchangeVersion property is 0.10 (14.0.100.0), which is not supported by the current version 0.1 (8.0.535.0). You will need a later version of Exchange.
    OK
    I really don't see why I need to Disable Mailboxes, Remove OAB and Public Folder Databases since they have been moved to 2010.  I just want
    to remove Exchange 2007 and DCPROMO this server (actually I just want to remove any lingering Exchange AD Objects referring to the SBS 2008 Server, using the easiest and cleanest method possible).
    Can someone point me in the right direction?
    Thanks!

    Hi,
    Based on your description, it seems that you are in a migration process (migrate SBS 2008 to Windows Server
    2008 R2). Now, you want to remove Exchange Server and demote server. If anything I misunderstand, please don’t hesitate to let me know.

    This Mailbox server is responsible for generating an Offline Address Book. Removal of the Mailbox role is not permitted
    If I move an offline Address book from Mailbox server1 to Mailbox server2 then I guess it should be okay?
    Also get below error msg as well, do I need to take care of anything else before I remove the mailbox server role ?
    Error:
    Setup cannot continue with the uninstall because the 'beremote' () process (ID: 2076) has open files. Close the process and restart Setup.
    Thanks !!!

    Hi Ms-2010,
    Before you uninstall the first Exchange 2010 Server, you need to fix few prerequisites warning/errors for a clean uninstallation.
    Four points should be considered:
    1. Change the OAB (Offline Address Book) generation role to other available server.
    2. Remove the server from DAG membership.
    3. Move the Arbitration mailboxes to another available Mailbox Server.
    4. Ensure that none of the databases are using public folder of this server as default and Move Public folder replica to other available mailbox server.
    Hope it is helpful.
    Best regards,
    Eric

  • Exchange 2010: Remove high available mailbox database error

    Hello everyone,
    I have a two node DAG exchange 2010 and recently split one mailbox database into two databases. 
    Now when removing the original database I get the following error:
    Please provide specific details.
    The following was done thus far:
    Deleted all softdeleted items
    this is not the default mailbox database
    Suspended the second mail server and removed it from mailbox, leaving now just one mail server attached to the mailbox database.
    Help

    Try to check mailbox import request is there or no by this command. Get-MailboxImportRequest. If you can see any requests listed. Remove it by this command Get-MailboxImportRequest | Remove-MailboxImportRequest.
    Thanks, MAS

  • ACE20 Module with Exchange 2010 Configuration

    Hello all,
    I have deployed the following configuration for Exchange 2010, if all services are up on the two servers it functions good but if a service goes down on one server (especially outlook) some clients are disconnected (stickiness) ...
    Stickiness is needed for all services by ip source sticky and by coockies for OWA.
    Because all services are on the same server (ip address) the configured sticky causes problems !!! when a service is down the ACE usually forwards  requests to it !!!! Any help please.
    Configuration :
    XXXXX-ACE1/CTXT-EXCHANGE(config)# do sh run
    Generating configuration....
