Moving Exchange 2003 mailboxes to Exchange 2010

Hello
I have a new domain with Exchange 2010 server. I plan to join users to this domain but would like to know the best plan in moving the existing Exchange 2003 mailboxes over. Can I just import the PST files into their new Exhaneg 2010 mailboxes or is there
a better easier solution?
Thank you

Hi,
You can export mailbox using ExMerge in Exchange 2003, but ExMerge only supports ANSI PST files which have a 2GB limit.
To migrate mailboxes across forests, Active Directory Migration Tool (ADMT) will be used.
Here is a blog which can help you to do cross forest migration from Exchange 2003 to Exchange 2010 for your reference.

  • Is it supported to connect Exchange 2013 Mailbox using Exchange 2010 CAS in Co-existence?

    Hi Team,
    I am in the phase of upgrading Exchange 2010 to 2013, and introduced 4 MBX and 2 CAS of 2013 servers in co-existence.
    Only one production mailbox of 2010 moved to 2013. The owa of the mailbox moved to 2013, is working OK internally coz only internally configured, but when I configure outlook using 2010 settings, it got configured but when I open outlook it doesn't
    open and throws an error of some "cannot open set of folders".
    Is it supported to connect Exchange 2013 Mailbox using Exchange 2010 CAS in Co-existence? because I havnt configured 2013 CAS servers yet.
    Kindly share some KB or tip. Any help is appreciated. Thank You.

    I'll change Adam's wording slightly - you *MUST* install a CAS 13 server into every site where there is a MBX 13 server.

  • Migration from an exchange 2003 organisation A (Exchange 2003 sp2) to another Exchange 2010 organisation B

    Hello,
    We have two Exchange organisations:
    - A (Exchange 2003 SP2)
    - B (Exchange 2010)
    we want to migrate from A to B. the two organisations have to coexist during the migration (6 months). during this time the users have to share the same GAL and Calendar (Busy/Free informations).
    What are the steps to follow ?
    is there any docs/links treat this subject ?
    Regards

    Hi,
    You can use FIM for GALSYNC.

  • Exchange 2003 migrate to Exchange 2010 - single forest multiple domain. Active Sync problem

    Hi All, 
    I have AD single forest and multiple domain. for example, the forest domain is jakarta.co.id, and the other domain is bali.co.id.
    Exchange 2003 deployed in jakarta.co.id, User mail enabled in domain jakarta.co.id and bali.co.id.
    Then, I upgrade to Exchange 2010 (deploy in jakarta.co.id) and move mailbox from Exchange 2003 to Exchange 2010.
    All users in bali.co.id are able to access email from Owa, BlackBerry (BIS), Outlook, but cannot access from Android, Windows Phone. (Active-Sync).
    I got error information generated from https://testconnectivity.microsoft.com, as following:
    Attempting the FolderSync command on the Exchange ActiveSync session.
    The test of the FolderSync command failed.
    Tell me more about this issue and how to resolve it
    Additional Details
    Exchange ActiveSync returned an HTTP 500 response (Internal Server Error).
    Active-Sync still not work even I check option "Include inheritable permissions from this object" in security tab.
    any idea to fix this issue?
    Thanks.

  • Disable Exchange 2003 Mailboxes With AD Accounts En Masse

    Hello All,
    We are currently running Exchange 2003 - upgrading to 2010.  We have over 300 accounts that are innactive and looking to disable the AD accounts as well the associated mailboxes.  Does anyone have any advice on how to do disable both without using
    third party software?  I was going to use dsquery/dsmod to disable the AD accounts, but I didn't see much concerning the mailboxes.  Is there anything inherent to MS that can disable the innactive AD accounts and the mailboxes at the same time? 
    Unfotunately I'm new to Exchange and any help would be greatly appreciated.

    Hi,

  • The message could not be moved to the mailbox trash - Exchange Account

    Hi All,
    Not sure if it has anything to do with the update.
    Mail shows 1 unread message all the time, I've read it, still shows unread. I try to delete it and get the error "the message could not be moved to the mailbox trash", same error if I try to move it to the trash folder.
    Message has been long deleted from my actual INBOX via Outlook weeks ago.
    I've seen the suggestions to touch the trash settings under MAIL > Advanced, but there is no such option for Exchange accounts.

    I found an answer that has worked for me and others in another thread. It sounds pointless but just do it, all of a sudden I can delete mail now.
    1. Go to Settings
    2. Mail, Contacts, Calendars
    3. Click your email adress.
    4. Scroll down and click "Advanced"
    5. Click "Deleted Mailbox"
    6. Click "Spam" (at the bottom) then back to "Trash" (at the top).
    That's it. It should now work again.

  • Send E-Mails with large attachmenst with exchange 2003 Mailbox

    Hi!
    I have the following setting:
    Exchange 2003 for one Domain an two mailboxes with two different iPhones. One Mailbox/iPhone can send Mails with large attachments (500kB-5000kB) without any problems.
    The other mailbox has the problem, that i can only send with attachments sized about 50 kB. Larger Attachments are blocked by the phone and this mail stays in the Out queue.
    Has anybody a hint for me, where i can change this? I think it must be a user paramter, because one mailbox can send those large attachmenst. The Server it self must be ok - i think.
    Server: Windows 2003 with SP2; Exchange 2003 SP2
    Kind Regards
    Martin

    I agree with you - i think it must be a problem with the mailbox on the server side. But i don't know what to change there?
    I also configed on one iPhone those two mailboxes. One box can send large attachments - the other not.

  • Migrating from IIFP + Exchange 2003 to FIM + EXchange 2010

    Hello Everyone,
    hope you can help me figure something out 
    i had an IIFP Galsync synchronising users and contacts between 2 exchange 2003 environment and now i would like to switch to fim 2010 and Exchange 2010,
    from what i tried just exporting and importing the IIFP configuration to FIM 2010 works, but from what i know exchange 2003 is provisioned through vb code and exchange tools and exchange 2010 through remote powershell, is there anything to change in the
    original galsync extension code to enable exchange 2010 provisioning ? 
    thanks !!
    Hitch Bardawil

    Hi there Hitch
    The old IIFP galsync solution is obviously deprecated now, so I understand why you are wanting to convert it - but there have been too many architectural changes made in each of the components you're targeting to make any kind of conversion exercise realistic. 
    It is not an overly complicated scenario to handle in FIM, and as you point out the Exchange 2010 platform integration point is totally different and is even built into the MA itself (see
    Management Agent for Active Directory Global Address List (GAL)).  I suggest you have a trawl through old posts on Carol's blog
    to read about her take on what you are trying to do.

  • Exchange 2003 sp2 to exchange 2007 sp1 upgrade error

    Hi,
    We had Windows 2003 DCs and Exchange 2003 servers. We migrated AD DCs to windows 2008 R2 at parent domain.
    We have one parent domain and 10 child domains in remote sites .3 remote sites have been migrated to windows 2008 R2.
    Now at parent domain I am trying to install exchange 2007 SP1 on a server with windows 2008 R2 SP1. I am facing certain issues:
    1. When I run setup /PrepareSchema on this new exchange server , the organization check fails with error stating that : cannot find at least one DC running windows 2003 SP1 or later in DC=xyx,DC=com. This could be the result of moving DC objects in AD. Check
    that at least one DC running windows server 2003 SP1 or later is located in the "Domian Controllers" OU and rerun setup".
    2. When I try to install exchange server 2007 , I get the following 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.".
    Can any one shed light on this issue.
    Regards

    You cannot install Exchange 2007 SP1 on Windows 2008 R2 SP1 as it is unsupported.
    Only version of Exchange 2007 supported when OS is Windows 2008 R2 or R2 SP1 is Exchange 2007 SP3.
    Where are you installing Exchange ? child or parent domain ?
    2. When I try to install exchange server 2007 , I get the following 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.".
    Above error indicates that Exchange setup is trying to modify
    a version of an object which might have been created when organization is prepared for Exchange 2010. don't you have exchange 2010 Servers already in your environment ?

  • Migration; Exchange 2003 SP2 to Exchange 2013 on new Domain and DC

    I wasn't prepared for this task, and it was thrown at me to do...  Eyes are bleeding from planning reading and planning, would LOVE any input from you guys.  First time posting, here and have heard great things about these forums.  The Company
    I work for obtained a new client and a network that is in a cluster at the moment, so I'm having to dig through everything and restructure..
    Scenario:
    Old Domain/Server: (To be decommissioned)
    Server 2003 Standard SP2 (Domain: cosco.com; NETBIOS name: coscoex)
    Exchange 2003 SP2 (6.5.7638.1)
    Server is a domain controller and exchange server.
    Migrating to:
    Server 2012 R2 Datacenter (New Domain ad.cosco.com; NETBIOS name: cosco)
    VM #1: Server 2012 R2 Domain Controller at 2012 R2 Functionality 
    VM #2: Server 2012 R2 with Exchange 2013 Standard (Not Yet Installed) Joined to ad.cosco.com domain
    VM #3: Server 2012 R2 with Exchange 2010 (Not Yet Installed) joined to ad.cosco.com domain
    These are probably not ideal conditions, but I have to work with what I'm given.
    Host server (2012 R2) is in work group mode.  Hyper V Installed with a VM of Server 2012 R2 and as a DC at a functionality level of Server 2012 R2.  I had intended starting at a lower functionality level and raising
    it later, but.... ya I forgot to change it.  If needed I can spool up a new DC with a lower functional level.
    DNS, AD and group policy is all jacked up on the 2003 DC so that doesn't matter, All user accounts are going to be created under the new domain.  The concern is migrating the mailboxes from Exchange 2003 on the old domain to
    Exchange 2013 on the new domain.  The client is going to provide CSV of the AD accounts that are still valid (a lot of accounts are no longer used or are from people that no longer with the organization.)
    I had some ideas, but I'm not sure if they will work.  This is something I have never done before (Senior Engineer Quit).
    My thoughts:
    - Establish a two way trust relationship between the two domains.
    - Create two VM's, one with Exchange 2010 and one with Exchange 2013 (They have a 2010 licence that was not used).
    - Create the users on the new domain
    - Use the double hop method from Exchange 2003 > Exchange 2010 > Exchange 2013 
    - Link Exchange accounts to the correct user accounts on the new DC.
    Can this be done cleanly? Am I going about this the correct way?  Any feedback would be GREATLY appreciated.
    Note: We are forced to use ad.cosco.com (Obviously not the actual domain name)

    Hi,
    Base on my experience, your idea is feasible.
    However, before getting started, you should note that Exchange 2010 (with any service pack or update rollups) is not (yet) supported to install on Windows 2012 R2. More details refer to the following link: 
    http://technet.microsoft.com/library/ff728623(v=exchg.150).aspx
    After all the preparations complete, you can refer to the following articles to migration exchange 2003 to 2010, then to 2013:

  • Migrate exchange 2007 mailboxes to exchange 2013

    Hi Guys,
    im trying to move exchange 2007 mailboxes to 2013. to cut to the chase, is this possible because im getting different kinds of errors?
    Please advise if this is possible and how to do it.
    Thanks!

    Hi,
    Below link also will help you

    Before migrating exchange server, Make a plan
    try to practcice on lab. " Production environment and practice lab is entire different"
    I dont know your environment. Hope your Domain controller and Exchange environment is residing in same place. If it is different site, move FSMO roles to that site for installing purpose.
    IT is really challenge and excitement .
    Try to find the solution of client outlook connectivity,
    I had this problem, after I install Cumulative update, this problem gone.
     Login ECP console after install exchange server,
     Certificate installation,
    DNS pointing, port forward,
    Apply auto discover.
    I faced another issue as well during the installation. My ex admin upgraded exchange server 2003 to 2007. He may not uninstall exchange server 2003 properly. Exchange server
    2003 record was in active directory. Exchange 2013 doesnt suport mixed version of exchange 2003 and 2013. I have to delete the Exchange server 2003 record under DNS and Adsiedit. After that only exchange server 2013 allow to continue to install.
    Best of Luck " Nothing is impossible"
    Regards,

  • Exchange 2003, SBS Server, Outlook 2010, User Over Limit, 2 GIgs

    I have a user's who's account is over limit. I have recently done a clean install of Windows 7 Professional and Office 2010. I keep trying to have his computer archive old emails but in the process the machine keeps hanging. I try to crash out Outlook
    but the outlook.exe process will not let me shut it down telling me access denied. The only way to recover is to completely shut down the computer (which I cannot do VIA the regular shutdown option because of outlook hanging). What do I have to do to resolve
    this problem? Kind of urgent as it's affecting his receiving emails.
    Vern

    Hello,
    According to your description, the issue seems to be related to outlook profile or your PC. I recommend you check if the issue occurs when other users use the PC. If the issue doesn't occurs, it means your outlook profile should be problem.
    If the issue persists, please check if there is related error in application log.
    If there is any update, please free let me know.
