Exchange 2003 to 2010 OWA redirection

Hello,
We are currently migrating from current exchange 2003 environment to exchange2010.
For today we installed new ex2010 server with CAS/HUB/MBX roles. Before we start moving mailboxes to new server we have to setup both OWA's on both servers.
During transition user have to use OWA regardless on which mailbox server user mailbox is located.
Today when user wants to open Owa he types https://exchange.domain.com/exchweb/bin/auth/ and webpage opening, but of course if i move such account to exchange 2010 mailbox OWA not opening (blank page with address https://exchange.domain.com/exchweb/bin/auth/owaauth.dll).
I have readed about -echange2003url in exchange 2010 but i don't know how to implement it.
Besides I suppose that during transition 2 OWA's aren't avaliable at the same time in internet if I do not have second public ip ? but like i mentioned above there is a way to redirect ex2010 account through 2003 url ?
One more thing, i have setup on exchange2010 internal/external URL to exchange 2003 current address https://exchange.domain.com/exchweb/bin/auth and also "-exchange2003Url" too and now when i want to logon on a mailbox which is located in ex2010
then now OWA ex2010 showing up and i can enter one more time credentials and finally open mailbox via Owa. But if i wanto do it from internet then blank page shows (https://exchange.domain.com/exchweb/bin/auth/owaauth.dll)
Thank you in advance for any suggestions.

Hi,
According to your description, you have just configured OWA URLs on Exchange 2010 server as what you did on Exchange 2003. And the URLs on two servers are same. If I misunderstand your meaning, please feel free to let me know.
If yes, I recommend you check the following configurations:
1. There is a legacy namespace for your Exchange 2003 server.
2. Public DNS entries: legacy.domain.com points to your Exchange 2003 server IP address; exchange.domain.com points to Exchange 2010 IP address
3. Configure the URLs on Exchange 2003 server with the name legacy.domain.com
4. Configure the property Exchange2003URL on OWA virtual directory of Exchange 2010 server.
For more information, you can refer to the following article:

Exchange 2003 to 2010 Migration Active-Sync & OWA

I am in the process of migrating from Exchange 2003 to Exchange 2010. I have a co-existence running currently. I have moved 1 mail box over to the new exchange server (a test account I created). I have 2 questions, one about OWA and the other about Active-Sync/Mobile
access.
1. When I log into my internal OWA site I can access the webmail just fine. However when I try to go to my external OWA site I get a HTTP Error 404. I have setup the weblink https://webmail.company.com in my external DNS record. However the internal link
says it is https://webmail.company.com/owa. Is there something additional that needs to be setup in IIS for the external site to work or only after the migration is completed?
2. I tried adding the account I migrated to my cell phone for mail but I just get a "Connection to server has failed" message. The internal and external link for mobile access is both the same and setup in external DNS https://mail.comapny.com.
Is this a feature that only works after the migration is completed? I have ports 80,443,143,25,993 open in my sonicwall for e-mail services. However the IP is still set to my old exchange server. Is it possible to have 2 settings the same in sonicwall with
2 different IP's? Last time I tried it with migrating my VPN neither VPN server worked after that.
Any help and insight would be greatly appreciated. I am new to systems administration and this is my first exchange migration

Hi,
Here are my answers you can refer to :
1. To deploy OWA in the Exchange 2003 and 2010 coexistence, we need a legacy namespace for the Exchange 2003 server.
For more information, you can refer to the following article:
http://blogs.technet.com/b/exchange/archive/2009/12/02/3408921.aspx
Additionally, for the 404 error, I recommend you check the IIS log to find the root cause:
http://support.microsoft.com/kb/943891
2. I recommend you deploy Exchange 2010 in the "Internet Facing AD Site" and Exchange 2003 server in the "Non-Internet facing AD site": set the external URL in CAS 2010 and point mail.company.com to Exchange 2010 server IP address.

Public folders are not in sync after settting up Replicas between Exchange 2003 and 2010

I have setup Public Folder replicas between the 2 Exchange servers and I can see all the top and sub level folders.
For those mailboxes that were migrated over to Exchange 2010, I have noticied a lower number of item contents in these fodders when views from an Outlook client whose mailbox had been migrated over to Exchange 2010.
On Exchange 2003 System Manager, if I properties one of the Public Folders, under the Replicataion tab, I can see the old and new server there. On the Exchange server 2003 box, I can see the last update reviced was a few weeks ago.
I did see an option to synchronize content but I am not sure which server to run this one from. The Exchange 2003 or 2010 server.
There is also a Resend Changes... option. Should I use this instead?
Can anyone advise?

Hi,
The "Resend changes" and "Synchronize content" options in Exchange 2003 ESM are used to initiate hierarchy and content replication.
To update public folder hierarchy and content from Exchange 2010 side, you can use the following commands.
Update-PublicFolderHierarchy
Update-PublicFolder
Please run the Get-publicfolderstatistics cmdlet to get public folder details such as item count, this information will help you compare content replicated between the source and destination servers.
Besides, here is a blog about public folder replication troubleshooting for your reference.

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.

Migrating exchange 2003 to 2010 while everyone is running SMTP, POP3 and IMAP on the old exchange 2003

Hi all
We have a legacy Exchange 2003 running with more than 800 users and with a very mixed configuration for client access. Most of users are running POP3/SMTP on the Exchange, some are running IMAP/SMTP and some are running MAPI access.
Please note that THERE IS NO WAY that we move all users to MAPI access before the installation (due to deadlines).
We plan to install a new Exchange 2010, starting with a CAS/HUB server. We do not need to migrate users automatically, and we can proceed later to move them individually to the new Exchange 2010 infrastructure in a non-transparent way.
More importantly, we need to maintain that everyone receives their e-mail and all communication through the exchange 2003 continues uninterrupted.
My question is can we install the new CAS/HUB server, while maintaining the old exchange server running with it's old name and create new names for the CAS/HUB server. In such a configuration, will all the Exchange 2003 services continue to run as usual
(POP3/IMAP/SMTP/MAPI)?

In addition, you may also spend some times at below mentioned helpful resources to check the prerequisites before moving all mailboxes from exchange 2003 to 2010 :

Moreover, to avoid any interruption during the completion of migration process, you can also take a look at this application(http://www.exchangemigrationtool.com/) that could be a good alternate approach
for you.

Exchange 2003 to 2010 migration issues

Hello,
I have installed exchange 2010 in my legacy 2003 environment six months ago.
i have moved all the mailboxes, Public folders to exchange 2010 and created routing group connectors between 2003 -2010.
now unfortunately the legacy server got crashed. now the problem is we are unable to receive emails.
Can somebody help on this.
Thanks,

Exchange 2003 to 2010 migration move public folder

Hello.
I'm on the road to Exchange 2010 migration and stuck at on question
All tutorial says then you want to replicate system PF and Public Folders you need to add PF 2010 in ESM and set replication to Urgent,that's all
But then i view my system PF replication on Exchange 2010 i see checkbox Use public folder is checked and replication shedule on Exchange 2010 is set to Never run(greyed out)
Is this right? Or i need to uncheck it and then shedule is set to Always run automaticly?
Do i need to do it for all PF? (system and non-system)?

Hi stevemaystr,
Don’t worry about the replication of PF, we can use the MoveAllReplicas.ps1 and ReplaceReplicaOnPFRecursive.ps1 script to move all public folder and all replicas to another database, please refer to:

Exchange 2003 + Outlook 2010 hangs if deleted shared mailbox exists into profile

Environment - Exchange 2003 + Outlook 2010 published via Citrix
We recently did the cleanup of shared mailboxes which are no longer needed. However post our activity we found that many users are reporting that their Outlook is hanging for a long time during startup and it continues while working on outlook. Upon investigation
we found that their Outlook profile was having 1 or 2 shared mailboxes listed which were deleted from organization. As soon these shared mailboxes were removed from profile the Outlook started working fine.
Is this know issue of Outlook and if any hotfix available for same, I have already checked the 'download shared folder' option which isn't selected.

Hi,
Maybe the issue is related to the default behavior in Outlook.

Exchange 2003 to 2010 Migration and Certificate Issue

Good Day All -
This is my first post on here, so if I post to the wrong spot or something is incorrect, please forgive and redirect me.
I have a small working knowledge of Exchange and even less about Certificates.
I did an Exchange 2003 to Exchange 2010 migration last weekend, and, for the most part, everything went well. Initially when users first launched Outlook for the first time, (post mailbox move), the received a Security Alert to install the Self-Signed
Certificate for the new Exchange Server. This was a one time deal and everything was good after that. Also, I exported the non-self-signed certificate, (for external mail, purchased from Network Solutions), from the Exchange 2003 Server, and imported
it into the Exchange 2010 Server. Again, no issue.
Jump ahead to today. It was brought to my attention that some mobile devices were unable to connect, and in my infinite wisdom ,<sarcasm>, I thought the issue had to do with the certificate(s). I started troubleshooting and it seems like I've
fixed the the mobile devices being able to connect, but now every time users launch Outlook, they receive the Security Alert for the non-self-signed certificate, over and over again. (or it just pops up while connected to Outlook)
They go through the motions of installing it, but it just keeps coming back.
I have referenced several articles on here, and other sites, but nothing has worked and I'm stuck and fried on this one.
http://support.microsoft.com/kb/940726/en-us
http://exchangeserverpro.com/how-to-issue-a-san-certificate-to-exchange-server-2010-from-a-private-certificate-authority/
Would someone please help. Thanks very much, (in advance).

Thanks for the reply. Yeah, I have read many articles, (especially from exchangeserverpro), and have learned alot, but I am definitely a cert novice here.
The cert "error" on my internal Outlook Clients is a Security Alert for
mylocalservername.mydomain.lcl. When I click to view this certificate it points to
webmail.mydomain.com, which is what the external
devices use for SSL verificartion.
I'm not understanding why my internal Outlook clients are prompting for this external certificate.
I have the self signed certificate that auto-installed with Exchange 2010, which points to the DNS Names:
mylocalservername.mydomain.lcl and mylocalservername. This was the server certificate that the Outlook clients installed after they launched Outlook post mailbox migration to the new Exchange
2010 server and everything was good internally.
For my external connection then, I exported the webmail.mydomain.com
from the old Exchange 2003 server, and imported it on the new Exchange 2010 server; (EMC\Server Configuration\Import Exchange Certificate (Actions Pane)). Ever since doing this, all Outlook clients, (2007 & 2010)
receive the Security Alert for mylocalservername.mydomain.lcl, but is for the
webmail.mydomain.com cert.
I have two certs on the Exchange 2010 server; one self signed and one not, (The non-self-signed purchased from a CA and thus the one I imported from Exchange 2k3).
The services assigned to the two certs are:
Self-Signed, (mylocalservername.mylocaldomain.lcl and
myservername):
IMAP, POP, SMTP
Non-Self-Signed, (webmail.mydomain.com, Purchased from CA)
IIS
Please let me know if there's anything glaring here that I'm missing, and if not, what you think the problem may be. Thanks very much.

Exchange 2003 to 2010 Migration

Hello,
I seem to have ran into issues with Default GAL, default address lists, email address policies, OAB, etc.
Background: Exchange 2003, with one FE and one BE server with multiple domains for mail access. We decided to migrate to 2010 and have one hyper-v server with 3 VMS running AD, CAS/HT and MBX roles respectively. All the AD preparations and installation (exchange
2010 Sp2) of CAS/HT role was smooth. When I installed the MBX role it was successful but could not see Public Folder Database and was unable to create one because of AddressList errors and had to be upgraded to 2010. Since there were multiple domains, LDAP
filter were used and those had to be updated with OPATH filters and I used the "ConvertFrom-LdapFilter.ps1" script to convert and upgrade to 2010. I could do this for all the custom address lists but it did not run for "All Users", "All
Groups" "All Contacts" as it says ADObject cannot be found on exchange2003 server.
I created a test mailbox on the new server and could login using OWA but cannot see GAL or search for addresses. I could send and receive email from 2010 to both 2003 mailbox & external domain with no issues. I did configure the CAS role with legacy
URL (existing OWA URL https://myweb.domain.net/exchange) for exchange2003 and a new URL (https://mymail.domain.net/owa) for exchange 2010 and also enabled Outlook Anywhere, MS Active Sync, etc. But I cannot setup outlook using autodiscover or even manually
by providing the info. I have to start migrating users and this has become a big show stopper and would appreciate if anyone could help/guide me through this to troubleshoot/fix the issues and move the mailboxes ASAP.

Hi SyedSF,
From your problem description, it seems that you have a permission problem here. Maybe you have had Address List Segregation configured in Exchange 2003 and that is not supported in Exchange 2010.
I recommend you to use ADSIEdit to check the permissions on "All Address Lists", "All Global Address Lists" and "Offline Address Lists". Include inherited permissions should be checked and "Authenticated Users" should have the permissions read and "Open
address list".
What's more, here are some similar threads for your reference.

Migration Exchange 2003 to 2010 routing connector

Hello
At least we deside to migrate from 2003 to 2010 Exchange now i'm preparing and stuck around one question.
In our Exchange 2003 organization we have couple backend servers and one frontend on which OWA is installed.
OWA server placed to second routing group others backend server in first routing group.
Roitung group connected to each other by connector.
So the question - when i install CAS Exchange 2010 he asked me with which Exchange 2003 server i want to create connector - which server i should choose? Backend or Frontend which placed in different RG?

It doesn't really matter, it is a connector between your 2010 and 2003 servers.
You can choose the backend servers as it will reduce one hop in your case. Do make sure that you make the connector redundant by adding atleast two 2003 and 2010 servers as source and target servers in both connectors.
There will be two connectors - one from 2003 to 2010 and another from 2010 to 2003.

Exchange 2003 / Outlook 2010 autodiscover

Exchange 2003 as part of 2003 SBS
Outlook 2010
After changing the default e-mail domain from one domain to another (e-mail for both domains hosted on our in-house Exchange 2003 server), already-configured Outlook 2010 Exchange clients are now popping up this message at startup and periodically during
the day:
Allow this website to configure [UserName]@[MyDomain].com server settings?
https://autodiscover.bluehost.com/autodiscover/autodiscover.xml.
The username with the message is [email protected] The user was originally configured as
[email protected] Both are still hosted on our in-house Exchange server. The users can still use their mailboxes, but this message keeps popping up.
None of the auto-discovery registry entries refers to BlueHost, and there is no auto-discover record on my local DNS server. Bluehost just happens to be where our internet domain is hosting, although we have MX records redirecting e-mail to McAfee's anti-spam
service that then forwards them into our in-house Exchange server. That is, BlueHost has nothing to do with our Exchange clients.
The user checks the box to quit notifying, then clicks Cancel, and things just repeat. Clicking OK just adds the BlueHost address to the list of redirect servers in HKCU\oftware\Microsoft\Office\14.0\Outlook\AutoDiscover\RedirectServers. That, of course,
does no good because BlueHost has nothing to do with our e-mail past providing the MX records.

Hi,
It's a bit weird, based on my knowledge there is no AutoDiscover feature in Exchange 2003 - It started with Exchange 2007. The provided information all implies it's related to AutoDiscover, could you please confirm this first?
Also, I think this issue is more on Exchange side, if so, it's better to post the question in Exchange Server forum to get more dedicated support:

Exchange 2003 to 2010 migration mailflow issue

Hello,
I have a server 2003 w/ exchange 2003 that we are upgrading to 2010 to support Outlook 2013.
So we installed a windows 2008 server and exchange 2010. We followed a guide to help with the different steps and didn't have problem or error until now.
So what we have right now, is exchange 2003 with still ALL mailboxes.
Replications of folders is done.
Policies are updated.
The firewall is forwarding port 25 to the new exchange 2010 server:
Emails are coming in fine.
Internal emails are also perfectly fine (from internal user to internal users).
the only thing that is giving us trouble is the emails coming out. None of them are going out and they are getting "stuck" in the "routing group connector" on the 2003 machine.
The 2010 exchange has a simple send connector set SMTP/* with this server as source. The 2003 exchange only had the exch2003-exch2010 connector.
Because emails were kind of accumulating (80+) I decided to take the send connector on the 2010 exchange out. and added back a send connector on the 2003 exchange. This kind of "fixed" it as now all emails are going just fine. It also fixed
the queue as part of it got liberated when I added the 2003 send connector.
I still have 25 emails stuck in this "routing group connector" that I'd like to take care of.
We are obviously not done with the migration and this coexistence phase as actual mailboxes still need to be moved.
So I'd like to take care of this queue in the routing group connector as well as continue the process of being able to receive and send from the 2010 machine only. then I would continue the migration process.
FYI, the 2003-2010 connector was created using power shell on the 2010 machine. I am not using any smarthost.
and the error message (in the queue) I get is: "unable to bind to the destination server in DNS"
FYI, my 2003 server is called "SERVER1" and the 2010 server is "SERVER2", they're on the same local domain company.local.
FYI (not sure if that's relevant), the server1 exchange has a different certificate (different domain name) than the new server (server2) as our web host finally allowed us to use subdomains. not trying to confuse anyone but I am really stuck there and maybe
this is related: certificate for the exchange 2003 machine: www.company-mail.com (only 1) and certificates for the exchange 2010 are: mail.company.com / autodiscover.company.com (and a legacy.company.com we may not need since the actual coexistence phase will/should
be short).
any idea what's wrong here?

I added back the send connector on the 2010 exchange. everything still works fine since I still have the send connector on the 2003. However...
I connected through telnet to server2 (the exchange 2010) and was able to mail internally. however I couldn't send mail externally, it gives me a "cannot relay" error when I enter my rcpt to:... command.
I am guessing that this may be the reason why the queue is not emptying itself through that send connector.
Anything else I could try to test my "send connector" on the 2010 exchange?
