Autodiscover exchange 2013 and 2007

hello,
i am in the process of setting up autodiscover properly for a coexistence environment of exchange 2007 and 2013.
currently, exchange 2007 has the active CAS server role. let's call it server1.contoso.com. Exchange 2013 is installed with the CAS and Mailbox role. let's call that server server2.contoso.com
Assuming all certificates have been installed, i assume that server2.contoso.com has to point to the autodiscover of server1.contoso.com until i have fully moved all mailboxes over to 2013 CAS, correct?
the powershell command i used to set autodiscover on server2 is as follows,
Set-ClientAccessServer -AutodiscoverServiceInternalUri https://server2.contoso.com/Autodiscover/Autodiscover.xml
it then asks for identity and i enter "server2.contoso.com".
Currently, when i type "get-clientaccess server | fl server,*uri I get the follow results,
AutoDiscoverServiceInternalUri : https://server1.contoso.com/autodiscover/autodiscover.xml
AutoDiscoverServiceInternalUri : https://server2.contoso.com/autodiscover/autodiscover.xml
Should they both be "AutoDiscoverServiceInternalUri : https://server1.contoso.com/autodiscover/autodiscover.xml" since server1 is the active CAS server?
Again, once everything has been migrate i will then change the CAS server to server2.contoso.com
Thanks!!

Apologies if I have confused everyone here.
we need 2 urls for Owa and EWS in 2007 and 2013. My this blog should help
http://msexchangeguru.com/2013/12/31/e20132007-urlsauth/
Undying: Answers are in line.
1. What I understand from the post marked as Answer is there is no need for legacy namespace for Exchange2007/Exchange2013 co-existence, meaning after the installation of Exchange 2013 in the environment there is no need to modify the virtual dirs on exchange
2007 side. Both 2013 and 2007 will be using the mail.domain.com namespace for all the services and once the virtual directories have been configured on the Exchange 2013 CAS it will redirect the request to Exchange2007 CAS for the Exchange2007 mailboxes. And
since there's no need for legacy namespace, it should also mean that there would be no need for any additional publishing rule in the reverse proxy (ISA/TMG), just modifying the current one (mail.domain.com) to point to the Exchange 2013 CAS should do the
trick. Am I correct?
Just to summarize, all the redirection from Exchange 2013 to Exchange 2007 will be done without the need of legacy namespace and without modifying any URls on the Exchange 2007 side.
PN Answer:
You need 2 urls for OWA and EWS.
legacy.domain.com and mail.domain.com
Also need
autodiscover.domain.com
Basically you need to change these urls on 2007 side to legacy.domain.com
This means you need to get this url added into the cert.
On TMG side direct all the traffic to 2013 and it will redirect to 2007.
you would need a new public host record for the legacy url.
2. If all that is indeed correct then why the Technet article still make it sound like that the legacy host name is mandatory? http://technet.microsoft.com/en-us/library/jj898582(v=exchg.150).aspx
(Step 7)
PN Answer: Yes we need legacy url

Exchange 2013 and 2007 coexistence and redirects

Hi all,
I'm settings up the coexistence but i've got a problem.
I've got 3 sites:
Site A: Exchange 2013 cas and mailbox
Site B: Exchange 2007 hub/cas and mailbox
Site C: Exchange 2007 hub/cas and mailbox
The problem is the owa and active sync redirect. I can open a mailbox located in site B where the legacy.domain.com dns record points, but i cannot open a mailbox from the exchange 2013 nor 2007 owa from site B to C.
I configured only the internal url leaving the external one blank.
How do i redirect all the requests to a mailbox located in site C from site A and B?
Thanks,
D.

You need to have External URL too, so that redirection can take place.

Outlook 2010 connecting to Exchange 2013 and 2007 ... delivery fails

Hello,
we are having a problem with a few Outlook 2010 Clients that have two Exchange accounts setup in one profile. One account is connecting to the company's Exchange 2013 Server, the second account is connecting to an external provider's Exchange 2007 infrastructure
using Outlook Anywhere.
The companies Exchange 2013 was recently migrated from Exchange 2010 and this is the point where the problem started.
Some users are no longer able to send using the external Exchange 2007 account. When they try they are receiving an NDR with the following error message:
#554 5.6.0 STOREDRV.Deliver; Corrupt message content## from the external provider's servers.
When I setup a profile containing only the external provider's mailbox everything works fine until I am adding the company's Exchange 2013 back in at which point the same error appears.
We have no problems using the company's Exchange 2013 servers.
Does anyone have an idea what causes this and how to resolve it? The external provider is uncooperative in troubleshooting so we are left with the problem.
Thank you
Sascha

Hi,
The problem should be related to the External Exchange 2007.
Please refer to this kb below:
http://support.microsoft.com/kb/2203381/en-us
This problem occurs when the email message is a multipart/mixed MIME message which contains a text/plain body and an application/applefile body. If the corresponding body is not a real application/applefile body, the Exchange Server 2007 server considers
that the email message is invalid. Therefore, it generates the NDR. However, Exchange Server 2010 can deliver this kind of email message successfully.
To resolve this problem, you should let the External Provider install the following update rollup:
2279665 Description of Update Rollup 1 for Exchange Server 2007 Service Pack 3
Hope this helps.
Thanks,
Melon Chen

Exchange 2013 and 2007 - Coexistence and ActiveSync

Good morning all,
We're currently in the process of migrating our Exchange server from 2007 to 2013, and am experiencing a few problems. At the moment, OWA redirection works fine, but ActiveSync does not. At the moment the 2013 Server isn't public facing, it's internal until
all testing is complete. However despite being on the LAN, when an iPhone is configured to target the 2013 server, it isn't proxying to the 2007 CAS, but instead provides a vague error of being Unable to Verify account information. No mail is retrieved.
Has there been a step I've missed to allow this to work seamlessly?

Generally, both the internal and external Exchange 2007 ActiveSync URL should be pointing to the legacy namespace - legacy.yourdomain.com. If you've set correctly the internal name resolution (resolving the legacy namespace to the internal Exchange 2007
IP address), ActiveSync should be working fine.
Have you tried Android phones as well?
Alternatively, you can set the Exchange 2007 ActiveSync External and Internal URL to $NULL, forcing Exchange 2013 CAS to proxy all requests to the Exchange 2007 CAS. This way devices are not affected by a redirect.

Exchange 2013 and Outlook 2007

Is there a new way to connect EX2013 to Outlook 2007 SP3?
MSB

Hi Baker,
According to the description, I notice that you want to migrate from Exchange 2010 to Exchange 2013 and want to know how to connect Exchange 2013 with Outlook Client 2007.
Following is an article about the migration, for your reference:
Upgrade from Exchange 2010 to Exchange 2013
http://technet.microsoft.com/en-us/library/jj898583(v=exchg.150).aspx
Outlook client uses Autodiscover and Outlook Anywhere to connect to Exchange server, please make sure services’ URLs configured correctly.
If you want to communicate with external users, you need to apply a certificate issued from a Public CA.
After configuring all the points above, please run “Get-Mailbox –Identity allen | FL *GUID*” in EMS to get mailbox GUID of allen’. Input the GUID into server name filed.

Introduction of New OAB Architecture in Exchange 2013 and Some General Troubleshooting methods

Exchange 2013 is different from previous versions of Exchange server on architecture, some of the old features have been changed. In this FAQ, I will demonstrate the changes on OAB and list a common issue for your reference.
[Agenda]
1. Differences between Exchange 2007/2010 OAB and Exchange 2013 OAB
a. Generation
b. Distribution
c. Download
2. Common issue and troubleshooting
3. More information
[Difference between Exchange 2007/2010 and Exchange 2013 on OAB]
As we know, OAB in Exchange 2007/2010 has 3 points, OAB files generated from MBX server, distributed to CAS server and downloaded to Outlook client. However in Exchange 2013, these 3 points have a little different from previous servers. For example, the OAB
Distribution process doesn’t depend on Microsoft Exchange File Distribution service anymore. Now let me show you the changes of OAB in Exchange 2013.
[OAB Generation]
====================
Exchange 2007/2010:
1. OAB generation server is the specific MBX server which has –server property.
2. If MBX01 is down, OAB generation will be affected.
3. Previous Server using Microsoft Exchange System Attendant service for OAB generation.
4. OAB generation is a scheduled process. By default, OAB files generated at 5:00AM every day.
5. The OAB files which generated from MBX server are located in following path:
C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\OAB\GUID folder
Exchange 2013:
1. OAB generation server is the MBX server that hosts a special type of arbitration mailbox, called organization mailbox. Thus, the same OAB files could be generated from multiple
MBX servers.
2. If one of the MBX server down, other MBX server still have the ability to generate the specific OAB files.
3. Exchange 2013 server using OABGeneratorAssistant for OAB Generation.
4. OAB generation is a throttled process. It depend on the Server workload.
5. The OAB files which generated from MBX server are located in following path:
C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\OAB\GUID folder
[OAB Distribution]
====================
Exchange 2007/2010:
Previous Servers use Microsoft Exchange File Distribution service to distribute OAB files from MBX server to CAS server. The distributed oab files stored in CAS server.
Exchange 2013:
The OAB files doesn’t distributed to CAS server. The OAB files only stored in MBX server.
[OAB Download]
====================
Exchange 2007/2010:
If Autodiscover works fine, Outlook should use OAB URL to get the OAB files and download it.
If Autodiscvoer doesn’t work, authenticated users can also get the OAB from the CAS server local disk.
Exchange 2013:
Microsoft Exchange File Distribution service has been removed from Exchange 2013 and the OAB files stored in MBX server. CAS server will proxy all OAB download requests to the appropriate MBX server.
Outlook also use Autodiscover to get the OAB URL and download it.
[Common issue and Troubleshooting]
Issue: Outlook doesn’t download OAB files automatically. When I try to manually download OAB, get this error: Task xxx reported error (0x80190194): The operation failed.
Troubleshooting:
1. First, please run following command to check the information of OAB Generation Server.
Get-Mailbox -Arbitration | where {$_.PersistedCapabilities -like “*OAB*”} | ft Name, Servername, Database
Example result as below:
2. Please make sure the authentication settings and URLs are set properly.
3. Try to verify whether the OAB files generated from MBX server successfully. Path as below:
C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\OAB\GUID folder
4. If all of the settings above set correctly, please try to check Autodiscover. Run “Test E-mail Autoconfiguration” to check whether there is anything abnormal on OAB. If has, please search the error code on MS official documents.
5. If this issue is related to local cache, please try to delete the OAB caches from local PC and re-download OAB for testing. Path as below:
C:\Users\Administrator.CU1(different)\AppData\Local\Microsoft\Outlook\Offline Address Books

Hi Techy,
According to your description, I am still not quite sure about your environment. Could you please provide more information about it, such as:
1. How many Exchange servers in your coexistence environment? One Exchange 2010 with all roles and one Exchange 2013 with all roles? Or several Exchange 2010 and multiple Exchange 2013?
2. Are there two sites in your environment? What’s the Exchange deployment in different sites?
3. Please confirm if both Exchange 2010 and Exchange 2013 are Internet-facing.
Additionally, if you are using different namespaces for different services for internal access and external accessing, we need to include all service namespaces in your certificate with IIS service. Personal suggestion, we can follow ED Crowley’s suggestion
to use split-brain DNS in your environment and only use the same namespace for Exchange service URLs.
The following article described the details about how to configure different namespace for Exchange services by using Load Balance in Exchange 2013:

Exchange 2013 - Outlook 2007 - Server name GUID

Hi Guys.
I am hoping someone can shine some light on something for me.
Right now I have the following with roles.
1 x Exchange 2010 - MBX & CAS
1x Exchange 2013 - MBX
1 x Exchange 2013 - CAS
Mix of Outlook 2007 & 2010
I migrated a user from Exchange 2010 over to Exchange 2013 and the process went fine. Email flow is working, OWA and Active Sync again working ok.
However when we opened Outlook 2007 it displayed a message to say an Administrator had made changes and we needed to restart Outlook. No issues there.
Outlook connected up fine and everything works. However when you look in the mail profile for the Exchange server name i see something like
[email protected]
Also Outlook Anywhere is ticked and when you untick it from the client and then open it again it comes back.
Are the above items of migration?

Hi,
RPC is no longer a supported direct access protocol. This means that all Outlook connectivity must take place using RPC over HTTP (also known as Outlook Anywhere).
Outlook clients no longer connect to a server FQDN as they have done in all previous versions of Exchange. Outlook uses Autodiscover to create a new connection point comprised of mailbox GUID, @ symbol, and the domain portion of the user’s primary SMTP
address.
To expand on this a little bit, I worked an issue with a new Exchange 2013 environment for 3 days before figuring out that you do NOT specify a server name where it asks for it in Outlook, you use the format mentioned above.
For reference, I received a very particular error from testconnectivity.microsoft.com that made no sense until I discovered the server name format. If a test fails with a 404 HTTP Not Found error and an X-CasErrorCode of MailboxGuidWithDomainNotFound,
this is most likely your problem. Its very frustrating that Microsoft does not have it documented anywhere exactly what this error means, would have saved me a lot of time and energy.

Create failover cluster to host Windows 2012 DC, Exchange 2013 and SQL as VMs

One of our clients has running Windows Essential 2012, SQL and exchange 2007 as VM on VMware for 4 years without major issue. However, the physical server is getting old and have some hardware issues recently. They have budgets to buy two Dell servers, EqualLogic

Exchange 2013 and Exchange 2010 coexistense

We have a and exchange 2010 organization with SP3 on most servers except for one 2010 CAS server that still requires SP1 for the purpose of legacy application compatibility. Can we introduce exchange 2013 in the org or will the setup detect
that there is an exchange 2010 server still with SP1 and fails to continue?

Hi,
For Exchange 2013 coexistence with Exchange 2010, the mininum version of Exchange server is Exchange 2010 SP3 on all Exchange 2010 servers in the organization. For more information about it, please refer to the Coexistence of Exchange 2013 and earlier versions
of Exchange server part in the article below:
http://technet.microsoft.com/en-us/library/jj898583(v=exchg.150).aspx
Personal suggestion, please upgrade your legacy application to the latest version which is supported with Exchange 2010 SP3 or higher Exchange version.

Exchange 2013 and exchange 2000

Hy guys...
I have this problem...i have a dommain controller x.com and i installed Exchange 2013 on it. I have another dommain controler
y.com with Exchange 2000. Thex.com dommain sends and receives mails from other Exchange 2013 servers but when it comes to
y.com dommaind i am only able to send emails to
[email protected] I cannot send emails from y.com
(Exchange 2000) tox.com (Exchange 2013).
Bothx.com dommain controller and y.com dommain controller are in the same network and i fave connectivity between them.
What might be the problem?
Than u,
M.S

Hi,
Firstly, it’s not supported to install Exchange 2013 and Exchange 2000 in the same organization and it’s not recommended to install Exchange server on Domain Controller.
http://technet.microsoft.com/en-us/library/ms.exch.setupreadiness.exchange2000or2003presentinorg(v=exchg.150).aspx
To understand more about the mail flow issue, I’d like to confirm your meaning that two DCs are in the same network.
If they are in the same forest, it’s by design that Exchange 2013 and Exchange 2000 cannot coexist.
For general mail flow troubleshooting , we can use telnet to check it.

Exchange 2013 and DNS Round Robin downside?

Hi guys,
I have a question regarding Exchange Server 2013 (SP1) and the use of DNS round robin.
I have a customer that currently is running 2 CAS servers with NLB and we are currently investigating if it would be appropriate to move to a DNS RR solution so we can remove the CAS servers and install the CAS role on the Mailbox servers.
(yes I know that CAS with NLB and Mbx with DAG cannot be used on the same server)
What would be the downside of DNS RR?
Request 1 will go to first MBX server, Reqeust 2 to second MBX server, Request 3 to third MBX server and then start over again. If MBX server 1 goes offline, it will still be used within the DNS RR solution and clients will be redirected towards that server.
But how will clients react? Will Outlook 2010/2013 timeout since the server is not responding and do a autodiscover lookup again and then hopefully jump on the DNS that points towards another server?
Is this true for pop/imap or a receive connector for SMTP relay aswell?

Hi Fredrik,
Hope this helps out...
Round robin doens't check the load on the network interfaces.It just passes on to the next one; for example Server1, Server2
If server1 has a lot of traffic on his nic he still get more traffic onto his nic when round robin wants to.
NLB gives some checkes on the load on the interfaces. Therefore it will make sure that that all servers has about the same amount of traffic.
In Windows NLB we can able to create port rules for the virtual ip which is not applicable when you go DNS Round Robin
DNS round robin the clients will see different IP addresses Wherea NLB uses single IP Address
DNS round robin is not a good solution for redundancy. If one of the nodes goes down, you first have to go and remove its A record from the DNS server but then it may take some time before such a change is propergated. In the meantime you may have a number
of clients attempt to access the dead IP.
With load balancing you can remove a host from the set immediately (if it doesn't detect an unresponsive host automatically). The only affect of a downed server on the clients would be if some of the clients had session
data on that server.

Exchange 2013 and 2010 co-existance

We will have 2013 and 2010 exist together for a while...we plan to move away from using Unified Access Gateway for HTTP redirection to our Exchange services and implement Kemp
load balancers...two at our HQ site and two at our DR stie...
We plan to have a one arm configuration...from what I gathered...each load balancer will have a network connection and only one network connection and be on the same network as
our new Exchange 2013 servers. Can someone take a look at my config and give some input whether or not this will work and some suggestion on Ex13 urls, cert SAN names, etc.
HQKemp 2400 A
HQKemp 2400 B
DCKemp 2400 A        DCKemp 2400 B

Virtual IP   172.16.1.106
                         Virtual IP
172.25.1.104
From the video I’ve watched for Kemp install…we’ll create the following internal DNS records for the Exchange services that will be configured on balancers.
OWA/ECP
    mail.corp.local.com
              172.16.1.107
EWS               ews.corp.local.com

ActiveSync      mobile.corp.local.co
172.16.1.110
OA                 oa.corp.local.com
172.16.1.111
Autodiscover   autodiscover.corp.local.com 172.16.1.112
Question:
We will configure the Exchange services with these ip addresses linked to each service on all four load balancers?
Or will DR site load balancers have different IPs configured for same Exchange services?
Exchange services are split between our two sites…meaning Outlook Anywhere is configured for our CAS servers at our DR site and ActiveSync comes to HQ CAS servers as an example…so
I want all Exchange services to come through the newly installed load balancers at HQ and if they don’t respond…the Exchange services get redirected to the load balancers at our DR site.
Can you give some insight on the config of load balancers as to how we can do that?
I have a question about the cert we will have.
Our Microsoft rep says we should get a new wildcard cert…currently we have a UCC cert with the following SANs attached.
Will this new cert have to be installed on load balancers?
If so…can you suggest some ideas as to what new SANs I need if any of the new cert with Exchange 2010 and 2013 co-existing for a while.
Below are the SANs on our current UCC cert.
Outside resolvable SANs
Webmail.corp.local.com
205.223.19.25           portal.corp.local.com     205.223.27.78
Portal2.corp.local.com
205.223.19.25
Autodiscover.corp.local.com
205.223.19.25
Internal SANs
Hqcas1.corp.local.com
Hqcas2.corp.local.com
Dccas1.corp.local.com
Dccas2.corp.local.com
Owamail.corp.local.com
(this CAS Array server name that HQ CAS servers create)
What do you suggest we use for the external urls on Exchange 2013 for these services?
Our firewall guy says we’ll use same names,
but I’m not sure if we try to use same name if we’ll get an error?
Active Directory may say name already in use?
We plan to have firewall to just redirect requests for external urls to load balancers…sound correct?
Meaning load balancer won’t have an external NIC defined…which makes it a one arm config…correct?

Exchange 2013, Outlook 2007 clients Problems with Outlook Anywhere connection

Hi everyone,
I have a mail system Exchange 2013 SP1, on Windows Server 2012 R2.
I have only one mail server with the Client Access and Mailbox roles Server.
I have a Wildcard certificate type *. Mydomain.com.
All connections to the Outlook Anywhere Outlook 2010, Outook 2013 work correctly.
The ActiveSync connections are working properly, too.
But Outlook 2007 clients connecting with Outlook Anywhere asking for credentials continuously fail continuously.
How can I solve this?
thank you very much

Hi,
Based on my experience, we need to set Outlook provider with the domain name if it's wildcard certificate:
Set-OutlookProvider -Identity EXPR -CertPrincipalName msstd:*.domain.com

Thus, I recommend you try the above configuration and test the Outlook connection again.
Thanks,
