EXCHANGE SERVER 2013 CLIENT ACCESS ROLE BASED QUESTION

In my environment,i have to install two CAS in two different host machines and mailbox server on a different host machine.can it be possible?if possible then please tell me the procedure how can these communicate with each other?and is this a cas array?please
help me,i am confused. 
trainee

Yes you can always go ahead and do this . Having 2 cas and one mailbox is not going to harm in anyways but one cas can handle  all the connections as far as you have less number of users and you can have equal number of mailbox servers as well so that
you can manage the DB's btw 2 mbx servers  by setting up DAG.
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question.That
will encourage me - and others - to take time out to help you.

  • Exchange Server 2013 Edge Transport Role

    Dear,
             I have a question regarding Exchange Server 2013 SP1 that, I have installed Edge Transport Server Role on separate box without Domain Joined. Obviously I installed Exchange CAS and Mailbox on Same box with
    Domain Joined in Corporate LAN.. But my edge is placed on DMZ and it is ready with all configuration, Mailbox Server Synchronization is also installed with Edge. Means all required configuration are properly configured and it is verified. But I want clients
    to OWA Access from Edge only. Because I want to restrict my internal network from the internet. So kindly provide me any possible ways to access OWA from Edge only ??. I have see some another methods like "Web Application Proxy instead of TMG because
    TMG is expired"..
    Kindly provide me possible ways or URL so I will configure it..
    Thanks.

    1) Disable TCPChimney and RSS on CAS and Mailbox Servers by running below commands
    netsh int tcp set global chimney=disabled
    netsh int tcp set global rss=disabled
    2) Disable unwanted Add-Ins in outlook that may open many sessions
    3) If above steps doesnt resolve, you can delete existing outlook profile and create new Outlook online profile

  • Exchange Server 2013 Database not showing in ECP after removal of Exchange Server 2010

    I recently complete the migration of my Exchange 2010 server to Exchange 2013. I then proceeded to uninstall the 2010 server using setup.com /m:uninstall. At the end of the process I received an error that it did not complete the uninstall.
    I checked the server and Exchanged 2010 was removed. When I checked ECP on 2013 it still showed the old 2010 server listed. I used ADSI edit and manually removed the old sever.
    Now when I log into 2013 ECP I only see the one serve but when I go into databases, none are listed. I check under the server itself and it shows the database that it is using but it is not listed under the database tab.
    If I do a search under the database tab I can find it and adds it to the list. I can then open and view details.
    My issue is, after I log out and then back in, I have to run the search to find the database again. In ideas on how to have it show up in the list like it did  before I removed the 2010 Exchange server?
    Thank you,

    Hi,
    From your description, I recommend you verify the following things for troubleshooting:
    1. Please make sure that AD replication is completely by checking the user object's homeMDB attribute. This value should contain the DN value of the Exchange Server 2013 mailbox database.
    2. Wait 30 minutes for the cache on the Exchange Server 2013 Client Access Server to clear or restart the MSExchangeOWAAppPool on the Exchange Server 2013 Client Access Server.
    For more information, here is a kb for your reference.
    Exchange 2013 Redirects to Exchange 2010 for OWA and ECP

  • Exchange Server 2013 and Remote Access VPN on a single server running Windows Server 2012?

    Just by way of background, I have been installing and administering network servers, e-mail systems, VPN servers, and the like for many years.  However, my involvement with Exchange and Windows Server has been mostly on the forensics and data recovery
    level, or as a (sophisticated) user.  I have never tried to deploy either from scratch before.  My deployment experiences have been mostly with Linux in recent years, and with small private or personal "servers" running such cutting edge
    software as Windows XP back when it was new.  And even NetWare once.
    When a client asked me if I could set up a server for his business, running Exchange Server (since they really want Outlook with all of its bells and whistles to work, particularly calendars) and providing VPN access for a shared file store, I figured it
    could not be too difficult given that its a small business, with only a few users, and nothing sophisticated in the way of requirements.  For reasons that don't bear explaining here, he was not willing to use a vendor hosting Exchange services or cloud
    storage.  There is no internal network behind the server; it is intended to be a stand-alone server, hanging off a static IP address on the Internet, providing the entirely mobile work-force of about 10 people with Exchange-hosted e-mail for their computers
    and phones, a secure file store, and not much else.  If Exchange didn't need it, I would not need to install Active Directory, for example.  We have no direct need for its services.
    So I did the research and it appears, more by implication than outright assertion, that I should be able to run Windows Server 2012 with Exchange Server 2013 on a server that also hosts Remote Access (VPN only) and does nothing else.  And it appears
    I ought to be able to do it without virtualizing any of it.  However, I have spent the last three or four days fighting one mysterious issue after another.  I had Remote Access VPN working and fairly stable very quickly (although it takes a very
    long time to become available after the server boots), and it has mostly remained reliable throughout although at times while installing Exchange it seems to have dropped out on me.  But I've always been able to get it back after scrounging through the
    logs to find out what is bothering it.  I have occasionally, for a few minutes at a time, had Exchange Server willing to do everything it should do (although not always everything at the same time).  At one point I even received a number of e-mails
    on my BlackBerry that had been sent to my test account on the Exchange Server, and was able to send an e-mail from my BlackBerry to an outside account.
    But then Exchange Server just stopped.  There are messages stuck in the queues, among other issues, but the Exchange Administration Center refuses now to display anything (after I enter my Administrator password, I just get a blank screen, whether on
    the server or remotely).
    So, I am trying to avoid bothering all of you any more than I have to, but let me just begin with the basic question posed in the title: Can I run Exchange Server (and therefore Active Directory and all of its components) and Remote Access (VPN only) on
    a single Windows Server 2012 server?  And if so, do I have to run virtual machines (which will require adding more memory to the server, since I did not plan for it when I purchased it)?  If it can be done, can anyone provide any pointers on what
    the pitfalls are that may be causing my problems?  I am happy to provide whatever additional information anyone might like to help figure it out.
    Thanks!

    An old thread but I ran into this issue and thought I share my solution since I ran into the same issue. Configuring VPN removes the HTTPS 443 binding on the Default Site in IIS for some strange reason; just go and editing the bindings, add HTTPS and things
    should be back to normal.

    Hi  NJv7300
    Thank you for your question.
    By your state, I know you get error when you use Get_ClientAccessServer. I think it caused by AutoDiscover, you can check it.
    You can refer to the following link:http://www.shudnow.net/?s=autodiscoverserviceinternaluri
    You can refer to the following steps:1. 
    1. Using LDP, locate the following container:
    CN=<SERVERNAME>,CN=Autodiscover,CN=Protocols,CN=<SERVERNAME>,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<ORGNAME>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<DOMAIN>,DC=<TLD>
    2. Double-click the <SERVERNAME> under Autodiscover and look for the "serviceBindingInformation" value:serviceBindingInformation (2): AutoDiscover.Corp.HMSA.com;
    https://honmail.corp.hmsa.com/autodiscover/autodiscover.xml;
    serviceClassName: ms-Exchange-AutoDiscover-Service;The proper format for the Autodiscover URI is
    https://serverfqdn/Autodiscover/Autodiscover.xml
    3. Ran Set-ClientAccessServer -Identity HON10343 -AutodiscoverServiceInternalUri
    https://honmail.corp.hmsa.com/autodiscover/autodiscover.xml
    4. Ran Get-ClientAccessServer, but received an error after HON10343 was enumerated.
    5. Next, did another Set-ClientAccessServer on HON10344.
    6. Finally, ran Get-ClientAccessServer and enumerated all CAS servers in the org without error.
    7. Tested opening EMC on both Exchange 2007 and 2010 and were able to successfully expand the Server Configuration for every role and enumerate all servers.
    If any questions, please let me know.
    Best Regard,
    Jim Xu

    Resolved ! :)
    Root Cause: The user account I was using had all the required privileges for Exchange Installation but was not having access to edit the registry of the server. Enable access to registry edit tools and you are good to go.
    As an alternate you can also try installing using Domain Administrator account if in case there is an IT Policy constraint in the former method.
    Thanks to all.

  • Installation of Client Access role fails on Windows Server 2008 R2 (Execution of: "$error.Clear(); Install-ExchangeCertificate -services "IIS, POP, IMAP")

    Hello
    I am trying to install Exchange Server 2010 beta 1 onto a Windows Server 2008 R2 (build 7000) machine which has also been set up as a domain controller.
    However when attempting to install the Client Access role, setup fails with the error below.
    Does anyone know of a way to get around this please?
    I have already searched for this error and not found any similar threads.
    Also every time I press the code button on this forum it crashes the browser and I keep losing the message! (IE8 from within Server R2). Also the message box is very small, will not expand and keeps jumping to the top.
    Thanks

    Hello
    Thanks for all the replies.
    I have since wiped the system and installed everything again and it all worked this time so not sure what was wrong last time. I did try to uninstall all Exchange components and then uninstall IIS and Application server, reboot and re-install but I received the same error still when it came to installing the client access role.
    Walter: I just attempted the standard installation which should have used the default self-signed certificate. Everything was a fresh install done at the same time on a freshly formatted PC.
    For info last time when it failed to work:
    - Installed Windows Server 2008 R2
    - Installed Domain Controller role using dcpromo. I set the forest and domain as Windows Server 2008 R2
    - Added a forest trust between main domain and test Exchange domain (set up as ex2010.local)
    - Installed IIS and Application Server role
    - Installed Hyper-v role
    - Installed Desktop Experience feature
    - Installed Exchange and recieved the error
    When it worked I set up the forest and domain in Windows Server 2008 mode (i.e. not R2), installed Exchange first and then set up the forest trust and then Hyper-v. It did say it failed to configure dns which was probably because it started trying to do automatic updates half way through the dcpromo! DNS seems to work ok though.
    I did notice this time that Hyper-v gave a warning about the virtual network adapter not being set up correctly and the local network did not work correctly although I could access the internet. Not sure if this could have been related to the cause of the problem previously. For now I have disabled the virtual network until I get time to try and get it working and so the mail will work in the meantime.
    I also noticed that Hyper-v added an extra 443 ssl binding to the default website so as it had 2 bindings on port 443 it refused to start. After deleting one it worked.
    I decided to install Exchange onto a domain controller as it is only a test and I wouldn't do it in a live environment. I am also short of test machines! It didn't give me any warnings about this actually, I think previous versions warn you that it is not recommended.
    Andreas and Chinthaka: I did not know about the requirement to run the domain at 2003 mode. The main domain is running in 2008 mode with Exchange 2007 so I assume this is just a temporary beta related requirement. It does seem to be working (second attempt) so far in a 2008 mode domain although I haven't had a chance to fully test it yet.
    Thanks

  • Exchange server 2013 - cannot send / receive external emails - we can access owa -we can send/receive internal emails

    Exchange server 2013 in Windows server 2012 VM
    It was working fine then start the issue.
    Firewall is managed externally and the last report said:
    "I checked the firewall logs, which shows traffic being allowed through port 25 from 10.10.10.10 to 4.28.237.225: Log Number 116 Last Activity 2014-08-28 23:48:33 Status [accept] Src 10.10.10.10 Dst 4.28.237.225 Service SMTP Policy ID 1 Src Port 64081
    Dst Port 25 While I showed one log, there were multiple log entries showing the same: traffic being accepted through port 25 from 10.10.10.10 to 4.28.237.225.
    Can you verify that the mail server is set up so as to allow port 25? "
    Today I was able to telnet the server from home: successfully

    Again, OWA is able to access and send/receive emails internal but never external even no bounceback  just it never arrive.
    Help me please. This is my first admin chaos...

    Hi,
    Is there any update with your issue?
    If the CAS and Mailbox servers are collocated on the same server, the SMTP Receive connection for the Transport service will listen on 2525 instead of 25. If you install the CAS and Mailbox on the same server, please make sure that port 2525 is open.

  • Writing client app to connect to Exchange Server 2013 and set OOF for users on vacation

    I am coding an C# app that should connect to Exchange Server 2013 on-premise (Servers Location is not in our Company). I`ve got an account (User and Pass) with readonly admin-rights for now and want to read and set OutOfOffice Objects for other users. I
    decide to use EWS Managed API over Autodiscovery but I am bit confuse how
    I tried to connect with "service.UseDefaultCredentials = true" and read contacts -> this code works:
    try
                ExchangeService _service
    = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
                _service.Credentials
    = new WebCredentials("service.exchange",
    "1234", "domain");
                _service.TraceEnabled
    = true;
                _service.TraceFlags
    = TraceFlags.All; _service.UseDefaultCredentials
    = true;
                _service.AutodiscoverUrl("[email protected]",
    RedirectionUrlValidationCallback);
                foreach
    (Contact contact in _service.FindItems(WellKnownFolderName.Contacts,
    new ItemView(2)))
    var test = contact;
            catch
    (Exception exception)
                Console.WriteLine(exception);
    After that I tried the same with _service.UseDefaultCredentials = false; got error -> "The Autodiscover service couldn't be located." I am not shure if this "direct log on" is the right way, On msdn I've read about "delegate access"
    and "Impersonation" (NTLM and Basic Authentication) I'am a bit confused. Can anybody help me?

    hi,
    when you set a credential, you don't have to set the UseDefaultCredentials property (it is already updated).
    For autodiscover, you should try to set the property EnableScpLookup to True if you are in the Exchange domain or it is known by the current domain.
    Autodiscover uses a domain query (through Active Directory) and/or a dns query (this requires a DNS register for autodiscover.domain.net) to determine the access to the autodiscover service URI.

    Hi allAfter a rather heated conversation with our MSP I come to you for guidance.We've recently acquired another business and need to add two new sites plus a cloud hosted server to our network. The current layout is as follows (forgive my terrible diagram):Top is our business, bottom is the one we've purchase, red indicates how the VPNs are structured. We have extensive on-premise infrastructure at the Main Office (top left) so we are planning to retire the cloud hosting once our systems have been merged but in the meantime we need to be able to access their system and vice versa so I am hoping for the following:In summaryNew link from the cloud hosting to the Main OfficeNew link from the alt-main office to Main officeNew link from the new "other site" to Main OfficeNow, our VPNs are controlled by our MSP, after a two week delay...
