Integrating Exchange 2013 & Lync Server 2013: can't use a certificate with Seth-AuthConfig

I'm trying to integrate Exchange and Lyn Server. One of the first steps is to bind a correct certificate to IIS on all of the CAS servers and set it as a main certificate in the global AuthConfig object. The certificate must be the same on all of the
CAS servers because the autodiscover.domain.local DNS record points to all of them, and Lync Server uses this FQDN to access Exchange servers. The thumbprint of this certificate must be specified in Set-AuthConfig command run on an Exchange server.
We have an internal enterprise CA. I generated a certificate on one of the CAS servers and bound it to all of the Exchange services. Then I exported it, imported it on the second CAS server and bound it to all of the services as well. Now Exchange correctly uses
it for OWA, for example, and IE gives no security warnings when I connect to OWA.
However, whenever I run Set-AuthConfig command on any server, it keeps telling me that
The certificate with thumbprint XXXX was found but is not valid for use with Exchange Server (reason: PrivateKeyNotAccessible).
The key IS accessible - I can export the certificate along with its private key. What's wrong?

Here's the answer.
It seems that the -Server switch in the Set-AuthConfig command is only used to specify where you want to look for the certificate with the given thumbprint. However, it's impossible to predict which Exchange server will actually perform the operation
(the Server switch doesn't influence it a bit). It could be ANY server, even a mailbox one with no CAS role at all. And, of course, another Exchange server has no access to the certificate store of the CAS server where the certificate is actually stored. It
was exactly the case in my environment.
So in order to enable this certificate you must import it on ALL of your Exchange servers. You need't (and even shouldn't) enable it for any services on your mailbox servers if you don't want to, just import it.

  • Deploy Exchange 2013 , Lync server 2013 and shrepoint server 2013

    Hi dears ,
    I have a deployment requirement in which I have to plan for deploy Exchange 2013 , Lync server 2013 and SharePoint server 2013 on premise for 500 user and for one organization , now I have been asked to provide the software and hardware requirement
    for this deployment .
    so I wonder , is there any guide or link to find the hardware and software requirements for this deployment ?

    Hi,
    You can refer to the link below about the hardware/system requirements for Lync Server 2013:
    https://technet.microsoft.com/en-us/library/gg398438.aspx
    Note: it is not supported to install Lync Server in the same computer with DC, Exchange Server and SharePoint Server.
    If you want to deploy Lync Server, you’d better read the guide firstly before deploy it:
    https://technet.microsoft.com/en-us/library/gg398616.aspx
    For the deployment of Exchange 2013 and SharePoint 2013, you can also post case on Exchange and SharePoint forum, and there are more experts will help you:

  • Configuring Lync Server 2013 to be a partner Application for Exchange 2013

    Hello Guys,
    I just want to share my experience while configuring Lync server 2013 to be a partner Application for exchange 2013 sever. 
    As mentioned on technet you need to run Configure-EnterprisePartnerApplication.ps1 script that ships with Exchange 2013. 
    But when I tried to run the script as described on the technet article, I found it always fails with " the accepted domain is not valid"
    I have checked my accepted domains many times and i found that there's no issues with my configured accepted domain. 
    So I started to review the script to find the issue and I found that the script was configured  as below 
    $acceptedDomains = Get-AcceptedDomain ;
      if ($acceptedDomains -eq $null)
        WriteError ("There is no accepted domain so user can not be created.")
      $acceptedDomain = $acceptedDomains[0].Name;
      if($UseDomainController -eq $true)
        $user = New-MailUser -Name $username -DomainController $DomainController -ExternalEmailAddress $username@$acceptedDomain;
    set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true -DomainController $DomainController
      else
        $user = New-MailUser -Name $username -ExternalEmailAddress $username@$acceptedDomain;
    set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true; 
    which is totally wrong as below: 
    firstly it makes $AcceptedDomain variable to equal the Name of the accepted domain. 
    Not all customers configure the name of the Accepted Domain to be the Domain Name.
    Secondly  it makes $AcceptedDomain variable to equal the name of the first Accepted Domain.
    The first domain may be not the default Accepted Domain. 
    So I have configured the script as below
    $acceptedDomains = Get-AcceptedDomain | ? {$_.Default -eq "True"}  ;
      if ($acceptedDomains -eq $null)
        WriteError ("There is no accepted domain so user can not be created.")
      $acceptedDomain = $acceptedDomains.DomainName;
      if($UseDomainController -eq $true)
        $user = New-MailUser -Name $username -DomainController $DomainController -ExternalEmailAddress $username@$acceptedDomain;
    set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true -DomainController $DomainController
      else
        $user = New-MailUser -Name $username -ExternalEmailAddress $username@$acceptedDomain;
    set-mailuser -Identity $user.Identity -HiddenFromAddressListsEnabled $true; 
    I hope This help. 
    Thanks

  • How can I connect the phone network to LYNC Server 2013?

    Greetings,
    We have a working implementation of Lync Server 2013 (pc to pc), our objective is to connect lync to our phone central, receive and send calls from lync clients (pc, phone, etc), basically enterprise voice services.
    I would like to know the following:
    Hardware that I need for this beside the server.
    Extra configurations that must be done.
    If you could recommend me the hardware needed it would be helpful.

    You'll need a gateway typically. You can find a list of qualified IP gateways here: http://technet.microsoft.com/en-us/office/dn788945.aspx
    I typically lean towards the AudioCodes Mediant line, though many here love Sonus as well.  You'll need to pick a method to connect to your PBX before you begin, such as via a T1/E1 trunk, FXO ports, or a SIP trunk depending on what your PBX will
    support. 
    You'll need to configure the PBX to route calls through the T1 towards Lync and vice versa.  You'll also need to configure the gateway itself, so I'd go with a consultancy with experience here or purchase remote implementation support from the hardware
    manufacturer.
    On the Lync side, you'll need to configure dial plans, voice policies, usages, and routes:

  • Lync Server 2013 : Export-CsArchivingData Can i get the files or name of files transferred between 2 users

    I am using LyncServer 2013 And my Question is :-
    Export-CsArchivingData -
    By using this Command-let Can i get  the files or name of files transferred between 2 users 
    Whether it is stored in "LcsLog" database ?
    If not weather Lync server saves the files (which users are sending to another users ) anywhere on file system, or not ?

    Doug Deitterick has a great blog posting that should answer your question: http://blogs.technet.com/b/dodeitte/archive/2013/04/24/archiving-options-in-lync-server-2013.aspx
    The actual File is not archived in Lync, but the file name is and will be have either _p2P or _conf at the end of the name to indicate how it was transferred.
    Please mark posts as answers/helpful if it answers your question.

    The Pin authentification is enable

  • Contact Groups in Lync Server 2013

    HI,
    I have deployed the Lync 2013 server . I can successfully login to Lync client 2013 using lync server 2013. But i wan to create a group list/group  on server side and all clients/user i will add in this list/group. After login to Lync client this group
    will show on all the user on client side. In office Communicator 2007 R2 i had created the same requirement. But in lync 2013 server i did not find this kind of option.
    Help me on this
    Thanks 

    I would recommend you combine Exchange Server and PowerShell script.
    You can put all AD users enabled for Lync Server to a Distribution Group, then add this group to a reference account. Export the contact information to other Lync users.

  • Establishing Lync Server 2013 on a Child Domain

    Hi,
    We want to establish Lync Server 2013 Enterprise Edition on a child-domain. I finished the installation. Now, if i add to users to child domain and enable from Lync Server Control Panel for test, users can be signed in. However, we use child domain for only
    domain computers. We want to keep users on parent domain, not child domain. 
    I can enable users which are on parent domain, but users can not sign in. When i look Lync troobleshooting program, i got this error: "user is not sip enabled" 
    How can i solve this problem not adding users to child domain?

    Check whether the SIP address is enabled for the user
    Get-CSUser -Identity <Alias>
    SipAddress : sip:[email protected]
    Enable-CsUser –Identity "Raji" –RegistrarPool Pool01.Lync.com –SipAddress "sip:[email protected]" –SipDomain Lync.com
    Verify the output
    Get-CsAdUser | Select-Object DisplayName, SipAddress, UserPrincipalName
    Or
    Construct a SIP address using the user’s SamAccountName and domain name
    The SamAccountName is the user’s logon name: it’s the kenmyer portion of litwareinc\kenmyer. To use the SamAccountName as the SIP address use the –SipAddressType parameter followed by the parameter value SamAccountName:
    Enable-CsUser –Identity "Ken Myer" –RegistrarPool atl-cs-001.litwareinc.com –SipAddressType SamAccountName –SipDomain litwareinc.com
    Note that you also need to include the –SipDomain parameter followed by the appropriate SIP domain. With both FirstLastName and SamAccountName you must explicitly indicate the SIP domain; Enable-CsUser won’t try to make a “best guess” at determining the domain
    name for you.
    Use the user’s email address as his or her SIP address
    This is kind of a nice option: it simply grabs the user’s email address and uses that same value for his SIP address. (That way, users have just one address to remember.) To use this option, simply include the –SipAddressType parameter followed by the parameter
    value EmailAddress:
    Enable-CsUser –Identity "Ken Myer" –RegistrarPool atl-cs-001.litwareinc.com –SipAddressType EmailAddress

  • Persistent Chat (Lync Server 2013) with Lync 2010 Group Chat

    I have successfully deployed Lync Server 2013 and both 2013 and 2010 desktop clients connect and function as expected.
    The problem is with Persistent Chat. It works perfectly with the 2013 desktop client but - whilst 2010 Group Chat connects - I receive the error message "The [LOGON_DOMAIN] is not available". No chat rooms are available and I am unable to search.
    I have been unable to locate anything on the web which discusses the problem.
    I do not know whether this makes a difference but the 2010 clients use terminals rather than dedicated workstations.
    Can anyone shed any light on what the problem may be?

    Have you created a CsPersistentChatEndpoint to allow the Group Chat client (2010) to connect to Persistent
    Chat server? Please take a look at: http://technet.microsoft.com/en-us/library/jj204901.aspx

  • Office Web Apps server / Lync server 2013

    Hi I have installed a Lync 2013 Server and Office Web Apps Server. Configured Lync topology, Office Web Apps farm and certificates.
    However when i start the services i get this error message in the log saying Office Web Apps discovery failed.
    Event ID:      41033
    Description:
    Office Web Apps Server (WAC) discovery failed, PowerPoint content is disabled.
    Attempted Office Web Apps Server discovery Url:
    Received error message: Invalid Uri syntax for WAC configuration
    The number of retries: 1,
    Cause: Office Web Apps Server may be unavailable or network connectivity may have been compromised.
    Resolution:
    Check HTTPS connectivity from this box to the Office Web Apps Server deployment using the discovery Url.
    I can access the OWAS server Url from Lync Server
    Connecting to the HTTPS discovery URL is working fine, and brings up the XML-page (after i click "show all content").
    The two servers are located on the same internal network, DNS resolves fine both ways, and no firewall rules blocks any connections between the two. Can anyone please help me figure this out?
    Only identical problem found online is here (Invalid Uri syntax for WAC configuration):
    http://blogs.technet.com/b/dodeitte/archive/2012/09/10/office-web-apps-server-amp-lync-server-2013.aspx
    He resolved the problem by assigning a new OAuthTokenIssuer certificate. This however did not fix the problem in my case.
    Regards
    Sverre A. Veel

    Hi,
    In addition, please make sure you have restarted front end and office web apps server after reissuing the certificate.
