Free/busy sharing using Exchange federation

We run Exchange 2010 and one of our business partners is running in Office 365. We would like to share free busy across our two organizations. Is it setup feasible,
1. We setup a federation trust with the MFG.
2. We setup an org relationship with them, they setup a org relationship with us with appropriate free busy parameters.
Most of the documentation I see is about a hybrid setup for the SAME organization. Here we are two completely separate organizations. Any documentation/links to real-world implementation would be much appreciated.

Here are some references that may be helpful to you:

  • Free/Busy not working Exchange 2007 and 2013 co-existence

    Hi,
    I'm migrating our Exchange 2007 environment to Exchange 2013. Now I am in a co-existence environment where all the mailboxes except some test-users resides on Exchange 2007. Between Users on the same Exchange MBX Server athe FREE/BUSY Information sharing
    works correctly, but between Exchange 2007 and 2013 it's not working.
    I verified my settings and also the EWS virtual directory on 2007 CAS Servers using Get-WebServicesVirtualDirectory.
    The internal and the external URLs are set to https://legacy.mydomain.com/....
    What am I missing?
    Thanks & Kind Regards,
    Jürgen

    Hi,
    According to your description, I understand that the free/busy information between Exchange 2007 and Exchange 2013 is not available for your coexistence environment. To narrow down the issue, please check the following points:
    1. Does the issue happen to all users or specific users?
    2. Although a user on Exchange 2013 can't get free/busy information from a user on Exchange 2007, please confirm whether Exchange 2007 user can get free/busy information from Exchange 2013 users.
    3. Close Outlook and only access user mailbox from OWA to check whether the issue persists. For Outlook client,
    create a new Outlook profile
    to have a try.
    4. Please make sure the virtual directories settings are configured correctly in both Exchange 2013 and Exchange 2007.
    Virtual directories settings in Exchange 2007:

    5. Restart IIS service in Exchange server by running iisreset /noforce from a command prompt window.
    If possible, please run Test E-mail AutoConfiguration in Outlook to check whether the autodiscover service can get correct Availability service URL in the results. If there is any event logs, please collect some for further analysis.

  • No Free/Busy Information for Exchange 2010 users in Outlook 2010 client, 2010 OWA shows this information fine

    I have looked for hours and hours on Google and this web site for this type of issue and nothing seems to help.
    Problem:
    On my new Windows 2008 R2 /Exchange 2010 server with IIS7 installed, I can use Outlook 2010 client to login and send and receive e-mail but when I try to busy search internal Exchange users I get no information (cross-hatch), but the sender of the Meeting Request
    can see their own free/busy information fine.  And OWA users can see free/busy information fine, as can Outlook 2003 client users against this Exchange 2010 server when logged in.
    I don't know if I have a certificate problem with regard to IIS7 or Exchange 2010, I did not create my own certificate , it is just what was installed by default when I installed and configured Win2K8 server, IIS7 and Exchange.
    On the Windows 7 workstations with Outlook 2010 client, I am not logging into the Exchange 2010 server DNS domain, if that makes any difference.  On these workstations I can ping "autodiscover.my.exchange.server.com" and my.exchange.server.com
    with no problem.  I even used this Microsoft KB to install a new _autodiscover dns entry, but it did not help :
    When I turn on logging on my Outlook 2010 client, I see this in my C:\Users\Administrator\AppData\Local\Temp\1\outlook logging\20131208-135658864-fb.log :

    Hi,
    How many users encounter this issue, all users with Outlook 2010 or some specific users?
    According to your post, the Error code 600 indicates that your Autodiscover service is working well. as for the certificate mismatch issue, we can also following the KB below to resolve it:
    http://support.microsoft.com/kb/940726/en-us
    The Free/Busy information in Exchange 2010 is using the Availability service to
    retrieve it. Please directly access
    https://mail.mydomain.ae/EWS/Exchange.asmx in IE and see whether a proper XML file is returned.
     Or we can go to
    https://testexchangeconnectivity.com and check MS Exchange Web Services Connectivity Tests.

  • Free/Busy Error from Exchange Online Cloud Mailbox to on-premise

    Hi, have a successful federation configured between Exchange 2010 SP3 (latest Roll up) and Office 365. This is to allow free/busy lookups during various migration stages (this is not Exchange Hybrid). Autodiscover works well and all functions work ok.
    On-premise users can see cloud users free/busy
    Cloud users cannot see on-premise users free/busy.
    All local based free/busy works on-premise and in the cloud.
    The Exchange Connectivity tool returns the below error from all accounts, this is the only error:
    (A wildcard certificate is in use and am wondering if this could be contributing to the problem as I have seen this once before)
    Attempting to send an Autodiscover POST request to potential Autodiscover URLs.

    Yep, indeed it does, except the password works when carrying out an autodiscover test, when testing free/busy that error appears. Lookups for free/busy work from on-premise to cloud, cloud to on-premise does not work unless you explicitly allow permissions
    on a user basis. The on-premise Exchange 2010 SP3 environment is using an external wildcard cert and thought this could be causing the issue, may consider updating to SAN based. What do you think?

  • GAL and Free Busy Information during Exchange 2007 and 2013 coexistence

    Hello Everyone,
    I am finishing up an Exchange 2013 migration from 2007.  I am currently still in coexistence and had some questions around the Global Address List and Free Busy Information.
    How to I tell if my clients are pulling address book information from my Exchange 2013 or 2007 Global Address List?  I don't want to remove the 2007 system if the clients are pulling from it.  All mailboxes are moved to Exchange 2013.
    How do I make sure my clients are pulling the Fee Busy Information from Exchange 2013 or 2007?  If I remove my 2007 servers will my clients lose Free Busy Information?
    How do I tell what Exchange version my clients are getting this information from?
    Thanks for any assistance!
    Ian...

    Hello,
    Free/busy information are retrieved from user’s mailbox by EWS service.
    GAL(I think you may refer to OAB), we can use the following command to get it’s generated server:
    Get-OfflineAddressBook |FL

  • Lync 2013 / Skype for Business sharing photos with federated contacts

    In the new SfB client I can see photos of federated contacts. I'm on Office 365 and this only happens for Federated contacts also hosted on Office 365 where we have an Exchange organisation relationship. I'm not sure if this
    is because of the new client, updated server software in Office 365 or something I just missed before.
    If I look into the client debug files I can see that the photo URL for Office 365 includes the wssecurity (federated authentication) but for onprem system it's missing.
    I have customers with Lync onprem asking for sharing the high res photos with external organisations. The classic URL-sharing is not a viable solution for several reasons. So, based on these findings:
    Is the wssecurity (Web Service Security) in the EWS path something that will come to SfB server for onpremises making ot possible to enable photo sharing between organisations having federated identity configured in Exchange?

  • Exchange 2010 Free/Busy Federation with vendor's Office 365 tenant

    Here the situation,
    ORG A
    ====
    Exchange 2010 SP3 On-premise. No externally accessible CAS available/published (we are very secure and require VPN for Outlook/OWA from home/outside network)
    ORG B
    ====
    Office 365
    ASK
    ===
    ORG B is a vendor for ORG A and we would like to have federated free/busy sharing between the two organizations. I have read the steps about setting up a federation trust, configuring org relationships both ways, configuring autodiscover on our end.
    My specific questions are,
    1. Currently we don't have any externally published CAS servers. My assumption is we need atleast one (and probably more for fault tolerance) for federated free/busy sharing correct? We obviously don't want to place this in the DMZ/externally...so what are
    the recommended configuration? Publish the CAS externally? Any other more secure recommendations? We don't have TMG or any other Microsoft solution for that purpose...are there any other options? We use Cisco IronPorts for inbound/outbound email.
    2. Does this coexistence server have to be Exchange 2013 or will Exchange 2010 sp3 suffice?
    3. Are there any other methods of accomplishing this ask? We don't want users to have to individually share calendars...so internet calendar sharing is out of the question.

    Hi,
    If the organization receives or sends Internet e-mail for the domain, we need to
    configure an
    internet facing CAS server.

  • Sharing free busy and GAL between exchange organization.

    HI, we are looking to share free busy and GAL between 2 exchange organizations. Thus far using the Microsoft federation gateway appears to be the better option for us to achieve this. Although due to both exchange organizations using the same SMTP email
    domain we may run into issues trying when both organizations attempt to create the federation trust using the same autodiscover.abcdomain.com
    What is the recommended approach to work around this issue?

    Change the e-mail domain in one of the organizations.

  • Free Busy takes over 30 seconds to retrieve on Outlook 2010 using Exchange Server 2010

    We have a small 100 user domain running Exchange server 2010 and outlook 2010 clients.  The issue is that Retrieving Free/Busy takes over 30 seconds.  
    So someone is trying to schedule a meeting has to wait Minutes see the Free/busy time for many users..  I have checked and all the users in question have published at least one month free busy time.
    It seems it would be much faster.  Anyone have this same experience and know of a way to speed it up?
    thanks in Advance
    David 

    Hi David,
    Does the issue happen in OWA? In Exchange 2010, the free/busy information is retreved by using Availability service (EWS url). Generally, if a user wants to view free/busy information when create a meeting, the http Availability service request
    would send to CAS server.
    Please check whether the usage in Exchange server is high when the slow free/busy information occurs. This reflect time would also be related to the network in your environment.

  • Exchange 2013 servers not sharing Free / Busy

    Some of the users on EXMB01 are not able to see users calendar Free / Busy information on EXMB02.
    In our exchange 2013 (CU5) environment the following server: mailbox EXMB01 and EXMB02, CAS EXCAS01, EXCAS02 and EXCAS03. Server are Windows server 2012, mail domain is mail.domain.com and does not match our internal network of local.domain.xyz
    (Non standard was setup before me).  All setting point to mail.domain.com for mail configuration.  External cert from a CA was added to all three CAS servers.
    USER1 on EXMB01
    USER2 on EXMB02
    USER3 on EXMB02
    Was able to get USER1 to see a USER3 can see all Free/Busy, subject, location now (only set the Free/Busy time) .  Added USER02 see Free / Busy, subject, location (also only set Free/Busy time). Added my own calendar to the USERS01 to the
    USERS01 outlook and can see my Free/Busy, subject, location.  I only have by default Free/Busy time set no one else added.
    What settings to I check first? Is their a PowerShell command to reset a users calendar permissions?  Is something not set correctly on the servers?

  • Exchange/Outlook 2013 No free/busy information could be retrieved

    We are getting a problem for certain users where their Free/Busy info is not visible in the Scheduling Assistant.
    HOWEVER - the same user's calendar can be viewed as a Shared Calendar without a problem.
    I believe this has been working previously and has now stopped.
    It is affecting Mac & PC user the same and is also apparent in OWA.
    Please help as typically this is affecting our VIPs.
    Thanks

    Hi,
    According to your description, I noticed that the free/busy information also couldn’t be retrieved in OWA. Please confirm your Exchange version and double check whether all users can’t use scheduling assistant to view free/busy information.
    In Outlook client, please run Test E-mail AutoConfiguration tool to test the Autodiscover service and Availability service URL:
    please open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar - Test Email AutoConfiguration. Put your email address - uncheck use guessmart and secure guessmart authentication - click Test to check your Autodiscover
    service.
    In Results tab, please get the Availability service URL. Then access it in Internet Explorer in your local machine, and check whether a proper XML file can be returned.

  • Federated free busy information - the recipients mailbox server could not be contacted

    Hi guys, really hoping someone can help with a free busy issue I'm having.  
    I've configured a new forest with exchange 2013 installed in preparation for moving all AD objects to the newly created forest to resolve a single label domain issue.  The source forest has exchange 2010 SP2 installed.  I've setup a trust between
    the forests and dns is resolving okay.  Federation has been setup for each of the forests and sharing configured but free busy info isn't available.  When trying to retrieve FB from the new exchange 2013 mailboxes i get "the recipients mailbox

  • Viewing free/busy time between gmail and exchange

    I have a need to allow users in a partner organization to see free/busy time in our calendars for scheduling. We are using Google Apps for Business. The partner organization is using Microsoft Office365. 
    If both were using O365, I know federation is possible. Is there anything similar with Gmail or any third part tools to allow both parties to see free/busy time on the others calendars? 
    This topic first appeared in the Spiceworks Community

    Hi Brian,
    I think the root cause is that the external URL was not on the E2K7 CAS servers for EWS.

    Hi,
    Please make sure that Exchange Autodiscover is set up correctly for all organizations that use an organization relationship. If Autodiscover isn't working correctly, there's no supported way for you to use organization relationships.
    Make sure that Autodiscover URLS can be resolved internally and externally for the organization with which you want to share free/busy information. 
    Make sure that the organization with which you are sharing free/busy information has its external EWS endpoint set up.
    Refer to this link for more information.
    https://support.microsoft.com/kb/2838688?wa=wsignin1.0
    In addition, if the users are in different organizations, please configure Organization relationships for them to share Free/Busy information.

    By the way, if the database are on different forest, please try to
    configure the Availability service for cross-forest topologies.
