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

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:

http://blogs.technet.com/b/meamcs/archive/2013/07/25/part-2-step-by-step-exchange-2007-to-2013-migration.aspx
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 :

Can anyone assist ? What am I missing ?
Thank You

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.

Exchange 2007 to 2013 coexistence Legacy access

I’ve successfully installed Exchange 2013 CU1 (in a cloned environment so I’m no harm done
J) and most thinks seems to work but OWA and Active Sync on EX2007 mailboxes give me some headache.
I’ve created a legacy.company.com DNS record, reconfigured the virtual directories on EX2007 and set OWA to FBA/basic.
OWA IS redirected to EX2007 legacy URL but authentication is not being passed through and you have to enter username password again at the EX2007 OWA site. Active Sync (tested on Iphone) works but you have to enter password at every sync.
What could I be missing?
/Søren Emig

Fiona,
Reading through the first technet link, it makes it seem as though redirection should happen silently and the FBA should be passed to the CAS2007 server seemlessly.
CAS2007 will consume that hidden form's data, authenticate the user and:
Retrieve and render the user's mailbox data from the Exchange 2007 mailbox server and provide the data view back to the user. The response will contain an FBA cookie for the legacy namespace, and from that point on all user activity within the session
will go to legacy CAS only.
Or proxy the request to the Exchange 2003 mailbox server and provide the data view back to the user. The response will contain an FBA cookie for the legacy namespace, and from that point on all user activity within the session will go to legacy CAS
only.
That sounds like the OWA page should render without the user logging in a second time. Also, if you look at the docs for Exchange 2010, the scenario is the same. http://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx
CAS-01 will look for an Exchange 2007 ExternalURL property
that has an ExternalAuthenticationMethods setting
that's identical to theInternalAuthenticationMethods setting
on the Exchange 2010 Client Access server. If the settings match, CAS-01 will redirect to this external URL. If source and target CAS have Forms Based Authentication (FBA) enabled, the source CAS issues a hidden form back to the browser that contains the user’s
credentials and FBA settings, along with the redirect URL. This is transparent to the user.
Now if the SSO code for Exchange 2013 is not ready, that is another matter. But there is no documentation that I could find explicitly stating this.

Exchange 2007 and exchange 2010 Federation

Hi all I am trying to federate between Three organisations
org A exchange 2007 with exchange 2010 cas
org B exchange 2010.
org C exchange 2010.
I cannot share my calendar from org A to Org B
I can share Org B to Org A and Org B to Org C.
when I try from Org A to Org B or Org C
When I try to share free/busy fro the exchange 2007 with exchange 2010 cas. The user gets an error
"calendar sharing is not available with the following entries because of permission settings on your network."
-availabilityaddressspace. Autodiscover works TXT works. I have added a user from Org B as a contact in exchange.
The exchange 2010 server is not the CAS server for the exchange environment and I is not a proxy for exchange 2007. Is this where I am failing ?
Heeeelp

Hi Nigel,
How is the impact, just one user or all users, Outlook or OWA?
If just one user, it seems like an issue on the Outlook Client side.
Please trying to re-create new profile to fresh the caches.
Please runing Outlook under safe mode to avoid some AVs, add-ins and firewall.
Found a similar thread for your reference:

Legacy Namespace for Exchange 2007 to 2013 co-existence

We are migrating from Exchange 2007 to 2013, during the co-existence phase, where is the legacy.{domain.com} namespace used? We are at the point now that we want to move all services over to the Exchange 2013 CAS servers, however... GPO settings
are used to point outlook clients to mail.{domain.com} for Outlook Anywhere. If DNS is updated to point mail.{domain.com} to the Exchange 2013 servers, will there be an issue with connectivity for people still on the Exchange 2007 servers? Do these people
need to point to legacy.{Domain.com} or will mail.{domain.com} proxy the connection to the legacy namespace? I would like to know if the GPO settings will interfer with the settings that Autodiscovery provide back.
I have read a bunch or articles on the approach, but I am still fuzzy on where legacy.{domain.com} comes into play.
Thanks in advance for your help.

In coexistence with exchange 2013 and legacy version the request happens in 2 types.
For Exchange 2010 –
Exchange 2013 does a Proxy for owa and ews requests for users in exchange 2010.
For Exchange 2007 –
Exchange 2013 does redirection for owa and ews requests for users in Exchange 2007.
Certificates:
All the required SAN entries for UM,webservices and activesync should be created.
Add external owa legacy URL to the public certificate and install it on both Exchange 2007 and
Exchange 2013 only then owa redirection will work.
You need to Include internal Legacy. Domain.com on Exchange 2007 Certificate for OWA co-
Existence.
Following change needs to be done in Firewall
External OWA URL should be directed to exchange 2013 Internet Facing CAS.
External EWS URL should be directed to exchange 2013 Internet Facing CAS.
External Autodiscover URL should should be directed to Exchange 2013 CAS.
External ActivesyncVirtualDirectory should be directed to Exchange 2013 CAS.
External UMvirtualDirectory should be directed to Exchange 2013 CAS.
Create new NAT rule on firewall for Legacy.domain.com to Exchange 2007 CAS. You can do this as well.By doing this users will be able to log on directly using the URL https://legacy.domain.com/owa with
a mailbox on Exchange 2007.
External and Internal DNS settings
Public DNS - Map all of your external public DNS records (ews,owa,activesync etc.,) to your
exchange 2013 public IP if you have dedicated one for 2013 or FQDN of your internet facing CAS server.
Example:
Current external owa URL (contoso.domain.com) – point it to dedicated exchange 2013 public ip or internet facing exchange 2013 CAS FQDN.
Current External Autodiscover – point it to dedicated exchange 2013 public ip or internet
facing exchange 2013 CAS FQDN
Internal DNS – Configure the Exchange 2007 to point SCP AutoDiscoverURI to Exchange 2013 Client
Access FQDN by changing DNS entry for Autodiscover.domain.com to exchange 2013 CAS sever Ip
address
The internal DNS records should point to the internal host name and IP address of your Exchange
2013 Client Access server
Make sure that legacy.contoso.com resolves to CAS2007 in internal and external DNS.
Authentication Settings:
This part is little bit tricky. You need to plan according to your organization. If you have FBA configured in TMG or ISA server then you need to configure accordingly.
Set the owa virtual directory authentication only to Basic in exchange 2007.
In exchange 2013 set owa virtual directory to only (Windows Authentication) or only (form-based authentication) or only (Basic, No redirection, SSL Enabled) depends according to your setup.
Things to check:
If you have redirection configured in IIS on the Exchange 2007 Server Make sure that the above
Virtual Directories doesn’t have it configured.
If you have FBA enabled on ISA or TMG then disable FBA on Exchange 2013 CAS else users will be prompted twice for authentication

Exchange 2003, Outlook 2007 and Free/Busy options

We are using Exchange 2003 and Outlook 2007 our Free/Busy options are not showing up, is the a copatibility issue between the two?

Hi,
It is by design that there is no Free/busy option for Exchange 2003 mailbox. Here is a similar thread for your issue:

Free/busy information in 2007/2013 coexisitance

I'm in the process of migrating from a single server 2007 exchange environment to a multi server 2013 environment. I'm at the point where I want to move a small group of users to the 2013 serves to do some testing. The only issue holding that back
is anyone on the 2007 server cannot view free/busy information of a user on the 2013 servers. This does work when a 2013 tries to lookup a 2007 users free/busy information.
Anyone have any idea why that would be?

Hi,
Please check your Exchange 2007 Web service in CAS configurations. We need to set it with legacy.contoso.com. Just like:
Set-WebServicesVirtualDirectory –Identity “Exch07\EWS (Default Web Site)” -InternalUrl https://legacy.contoso.com/ews/exchange.asmx –ExternalUrl
https://legacy.contoso.com/EWS/Exchange.asmx

Free/busy information unavailable in Outlook 2013 on Windows 8.1 on Exchange 2010

Hi,
This has been discussed a lot inf forums but unfortunately having followed all the guides I have found, I can't resolve it. I am the only user with the issue.
I have primarily followed https://social.technet.microsoft.com/Forums/office/en-US/ee9e1b89-bea1-48aa-9008-cae205c5e816/forum-faq-why-cant-i-retrieve-freebusy-information?forum=outlook
including recreating my profile, installing http://support.microsoft.com/kb/2850061/en-us via
Ofifce 2013 SP1, verifiying the funtion works through OWA etc etc.
I have the full version of Office 2013 Pro not the Click to Run version. It seems to be the Outlook client itself not the Exchange server. I am at a loss what to do next... please help! :)

Hi,
Please also enable Automatic Replies in Outlook, check if this feature works well.
Since the issue only occurs to one client and it works on OWA, I suggest you try these steps below to troubleshoot the issue:
1. Start Outlook in Safe Mode. It is always a helpful method to troubleshoot Outlook client issues, when in Safe Mode, Outlook doesn't load with add-ins, we can check if this issue persists when add-ins are disabled:
Press Win + R, type "outlook.exe /safe" in the blank box, press Enter.
If there's no issue in Safe Mode that you can find free/busy information again, disable the suspicious add-ins to verify which one caused the problem.
2. Perform a clean boot. This helps determine whether the issue is related to some background programs, any 3rd-party programs will be disabled. If the issue doesn't occur in Clean Boot, then we may suspect it's related to some 3rd-party programs, the detailed
steps can be found in this link below:

Outlook 2013 with Office365 exchange Scheduling assistant not retrieving free/busy information

Hi, we are using Outlook 2013 with Office365 Exchange and when using the Scheduling assistant in Outlook users are seeing "No Information. No free/busy information could be retrieved". The scheduling assistant works fine in OWA.
I have spent time trying to find an answer on the web but most answers involve different exchange variations.

Hi,
Since the problem only exists on Outlook Client, we can try running Outlook with the switch "/cleanfreebusy", this will clear and regenerate free/busy information:
outlook.exe /cleanfreebusyin the blank box, then press Enter.
You can also switch between Online and Cached Mode to check if there's a difference.

Any idea?
Thanks,

OK.
Please follow this step.
1. As you said you are in coexistence step , so for now all endpoint already point to Exchange 2010 right?
2. Check legacy owa redirect that you already configure
3. In Exchange 2010 , Make sure that you already configure "Autodiscoverinternaluri" by this command set-clientaccessserver -identity "servername" -autodiscoverinternaluri
https://autodiscover.domain.com/autodiscover/autodiscover.xml. and don't forget to create autodiscover record in DNS
4. in Exchange 2010 , Make sure that you already configure "EWS" path by this command set-webservicesvertualdirectory -identity "XXX\Default web site name" -internalurl
https://yourinternalurl/EWS/Exchange.asmx -externalurl https://yourexternalurl/EWS/Exchange.asmx
5. don't forget to replicate freebusy from Exchange 2003 to Excahnge 2010 via public folder.
You error look like client cannot get autodiscover process please check it again.

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.

[Forum FAQ] Why can't I retrieve Free/Busy information

Free/Busy information is a feature of Microsoft Outlook that allows you to see when others are free or busy so that you can efficiently schedule meetings. You can use Microsoft Outlook to publish Free/Busy information to any server
your and your coworkers have read/write access to. However, in some cases you’ll notice that you can’t retrieve Free/Busy information correctly from Outlook. You can try the below methods to troubleshoot and get the Free/Busy information again.
Since most users who often use this feature are using Exchange, all the information in this content is only based on Exchange.
General troubleshooting methods:
Method 1: Start Outlook using the ‘/cleanfreebusy’ command line switch
Method 2: Logon OWA to see if the Free/Busy information shows correctly
Method 3: Check the user’s Permission Level when only one user’s Free/Busy information can’t be displayed
Other causes
Autodiscover has not been setup correctly
Updates
Here are the detailed steps and explanation of each method and cause.
Method 1: Start Outlook using the ‘/cleanfreebusy’ command line switch
With the ‘/cleanfreebusy’ switch, it will clear and regenerate free/busy information when Outlook starts, sometimes this process fixes the problem that Free/Busy information doesn’t display correctly, and this is always the first thing we should try when
we can’t get the Free/Busy information from Outlook.
This switch can only be used when you are able to connect to your Microsoft Exchange server.
To start Outlook using the switch, we can press Win Key +
R to start Run, type ‘outlook.exe /cleanfreebusy’ in the blank box, then press
Enter.
Please note since Outlook 2013 only uses the availability service which is connected to Autodiscover, the command line switch ‘/cleanfreebusy’ has been removed as well as the associated code so that Outlook 2013 will not recognize this
command.
Method 2: Logon OWA to see if the Free/Busy information shows correctly
If you are using Cached Exchange Mode in Outlook and having trouble getting the Free/Busy information, please logon OWA, or switch to Online Mode to see if the Free/Busy information shows correctly.
If the Free/Busy information shows correctly on OWA or in Online Mode, this problem may be caused by the Outlook Data File(.ost) corruption, which leads to the sync failure. Therefore we should exist Outlook, browse to the Data File and rename it to “.old”.
The next time Outlook starts, it will regenerate a Data File to sync and we can check if the Free/Busy information can be retrieved.
The location of the Data File can be found from File tab ->
Account Settings -> Account Settings ->
Data Files tab. (Outlook 2010 and Outlook 2013)
Or Tools menu -> Options ->
Mail Setup tab -> E-mail Account -> Account Settings window ->
Data Files tab. (Outlook 2007)
If on OWA it displays fine but doesn’t show the information correctly in neither Cached Exchange Mode nor Online Mode, it may be caused by the firewall or anti-virus settings, disable them to verify if they caused the problem.
Method 3: Check the user’s Permission Level when only one user’s Free/Busy information can’t be displayed
When a user has set his Calendar Permission to None, other people will not be able to see his Free/Busy information. When we notice that we can get most people’s Free/Busy information but fail to get one specific person’s, please consider
to check his Calendar Permission:
In that user’s Outlook, right click on his default Calendar, click Properties, select
Permissions tab.
We need to at least switch the Permission to Free/Busy time to get his Free/Busy information correctly.
Other cause 1: Autodiscover has not been setup correctly
From Outlook 2007, Outlook uses Autodiscover to get the Free/Busy information. Once Autodiscover has not been configured properly, the Free/Busy information may not display correctly. If you are also seeing issues with Out of Office assistant, we may assume
that you haven’t correctly setup Autodiscover, since these two symptoms are common when Autodiscover is not configured correctly.
To verify that, please test Outlook Autodiscover Connectivity:

We can also learn Configure Exchange Services for the Autodiscover Service from:
http://technet.microsoft.com/en-us/library/bb201695.aspx
Since Autodiscover Service is more Exchange related, we need to seek Exchange support and post the question in Exchange forum:
http://social.technet.microsoft.com/Forums/exchange/en-US/home?category=exchangeserver
Other cause 2: Updates
Although Updates from Microsoft do no harm to the system for most of the time, the updates sometimes can mess things up.
Outlook 2013 November 2013 security update once became the culprit that caused some users not able to retrieve Free/Busy information from calendar scheduling. This occurs because Autodiscover fails for Exchange 2007 configurations. So in fact, this also
refers to the previous reason, Autodiscover is corrupted.
The fix for the issue above has been released:
http://support.microsoft.com/kb/2850061/en-us
Once you have some issues after updating and doubt it’s an update issue, you can always come to our forum to ask if there’s a recent update which causes the problem, we will be happy to support you. If a fix hasn’t been released yet, we suggest you uninstall
the suspicious ones from Control Panel -> Programs and Features ->
View installed updates to verify which caused the problem, also as a workaround.
Summary
The reason that we can’t get the correct Free/Busy information can vary. If you find it doesn’t work even after several general troubleshooting steps, please consider it’s Autodiscover related. For anyone who comes up against the issue that Free/Busy information
can’t be retrieved, please feel free to visit Outlook IT Pro Discussions from the URL:

Outlook 2010 Scheduling Assistent - No free busy information can be received.

Folks:
I have recently upgraded to Outlook 2010 running on Windows 7 x64. My email is exchange based. My machine is not a member of the domain my exchange server is in.
I access it my a stored credential.
Everything is fine except for Scheduling assistant. All the folks invited to a meeting (except for myself) show up as "No Information Available".
I have found plenty of posts that suggest this is also a Outlook 2007 issue, and that creating a key HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Calendar\UseLegacyFB
(value 1) solves the issue. (Example:http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/c765605d-27a7-4784-993c-925394e2e09f) I did create the key on my Outlook 2010 machine - but in HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\Calendar
key. It is not resolving my issue.
Does anyone know the Outlook 2010 solution to this issue? Note: I have Administrative privilege on my Client - but no privilege on the server. I need to get
Outlook 2010 to interface with Exchange 2007.

Hi John,
Thank you for using Outlook IT Pro Discussions forum.
From your description, I understand that you are using Outlook 2010 and Exchange account.
There is no free busy information when using scheduling assistant. If there is any misunderstanding, please feel free to let me know.
First, you must be using an Exchange server and everyone must publish their free/busy information.
Check from File > Options > Calendar Options > Free/Busy Options.
Make sure the month value for publishing is not zero.
Also, I found a similar thread here:
http://social.technet.microsoft.com/Forums/en-GB/exchangesvradmin/thread/5991f3b6-f0cc-432f-82c6-f24da0a42862
You can also try the suggestions in that thread to recreate the web services virtual directory
===============
1. Remove-WebServicesVirtualDirectory -identity "Servername\EWS (Default Web Site)" -identity "Servername\EWS (Default Web Site)"
2. IISReset –noforce
3. New-WebServicesVirtualDirectory
4. IISReset –noforce
If this problem persists, it might be related to some settings on the Exchange server side. You can also post this thread in Exchange server forum:
http://social.technet.microsoft.com/Forums/en-GB/exchangesvradmin/threads
Please take your time to try the suggestions and let me know the results at your earliest convenience. If anything is unclear or if there is anything I can do for
you, please feel free to let me know.
Best Regards,
Sally Tang
