boergi84 -> Problem with Free/Busy aka Availability Service (?) (27.Jul.2006 9:06:12 AM)

Hi guys,
  • Installed latest Exchange 2007 beta 2 in a clean new environment. One server, CAS/Mailbox/Hub. Enabled Outlook 2003 support (Public Folder is installed).
  • Connected a Vista beta 2 client with Office 2007 beta 2 to the same domain
  • Creating a meeting request in Outlook but free/busy information for attendees is not available. Error message: "Suggestions cannot be provided because free/busy data could not be retrieved."
  • Same thing with OWA works well


Any ideas?

Regards, Marco

Did you configure the AutoDiscover feature and create the appropriate DNS entry in DNS?



boergi84 -> RE: Problem with Free/Busy aka Availability Service (?) (27.Jul.2006 11:43:46 PM)

No I haven't. I've just once touched a topic about configuring DNS for autodiscover but haven't found anything anymore. And for the configuration of the autodiscover feature: I tried creating a new AutodiscoverVirtualDirectory (New-AutodiscoverVirtualDirectory -server %servername%) but it has failed. I've now tried without without parameters and it did not give me an error message back but on the other hand I don't know (yet) how to check what's configured.

Anything more then this... please let me know. I guess it will take some time to get full benefit out of MSH...

Regards,
Marco

Are these attendees E2K3 mailbox users? If yes then try to go through below steps:

1. Can a E2K3 user see the FB information of a E2K7 user.
2. Is there a public folder store in E12? You can check this using the E2k7 Exchange Management Console. If not, please go ahead and create one.
3. If there is a PF store on E2k7, check if the schedule + freebusy folder exists in the system folder of the E12 PF. To confirm, open Exchange Management Shell and enter the following:
“Get-PublicFolderStatistics –Server <servername>” (excluding quotes)
4. If you don’t see an entry that looks similar to EX:/o=<org name>/ou=Exchange Administrative Group (FYBIBOHF23SPDLT), then you don’t have a Sched+ FB folder for the E2k7 admin group and you will need to run the following command to start the hierarchy sync of PF between E2K3 and E2K7:
“Update-PublicFolderHierarchy -Server <E12ServerIdParameter>”
5. If the schedule + freebusy folder exists for the E2k7 server, then there might be a Transport issue. Test to confirm that you can send mail from an E2k7 user to a E2k3 user. If this fails, then please send me the application logs from E2k7 server.

Hi Walther, thanks for your help - I really appreciate it!

1. It's a E12 org only, no E2k3 around
2. yes
3. checked, yes there are (!). Two folders, one has two items, the other zero
4. not applicable
5. not applicable because of (1)

FUP 3: How to delete a public folder, or better said, how do I find out a GUID (need this because the two folders are called the same).

Thanks,
Marco

Hello Marco, thought I would add this post, we had the exact same issue and this was our fix. 

Our problem was with the self signed certificate issued during installation. It was not a trusted CA so it would fail trying to get the availability. I setup the autodiscover by the directions in the labs and found if you suppress the ShowCertErrors registry value when you pull up f/b info you can then install the certificate into your trusted CA and will see the free busy. Outlook 2K7 is the only product that has this problem, OWA does not rely on autodiscover and 2K3 used the sched+ system folders.

Hi Andy, thanks very much for your hint.

Sounds all logic to me but still was not able to make it running.

  1. I set 'set-outlookprovider -id exch -ssl:$false'
  2. ShowCertErrors? Where is that? On the client or the server?
  3. I could import the certificate into my local certificate store every time (vista beta 2 build 5782) but it always came up with the certificate message again. any ideas?

Regards,
Marco



adompier -> RE: Problem with Free/Busy aka Availability Service (?) (8.Aug.2006 8:53:27 PM)

The ShowCertErrors is on the client.

HKCU\Software\Microsoft\Office\12.0\Outlook

Create a Key AutoDiscover

DWORD UseSSL 0
DWORD ShowCertErrors 0

This got me past the certificate errors. It is still very slow to pull in the availablity though.

Latest also suggest not setting -ssl:$false I guess the labs were just for testing purposes. I still have mine set to false.

-Andy
I guess this is why they call it Beta

Hi,

I've got the same problem in a E2K3 SP2/E2K7 BETA2 org.

The availibily service (or free busy) is not working well for the E2K7 users :

Client          Mailbox        F/B on a MBX E2K3      F/B on a MBX E2K7

OL2K7 B2     E2K7                NO                               YES
OL2K3         E2K3                YES                               YES
OWA2K3      E2K3                 YES                              YES
OWA2K7      E2K7                 NO                               YES
OL2K3         E2K7                 YES                              YES

Like you see, I've got some problems only with the OWA2K7 or OL2K7 client.

The autodiscover working well. I've check my PF on E2K7 with msh commande : “Get-PublicFolderStatistics –Server" and I see the : EX:/o=PIServices/ou=Exchange Administrative Group (FYDIBOHF23SPDLT).

I don't know what I've to check to resolve this !

In Outlook 2k7, free/busy info is dependent on the autodiscover service workin properly. You can test the Autodiscover by holding down CTRL and clicking on the Outlook client icon in the system tray. Select 'Test Email Autoconfiguration'. In the resulting window uncheck 'Use Guessmart' and hit the Test button. Outlook will either succeed at this or fail. If it fails (which it initially did for me because it was looking for a URL it couldn't resolve), look at the log to see what Outlook is trying to use as the autodiscover URL.

In my enviroment, I had to add a zone in our internal DNS for autodiscover.domain.com and then a CNAME to the internal A record of the mail server. After this, the test of Autodiscovery worked, after some time I got a certificate message, and then free/busy info worked. =)

Refer to this article for the DNS stuff:

FYI, you can also change the URL that Autdiscover uses in the Exchange Management Shell. This is helpful if you have have a cert other than the self-signed Exchange one. Using this, you can avoid any cert name mismatch errors that occur if your cert is not the same as the machine name:

set-webservicesvirtualdirectory -id:"EWS
*" -externalURL:"https://mail.domain.com/ews/exchange.asmx" -internalURL:"https:/
/mail.domain.com/ews/exchange.asmx"



brajoh -> RE: Problem with Free/Busy aka Availability Service (?) (9.May2007 5:41:23 PM)

I have gone through all the steps mentioned.  I created 2 websites since I was using 2 different certificates (one for my public domain and one for my private) and I was getting prompted for a cert warning whenever I would open Outlook 2K7.  Seperating the websites fixed that problem, but now I am not able to use the OOA or the Availability Service.  When I test my connection, everything is successful.  Any ideas
