Exchange 2010 Autodiscover Problems, cannot connect Outlook clients using Autodiscover / Outlook Any

Not open for further replies.


We have a newly implemented exchange 2010 SP1 environment, this is co-existing with Exchange 2003 in a remote site, Exchange 2007 in three further remote sites.
2 x exch mailbox roles (DAG) (Server 2008 R2 Ent, with Exchange 2010 SP1 Ent)
2 x exch CAS / HT on NLB cluster (Server 2008 R2 Std, with Exchange 2010 SP1 std)
We currently have 4 mailboxes residing on the server during the testing phase, everything was working as expected until further tests indicated that when trying to use the scheduling assistant within outlook (both 2007 and 2010) and Out of Office Assistant. These users get the message " no free/busy information could be retrieved. Your server location could not be determined. Contact your administrator" .

Incidentally, when trying to configure a new users Outlook profile, Outlook Anywhere / Autodiscover no longer automatically configures that client, and this now has to be done manually.

The interesting thing is that when using OWA, you are able to configure Out of Office, Access the Schedule Assistant with no problems.


Make sure you can ping, it should resolve to same IP as your mail server....

Try to recreate VirtualDirectories
In the console tree, navigate to Server Configuration > Client Access . In the action pane, click Reset Client Access Virtual Directory . On the Introduction page, next to Virtual directory to be reset , click Browse . Select the virtual directory you want to reset and click Next . By default, the following Client Access virtual directories are listed:
Autodiscover (Default Web Site) ecp (Default Web Site) EWS (Default Web Site) Microsoft-Server-ActiveSync (Default Web Site) OAB (Default Web Site) owa (default Web Site) After the directory you want to reset is added to the list under Virtual directory to be reset , click Next . On the Log Location page, specify the path and file name for the log file, and click Next . The log file includes the settings that exist on the virtual directory you're about to reset. These settings may be helpful if you want to re-create a virtual directory with the same settings. By default, the log file is copied to the Documents folder on the Client Access server. On the Reset Client Access Virtual Directory page, click Reset . On the Completion page, click Finish . Restart Internet Information Services (IIS). You can restart IIS by running iisreset /noforce from a command prompt window. Then Disable Outlook anywhere, then re-enable Outlook anywhere (EMC> Server > Client Access Server) Make sure ports 80/443 are port forwarded, but i assume OWA is working?* Blackberry Certified Support Specialist * Blackberry Certified Server Administrator * Blackberry Certified Server Support Specialist * Comptia A+ * Comptia Linux + * Comptia Network + * MCITP - Enterprise Support Technician * MCITP - Enterprise Desktop Administrator 7 * MCITP - Server Administrator * MCITP - Enterprise Messaging Administrator * MCTS - 70-620 - TS: Configuring Microsoft Windows Vista Client * MCTS - 70-622 - PRO: Supporting and Troubleshooting Applications on a Windows Vista Client for Enterprise Support Technicians * MCTS - 70-685 - Windows 7 Enterprise Desktop Support Technician * MCTS - 70-686 - Windows 7 Enterprise Desktop Administration * MCTS - 70-432 - Microsoft SQL Server 2008, Implementation and Maintenance * MCTS - 70-640 - Windows Server 2008 Active Directory Configuration * MCTS - 70-642 - Windows Server 2008 Network Infrastructure Configuration * MCTS - 70-643 - Windows Server 2008 Applications Infrastructure Configuration * MCTS - 70-646 - Windows Server 2008


I assume that you have applied service pack 2 on exchange 2007 in order to redirect AutoDiscover request to exchange 2010 CAS server

Please verify the configuration on the virtual directories on both exchange 2007 CAS and exchange 2010 CAS

Default settings for Exchange-related virtual directories in Exchange Server 2010

Default settings for Exchange-related virtual directories in Exchange Server 2007

Please check with the AppPool Settings on the /EWS virtual directory, and make sure that the MSExchangeWebServices AppPool is integrated to the /EWS virtual directory, otherwise, same free/busy & OOF issue will appear

Please bypass the NLB, point outlook client to single exchange 2010 CAS server, see if the issue still occurs

Please run Test E-mail AutoConfiguration on the internal outlook client, and then check the output

Please verify if the EWS virtual directory is working by accessing the URL from the output above, you shall see a lot of XML info

HTTPS://<Exchange 2010 CAS FQDN>/EWS/Exchange.asmx

Please increase the diagnostic logging level on the availability service and OOF assistant, reproduce the issue, and then check the related event in the application log on the CAS server, and MBX server

Please run ExBPA against the exchange server for health check
