"Your Out of Office settings cannot be displayed" when ASP.NET Role Manager is enabled on Exchange Server 2007 or Exchange Server 2010


Microsoft Office Outlook 2007 users with mailboxes homed an Exchange Server 2007 or Exchange Server 2010 Mailbox server running on Windows Server 2008 are unable to use the Out of Office Assistant. The following error message occurs in Outlook:

Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.

Users running Outlook 2003 or earlier versions, or Outlook Web Access (OWA), are able to configure and use the Out of Office Assistant features. Outlook 2007 users do not experience any other issues.

Also, Outlook Anywhere may fail to connect.

Role Management for ASP.NET has been enabled on the Mailbox server. Exchange Server 2007 and Exchange Server 2010 do not support enabling roles for ASP.NET.


Using Windows Explorer, navigate to the inetpub\wwwroot folder. In the web.config file, open the file with Notepad and look for the a section that contains the following information:

<?xml version="1.0" encoding="UTF-8"?><configuration>  <system.web>  <roleManager enabled="true" />  </system.web></configuration>
NOTE: It is possible that roleManager may have been enabled elsewhere in the system, instead of or in addition to the above. It may be necessary to check the web.config files for the EWS virtual directory, aspnet, or search the machine.config file for the section above to see if roleManager has been enabled..  

If this information is present, back up the existing file by creating a copy with a different name.  Then use the steps below:  
  1. After backing up the file, while viewing the file with Notepad, change the line containing <roleManager enabled="true" /> to:

    <roleManager enabled="false" />
  2. Exit and save the changes to the file.
  3. Click Start, click Run and type services.msc, then click OK.
  4. Right click and click Restart for the IIS Admin service.
