Exchange Server 2007 SP3 Meeting "Add Rooms" Resources RRS feed

  • Question

  • Exchange 2007 SP3 on Server 2003 - We have a number of meeting rooms setup and recently an issue has come up.  Users are being asked to authenticate or the error "The address list cannot be displayed.  The connection to Microsoft Exchange is unavailable ..." when booking the room from scheduling assistant.  The strange thing seems to be that this authentication request (or error) only occurs after a certain amount of hours (before that the meeting room list is populated and credentials are passed without user intervention).  The user can not authenticate (even the exchange admin) with this window but when the window is cancelled or error is accepted the users can see the meeting rooms.

    This is happening with each of our users, anyone have had similar issues or any insights on how to resolve?

  • Hi,

    Does the issue only happen when users view the room mailbox's free/busy information? Please confirm whether the issue happens in OWA. 

    Please run the following cmdlet to check the room calendar processing configurations:

    Get-MailboxCalendarSettings room1 | fl

    Get-WebServicesVirtualDirectory | FL Identity,*url*,*auth*

    If there is any event logs in server, please collect some for further analysis.

  • Using Fiddler to look at the http/https conversations the Outlook client is making an https connection out to /ews/exchange.asmx and getting a response of HTTP/1.1 401 Unauthorized.
