Direct booking does not work when free and busy information is unavailable (305390)

SYMPTOMS

If free and busy information is unavailable and you use the Web Conferencing Scheduler to schedule a conference while you are logged on as an anonymous user, you may not receive notification that indicates whether the conferencing resource is available.

CAUSE

This issue can occur if free and busy information is unavailable. Typically, direct booking occurs when free and busy information is available and the scheduler will receive notification. When free and busy information is unavailable, the success or failure of the booking cannot be determined and the meeting is asynchronously booked. Asynchronous booking does not provide a method to notify the user whether the booking succeeded or failed.

WORKAROUND

If you cannot resolve the issue that is making the free and busy information unavailable, you can work around this issue by editing the Send.asp file and commenting out the following lines:

    If (E_WEBSCHED_RESOURCE_FREEBUSY_UNAVAIL = Result) Then
        Result = 0
    End If

MORE INFORMATION

If free and busy information is available and the resource is overbooked, you should receive the following error message:

Please try the following:
