CAUSE

There are several reasons why the decline e-mail notification and "Conference Not Found" Web page are displayed:

Modifying Video Conference Resources
If an administrator tries to change a video conferencing resource on a running conference to a resource that does not have the identical properties, such as Send audio on join, the change operation does not work. A decline e-mail is sent to the person who is trying to update the conference, and the meeting is deleted from the Site Conferencing Calendar mailbox that is used to provide users with the conference meeting information.
Extending a Conference
If a customer tries to extend a currently running conference through Microsoft Outlook past the maximum lease time for the video provider.
Scheduling a Conference with Microsoft Outlook 97 or Microsoft Outlook 98
If you try to schedule a conference against an overbooked resource in asynchronous mode (user unable to access resource's free-and-busy information) using clients such as Microsoft Outlook 97 or Outlook 98. You may also receive the message if the Site Conference Calendar mailbox exceeds the size limit for that mailbox.

RESOLUTION

Set the properties for the video conference resource to be identical to the currently used resource before you try to change the resource.
Extend the conference within the Maximum conference extension time in minutes parameter specified by the Video Conferencing Provider.
Verify that the conferencing resource's free-and-busy information is free for the time requested.
