Cause

When the System Attendant resource goes offline, it tries to shut down any child tasks. One child task tries to contact all Public Folder servers in the top level hierarchy. If there are many public folder servers in the Exchange organization, this procedure takes a long time. Therefore, the SA resource times out. Because of this, the SA resource may stay in the "Offline Pending" state on the failed node of the cluster or it may stay in the "Online Pending" state on the node to which it is failing over.
