Manager is unable to respond to a meeting invite

When a manager (in a manager-delegate pair) opens a meeting invite, they do not see the Accept, Tentative, or Decline options under the Change Response control. Instead, they see only No Response Required in the Respond section of the ribbon, as shown in the following figure.

More Information

If a manager is configured with the default delegate setting where they receive informational meeting items, they will not be able to act on a meeting invite if they view it in the reading pane. This is demonstrated in the following figure.

However, the manager can Accept or Decline a meeting if they open the meeting invite in an inspector window (double-click on the item to open it). If DisableResponseButtons=1 in the registry, then they will not be able to act on meeting invites when they open them.
