RGES Cloud Implementation: inspector and explorer windows pinning state separated

Separate Outlook Sidebar pinning mechanisms are used in two different view modes explained below. If the Sidebar is pinned for automatic opening in one mode, it will not be auto-opened in another mode.

These types are:

1. Inspector MS Outlook view: when an email is selected in the Inbox or Sent folder and displayed in MS Outlook main pane

2. Explorer MS Outlook view: when an email is opened in a separate window by double-clicking on it or by composing a new email, a replying, or forwarding

This separation allows the end users to set Sidebar pinning according to their preferences in different contexts.


If you close the Sidebar by clicking the x icon in its upper right corner, the actual pinning state will be lost
