The "All Project Email" activity view can be used to see all messages that have been received to all projects and tasks which you are currently allowed access. E-mail messages which have not yet been read are marked with a bold font. E-mail messages which have been read are marked with a normal font.
The "All Project Email" activity view is almost exactly the same as a Task Detail Messages tab with two important exceptions.
First, the "All Project Email" activity view shows e-mail messages across all projects.
Second, the "All Project Email" activity view does not contain an e-mail action command bar. E-mail actions must be set at the task or project level.
Due to the similarities between this tab and the task detail messages tab the "All Project Email" activity view will not be discussed in detail again here. For more information on this control please see the Task Detail Messages tab.
