Explanation:
An administrator is most likely to recommend that a Single Inbox user disable the Microsoft Outlook Mark
Messages as Read When Viewed in the Reading Pane option if the message waiting indicator (MWI) lamp
turns off before a message is read in Microsoft Outlook. The Single Inbox feature of Cisco Unity Connection
enables the synchronization of voice messages between Cisco Unity Connection and Microsoft Exchange
Server mailboxes. For example, a voice mail left for a Cisco Unity Connection user can additionally be delivered
to that user’s Microsoft Outlook Inbox. If the Mark Messages as Read When Viewed in the Reading Pane
check box in the Outlook Options > Mail > Reading Pane dialog box is selected, the MWI lamp will turn off
when the user selects the message in Outlook’s reading pane and there are no more new messages in Unity
Connection.
An administrator is not likely to recommend that a Single Inbox user disable the Microsoft Outlook Mark
Messages as Read When Viewed in the Reading Pane option if no Single Inbox features are working.
However, an administrator might verify that the Cisco Unified Messaging Service is enabled and running in
Cisco Unity Connection if no Single Inbox features are working for the group of users that is associated with
that Cisco Unified Messaging Service instance. In order for these features to be available, the Cisco Unified
Messaging Service must be enabled and started.
An administrator is not likely to recommend that a Single Inbox user disable the Microsoft Outlook Mark
Messages as Read When Viewed in the Reading Pane option if messages are sent to the wrong email
account. However, an administrator might verify that the user’s primary or proxy Simple Mail Transfer Protocol
(SMTP) address in Unity Connection matches the account to which the user wants voice mail messages
relayed.
An administrator is not likely to recommend that a Single Inbox user disable the Microsoft Outlook Mark
Messages as Read When Viewed in the Reading Pane option if secure messages cannot be played in Outlook.
However, an administrator might verify that Cisco Unity Connection ViewMail for Microsoft Outlook is installed
on the user’s workstation if secure messages cannot be played in Outlook. When Unity Connection delivers a
secure voice mail to Microsoft Exchange, only the introductory text of the email is sent to the user. The audio
file containing the message remains on Unity Connection. Cisco Unity Connection ViewMail enables users to
listen to the voice mail audio files.
