Which of the following is not a Microsoft Exchange storage limit that can be addressed in a Cisco Unity phone
conversation?

A.
Issue Warning

B.
Prohibit Send

C.
Prohibit Send and Receive

D.
Message Aging

Explanation:
Message Aging is not a Microsoft Exchange storage limit. Therefore, a Cisco Unity phone conversation cannot
address a Message Aging storage limit. Message Aging is a Cisco Unity option that can be used to move voice
mail messages of a given age to the Deleted Items folder, or delete them permanently. This option is disabled
by default. However, you can enable this option as a more permanent solution for a user who has a high
volume of inbound voice mail messages that are never manually deleted.
Cisco Unity integrates voice messaging with email services provided by Microsoft Exchange. In a Cisco Unity
and Microsoft Exchange environment, voice messages, email, and fax messages can all be accessed from the
same client, such as a PC or a touchtone phone. When a user’s mailbox exceeds Microsoft Exchange storage
limit thresholds, Cisco Unity can notify the user by using the phone conversation.Microsoft Exchange has three different storage limit thresholds that can be configured system-wide or on a peruser basis. When a user’s mailbox size exceeds a configured threshold, Microsoft Exchange and Cisco Unity
carry out different actions depending on the storage limit that applies.
When the Issue Warning threshold is exceeded, both Cisco Unity and Microsoft Exchange will send a
notification to the user that the mailbox has exceeded the threshold. The warning gives users an opportunity to
delete or archive old messages before stricter mailbox size enforcement measures are activated. When the
Prohibit Send threshold is exceeded, neither Cisco Unity nor Microsoft Exchange will allow the user to send
messages. When the Prohibit Send and Receive threshold is exceeded, neither Microsoft Exchange nor Cisco
Unity will allow the user to send or receive messages. In addition, Cisco Unity will forward any messages that
cannot be delivered to its Unaddressed Messages distribution list. Messages that are forwarded to the
Unaddressed Messages distribution list will not be delivered to the intended recipients.
