Cisco Unity is sending messages that are destined for a Microsoft Exchange user’s mailbox to the
Unaddressed Messages distribution list instead.
Which of the following is most likely the cause of the problem? (Select the best answer.)
A.
The Issue Warning storage limit has been exceeded.
B.
The Prohibit Send storage limit has been exceeded.
C.
The Prohibit Send and Receive storage limit has been exceeded.
D.
The Cisco Unity user’s dn does not match the dn configured in UCM.
E.
The Message Age limit has been exceeded.
Explanation:
Most likely, the Prohibit Send and Receive storage limit has been exceeded if Cisco Unity is sending messages
that are destined for a Microsoft Exchange user’s mailbox to the Unaddressed Messages distribution list
instead. 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 systemwide 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 Prohibit Send and Receive storage limit 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.
It is not likely that the Message Age limit has been exceeded. If a Message Age limit were exceeded, voice mail
messages would either be moved to the Deleted Items folder or be permanently deleted by Cisco Unity, which
would prevent the mailbox from becoming full. 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.
It is not likely that the Issue Warning storage limit has been exceeded. 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 beforestricter mailbox size enforcement measures are activated.
It is not likely that the Prohibit Send storage limit has been exceeded. When the Prohibit Send threshold is
exceeded, neither Cisco Unity nor Microsoft Exchange will allow the user to send messages. However,
messages will still be delivered to the user’s mailbox.
It is not likely that the Cisco Unity user’s directory number (dn) does not match the dn configured in Cisco
Unified Communications Manager (UCM). Mismatched dns can become a problem when UCM users are
imported into Cisco Unity Connection, not Cisco Unity. When a user’s dn in UCM does not match the same
user’s dn in Cisco Unity Connection, the user will not be able to receive voice mail messages and will not be
able to log in to voice mail services.https://www.cisco.com/en/US/docs/voice_ip_comm/unity/402/administration/guide/ex/
