Chapter 18 Configuring Advanced Voice Mail
Configuring IMAP
If this feature is enabled in SSL mode only, verify that the e-mail client is configured to use SSL
connections to the IMAP server.
The same subscriber can connect to Cisco Unity Express from one or more e-mail clients using one or
more connection types (SSL or non-SSL). Each session counts against the maximum number of
connections allowed to the IMAP server.
Subscribers cannot retrieve the following types of messages from their personal mailboxes:
• Broadcast messages
• Private messages
The voice-mail messages are downloaded as .wav attachments to the Inbox folder of the e-mail clients.
If a subscriber receives a new message or saves a voice-mail message in the Inbox folder, the
Cisco Unity Express retains the message in its database. If mandatory message expiry is enabled on
Cisco Unity Express, the message is subject to the expiry timer.
If a subscriber moves a voice-mail message from the Inbox folder to another folder on the e-mail client,
Cisco Unity Express deletes the message from its database. Mandatory message expiry would not affect
that message.
Note Mandatory message expiry is not enforced on e-mail clients but is enforced on messages in the
Cisco Unity Express database.
Cisco Unity Express supports the following operations on the e-mail clients:
• Mark Read/Unread
The Mark Read operation on the e-mail client is equivalent to Message Save on the voice-mail
system. Similarly, the Mark Unread on the e-mail client is equivalent to the Mark New on the
voice-mail system.
• Delete/Undelete
• Expunge (Purge)
Errors displayed on the e-mail clients are dependent on the client implementation. See the client
documentation for more information.
The protocols supported determine the port that the IMAP client uses to connect to Cisco Unity Express.
Table 18-2 lists the supported ports for Cisco Unity Express 8.5 and earlier. Table 18-3 lists the
supported ports for Cisco Unity Express 8.6 and later.
