A user with an Avaya Aura Messaging mailbox on a Zimbra server does not receive voice mails deliver to the Zimbra mailbox even though the user's colleagues have been leaving messages. Other users with Zimbra mailboxes are receiving their voice mails. The other users who are receiving their voicemails are on a different Zimbra mailbox server even though the Zimbra LDAP server is the same for all users. What is the first step you would use to diagnose the problem?
Check the SMTP Connection diagnostic from the Messaging SMI.
Check the active alarm log.
Re-administer the Zimbra server.
Send an email message to the user's Zimbra e-mail address.
