Mail Server Adapter Types

NuPoint Unified Messaging supports the IMAP messaging protocol as adapter types for connecting to email servers for voice mail synchronization and Text-to-Speech ( TTS).

IMAP

The IMAP connector, which is deployed by default on NuPoint Unified Messaging, supports Microsoft Exchange Server 2013 and 2016, Microsoft Office 365 and Google Apps. The IMAP connector only supports one email server so it is targeted for small and medium-sized companies with one email server. Up to 1500 Advanced UM users are supported with Exchange and up to 750 Advanced UM users are supported with Office 365, and up to 2500 users are supported with Google Apps (Gmail).

To set up the email server for IMAP, see the following procedures:

Note: In most cases, voice mail messages are sent immediately to the email server and then forwarded to the Advanced UM users. However, hosted email configurations such as Google Apps may experience slight delays due to virus scanning, anti-spam software, or routing delays caused by traffic volume. As a result, the timestamps of the original voice mail message and email audio attachment may not match.

When using IMAP with MS Exchange Server, you can create a superuser account ( NPUMAdmin) for Advanced UM. Because NPUMAdmin has more privileges than the administrator account, it can access user accounts and inboxes in order to synchronize their voicemail and email messages.
