Troubleshooting Active Directory and Exchange Server Connectivity with NetVanta UC
ADTRAN NetVanta UC Server is a real-time communications system that integrates with Microsoft® Active Directory and Exchange Server (versions 5.x and above) to provide advanced unified messaging functionality. This technical note provides troubleshooting methods to resolve problems when connecting to these network resources.
For a list of initial requirements that must be met to integrate with Active Directory and Exchange Server, please see the ADTRAN NetVanta UC Server Planning and Deployment Guide.
To enable single sign on (SSO) authentication and integration with Microsoft Exchange Server, the following prerequisites must be met:
If access to the domain controller(s) is interrupted, the Application Service may restart to attempt to reconnect to Active Directory, and then fail to start if unable to contact a domain controller. Voice mail and other services will be unavailable during the restart. A fault-tolerant Active Directory infrastructure is highly recommended. Design and maintenance of Active Directory is the responsibility of the user.
UC Server connects to Exchange Server in a similar manner to Outlook clients and RIM BlackBerry™ Enterprise Server using the Microsoft™ Messaging API (MAPI) protocols. If Outlook clients and/or BlackBerry Enterprise Server are not able to connect to Exchange or are experiencing similar issues to UC Server, first ensure that the Exchange Server infrastructure is available and operating properly.
If UC Server is the only Exchange Server client that is experiencing the issue, there may be a problem accessing the service account mailbox or the Exchange Server itself from the UC Server computer. Ensure that the server name and mailbox are set correctly in UC Client; see the NetVanta UC Server Administrator Guide. To verify connectivity to Exchange Server apart from the UC Server software, use the Outlook installation or the third-party MFCMAPI utility (http://mfcmapi.codeplex.com).
The following procedures will assist in the verification or troubleshooting of proper domain and Exchange setup and permissions. Please note that these steps are provided as a courtesy only, and ADTRAN Technical Support will not assist in troubleshooting any problems encountered while using the Microsoft™ programs.
To verify privileged Exchange Server access using MFCMAPI in Exchange 2013
*Instructions based on version 220.127.116.112, 32-bit - NOTE, this process is only valid in Exchange 2013
To verify privileged Exchange Server access using MFCMAPI in Exchange 2010 and previous versions
*Instructions based on version 18.104.22.1684, 32-bit - NOTE, this process is not valid in Exchange 2013
It can be normal to see mailbox properties with error codes, and these can be ignored in most cases:
As long as MAPI does not return an error code such as the following when accessing the mailbox, the Exchange connection and permissions are operating properly in most cases. If any errors like these are encountered, they will need to be troubleshot separately with the Exchange administrator before calling ADTRAN Technical Support. If MFCMAPI is unable to open another user’s mailbox, ADTRAN will not assist in troubleshooting why the NetVanta UC Server is unable to access the mailbox.
To verify privileged Exchange Server access using Microsoft Outlook 2007
*As of UC version 5.0 and above, Microsoft™ Outlook is no longer supported as a connection method to Exchange. Instead, the MAPI-CDO tools are now a required part of any upgrade or installation. Thus, the following instructions are only relevant for older installations of NetVanta UC Server that have Microsoft™ Outlook installed on the same server.
