To avoid “Access Deny” error while sending messages
If you have applied Microsoft patch ms06-029, when an AltiGen PBX phone user attempts to send a message,
the user receives an "Access Deny" error. This is because the patch changes the grant for the permission of
Send As
.
After applying the patch, the Send As permission of each user needs to be granted to the account of “altigen
service” explicitly.
You may have to restart the Exchange Server and MAXCS.
Notes
• Prevent attempts by the Exchange Administrator/Manager to use the existing service account for the
AltiGen Exchange Integration Service. Using the AltiGen service account will provide you an audit trail that
is invaluable while troubleshooting.
• Depending on the number of voice mails you have on the AltiGen server, the initial mailbox
synchronization may take a long time.
For example, if you have 10GB of voice mails on the AltiGen server and are enabling Exchange integration
for all the mailboxes, it may take up to 24 hours to initialize the Exchange integration service.
On the other hand, if you have less than 100MB of voice mails on the AltiGen server, the initialization will
take less than 5 minutes.
• If users experience a problem making calls to the Exchange server, make sure the MSXML 6.0 Parser
has not been deleted from the server. Without it, the speech engine services cannot play voice prompts.
