This feature requires you to use a Microsoft Exchange Server 2007 account. Most home and personal accounts do not use Microsoft Exchange. For more information about Microsoft Exchange accounts and how to determine which version of Exchange your account connects to, see the links in the See Also section. Your Exchange 2007 administrator must enable the Unified Messaging feature for these commands to be available.
You can configure multiple voice mail options. These options include resetting a Microsoft Office Outlook Voice Access PIN, voice mail greetings, and missed call notifications.
A voice mail greeting is a greeting that callers hear before they leave a voice mail message. When you select the Voice mail greeting option, a voice mail greeting is played to callers. When you are out of the office and the Out of Office voice mail greeting is selected, callers hear an Out of Office voice mail greeting. By default, a standard voice mail greeting is played to callers. However, you can record personal voice mail greetings by using the voice mail options that are available in Microsoft Office Outlook 2007.
Note: The voice mail options found in Office Outlook 2007 are also available in Microsoft Office Outlook Web Access.
On the Tools menu, click Options.
Click the Voice Mail tab.
In the Voice Mail section, under Choose the greeting played to callers, select the greeting to play to callers.
