The Fax feature stops working in Exchange Server 2007 SP3


The Fax feature stops working after you apply Microsoft Exchange Server 2007 Service Pack 3 (SP3).


This issue can occur if the following conditions are true:
  • The Fax system is configured to send an inband fax tone.
  • The EnableInbandFaxDetection setting is set to False in the Globcfg.xml file.


To resolve this issue, change the Globcfg.xml file. To do this, follow these steps:
  1. Open the Globcfg.xml file in Notepad.

    Note By default, the Globcfg.xml file is located in the following folder on a server that is running Exchange Server 2007 and on which the Unified Messaging server role is installed: 
    \Program Files\Microsoft\Exchange\bin
  2. Edit the EnableInbandFaxDetection entry as follows:
  3. On the File menu, click Save.
  4. Exit Notepad.

More Information

Exchange Server 2007 SP3 replaces the Globcfg.xml file. By default, the EnableInbandFaxDetection setting in the Globcfg.xml file is set to False. Therefore, the Fax feature may not work as expected in Exchange Server 2007 SP3.
