ID: Q170655

The information in this article applies to:

SYMPTOMS

When you use the AutoDialer to make a call to a Microsoft Outlook 97 Contact, you may receive the following error message:

   Outlook caused a stack fault in module KERNEL32.DLL at 0137:bff72408

CAUSE

This error message may occur when you hang up before completing the call, and then try to make another call before the Call Status dialog box is closed.

WORKAROUND

To work around this problem, wait until the Call Status dialog is closed before initiating another call.

On some modems, selecting the FIFO buffers option will increase the response speed of the modem, and reduce the likelihood of the error. To select the FIFO buffers, choose the appropriate method from the following.

In Windows 95

If you are running Windows 95, follow these steps:

1. Click the Start button, point to Settings, and then click Control Panel.

2. In the Control Panel, double-click the Modems icon.

3. On the General tab, click to select your modem, then click Properties.

4. On the Connection tab, click Port Settings.

5. Click to select "Use FIFO buffers (requires 16550 compatible UART)."

6. Click OK twice, and then click Close.

In Windows NT

If you are running Windows NT, follow these steps:

1. Click the Start button, point to Settings, and then click Control Panel.

2. In control Panel, double-click the Ports icon.

3. Click to select the modem port and then click Settings.

4. Click Advanced.

5. Click to select FIFO Enable.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Outlook 97. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

When you click Hang Up in the Call Status dialog box, it may take a while for the dialog to be closed, especially with a slow modem. If you attempt to dial another contact while the Call Status dialog is still open, you receive the error message described in the "Symptoms" section of this article.
