XCLN: IE Mail Button Prompts You to Choose Profile

• Microsoft Exchange Windows 3.x client, version 4.0
• Microsoft Exchange Windows NT client, version 4.0
• Microsoft Exchange Windows 95 client, version 4.0
• Microsoft Internet Explorer 3.0x

SYMPTOMS

In Microsoft Internet Explorer version 3.0x, when you click Mail, Read New Mail, Send Message, or Send a Link, you are prompted with the Choose Profile dialog box. This occurs regardless of how Microsoft Exchange Client is configured

This occurs even if you specifically cleared the "Prompt for a profile to be used" checkbox in the Exchange or Outlook client (on the Tools menu, click Options).

This behavior does not occur if you have logged on to the Exchange or Outlook client prior to opening the Mail button.

CAUSE

This is expected behavior of the MAPI call being made by Internet Explorer. Other applications that make this MAPI call exhibit this same behavior.

MORE INFORMATION

Further explanation from the MAPI Software Development Kit (SDK):

   MAPI client applications call the MAPILogonEx function to log onto a
   session with the messaging system. It is the client's responsibility
   to call service providers; MAPILogonEx does not make these calls. All
   strings passed in and returned to and from MAPI calls are null-
   terminated and must be specified in the current character set or code
   page of the calling client or provider's operating system. The
   lpszProfileName parameter is ignored if there is an existing previous
   session that called MapiLogonEx with the MAPI_ALLOW_OTHERS flag set and
   if the flag MAPI_NEW_SESSION is not set. If the lpszProfileName
   parameter is NULL or points to an empty string, and the flFlags
   parameter includes the MAPI_LOGON_UI flag, the MAPILogonEx function
   generates a logon dialog box with an empty field for the profile name.
