To work around this problem, do not use a comma or an extended character in a display name.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Outlook Express 6.0 and Outlook 2003 use the Inetcomm.dll file to parse message headers that are received by using a POP3 e-mail account. When the display name contains only a comma and does not contain an extended character, the display name for the From field is enclosed in quotation marks. When the display name contains both a comma and an extended character, the From field looks similar to the following example:
From: =?iso-8859-1?Q?Garaikoetxea_Mu=F1oa=2C_firstname_Mari_=28lastname_POP3=29?= <e-mail address>When Outlook Express parses the From field, it considers the comma as a separator if the string is not enclosed in quotation marks.
If you send a message when the conditions that are listed in the "Cause" section are true, more than one message may be sent. In this scenario, one message contains the correct and complete SMTP e-mail address. The other message contains an incorrect or incomplete SMTP e-mail address. If a recipient receives the message that contains an incorrect or incomplete SMTP e-mail address, the recipient cannot reply to the message.
