If you configure Microsoft Outlook 97 in Internet Only Mode (IMO) to use an Exchange 2000 server for the SMTP server, and you send a message that contains an attachment with a long file name, the attachment may not be sent correctly. The file name of the attachment may be truncated after the first space in the file name.
This problem can occur if Store.exe incorrectly parses the X-MS-Attachment: header when Store.exe parses the header of the e-mail message. To obtain the attachment name, the code obtains the line from the header, and then searches for the first space. Exchange 2000 appends "\0" (without the quotation marks) after that space, which truncates the file name.
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
