DOCUMENT:Q149290 24-MAR-1999 [exchange] TITLE :XCLN: Renaming Attachment Doesn't Change File Association PRODUCT :Microsoft Exchange PROD/VER:WINDOWS:4.0,5.0 OPER/SYS: KEYWORDS:kbusage ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0 - Microsoft Exchange Windows 3.x client, versions 4.0, 5.0 - Microsoft Exchange Windows NT client, versions 4.0, 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== If you rename an attachment, the file association for that attachment does not change. Therefore, the original application will still start when that attachment is activated. CAUSE ===== When you attach a file in a mail message, the name and extension are stored internally. If you rename the attachment giving it a different extension, the file association is not changed. For example, if you receive a Test.dat attachment and rename it to Test.doc, double-clicking it will not launch Word as expected. RESOLUTION ========== This is by design. This way the user can change the name to something like "My most excellent document" with having to worry about adding a .doc extension to it. If you choose the Save As option, you will still see the original attachment name. STATUS ====== This behavior is by design.
