APPLIES TO


 * Microsoft Exchange Client 4.0 for Macintosh

-



This article was previously published under Q156721



SYMPTOMS
When you double-click on a file attachment in the Microsoft Exchange Macintosh client, it might open a new message and insert the attachment into the new message.



CAUSE
This will occur if the Microsoft Exchange Macintosh client does not recognize the file attachment. This happens when the attachment does not have a Mac creator or type, or there is no mapping from the file extension, creator, or type. The unrecognized file attachment will be stamped with a creator of 'EXCH' and a type of 'XCAT' and this will cause the Microsoft Exchange Macintosh client to open a new message.



WORKAROUND
To correct this problem, use a program such as ResEdit or the shareware Snitch More Info plug-in to reset the creator to '' and the type to '????' on all saved attachments. This will prevent the Microsoft Exchange Macintosh client from starting when these documents are clicked.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft Exchange clients, version 4.0, listed at the beginning of this article. This problem was corrected in Microsoft Exchange Server 4.0 U.S. Service Pack 4. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base:

SERVPACK



MORE INFORMATION
This fix corrects the reported problems for all attachments received after this version of the Microsoft Exchange Macintosh client is installed. It will not fix this problem for attachments received and saved prior to the installation of this fix.
