SYMPTOMS
If you write a client extension DLL shell which registers for IExchExtAttachedFileEvents, when you double-click to open a file attachment from the preview pane, OnWritePattFromSzFile is called and OnOpenSzFile is not called. If you first open the message and then double-click the attachment to open it, both OnWritePattFromSzFile and OnOpenSzFile are called.



RESOLUTION
To resolve this problem, obtain Microsoft Office 2000 Service Release 1/1a (SR-1/SR-1a).

To obtain SR-1/SR-1a, click the article number below to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was corrected in Microsoft Office 2000 SR-1/SR-1a.



MORE INFORMATION
Open an attachment that is showing in the preview pane. OnOpenSzFile for the extensions do not get called. The ramifications are that extensions that attempt to add security for opening attachments do not work. The user can circumvent the security by opening the attachment from the preview pane.
