This article was previously published under Q195113 IMPORTANT: This article contains information about modifying the registry. Before you
modify the registry, make sure to back it up and make sure that you understand how to restore
the registry if a problem occurs. For information about how to back up, restore, and edit the

SYMPTOMS
If you use Netscape Navigator 3.x or 4.05 to check e-mail messages on
Exchange Server computers, Navigator is unable to open attachments.
When you attempt to open the attachment, a Save As dialog box appears.
Your only option is to save the file and open it later.
CAUSE
Although Internet Explorer can open attachments properly based on file
extensions, Netscape Navigator requires that the correct content type be specified.
If the server does not have the association of the content type with an extension in
the registry, then Navigator does not get this information. An example of
the association in the registry is .DOC = application/msword.
WORKAROUNDWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
For problems with Microsoft Word document attachments, ensure that the
following registry subkey and value exist:
Value Name: Content Type
Value Data: application/msword
Because the problem is not specific to attachments with the .doc extension,
you need to ensure that other extension types are defined in the
following subkey:
HKEY_CLASSES_ROOT \extension type
After you add the value above, you need to restart your computer.
Stopping and restarting the Exchange Server services and Web services does not
work.
Failure to restart results in ASP 0115 errors in the client after the
change has been made in the registry.
STATUSMicrosoft has confirmed that this is a problem in Microsoft Exchange Serverversion 5.5.
