SYMPTOMS
When you try to open messages with the Outlook Web Access (OWA) client with Microsoft Exchange Server, version 5.5 Service Pack 1, you may receive the following error message:

HTTP Error 404 File Not Found. The Web server cannot find the file or

script you asked for. Please check the URL to ensure that the path is

correct. Please contact the server's administrator if this problem

persists.



CAUSE
The URL path for messages is incorrect. The OWA client is looking for a message path of: javascript:parent.openNewWindow("/exchange/forms/IPM.NotefrmRoot.asp?...

Instead of:

javascript:parent.openNewWindow("/exchange/forms/IPM/Note/frmRoot.asp?.. There is a calculation and check done on the files in the Webdata directory to determine if the object is a file or a directory. If some flags (such as Archive or Compressed) are set on the directory, it may cause the calculation routine to be incorrect and produce the wrong URL.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: Outlook Web Access   File Name     Version ---  Cdohtml.dll   5.5.2404.0



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 first corrected in Exchange Server 5.5 Service Pack 2.



MORE INFORMATION
Download the compressed Setup file appropriate for the server for your hardware platform. Select the appropriate files as indicated by the following list:      Alpha AXP(TM)     Psp1cdoa.exe Intel(R)         Psp1cdoi.exe  Download appropriate file to a temporary location on the server's local hard drive.

Example: To download the English version for the Intel platform, visit the following Microsoft Web site:

ftp://ftp.microsoft.com/bussys/exchange/exchange-public/fixes/Eng/Exchg5.5/PostSP1/CDOHTML-fix/Psp1cdoi.exe

 Unzip the file by typing the file name of the self-extracting archive at the command prompt.

Example: The version for the Intel platform will be Psp1cdoi. Stop the World Wide Web Publishing Service and the Internet Information Server (IIS) Administrator Service (if you are using IIS 4.0). Rename your existing Cdohtml.dll in your Exchsrvr\Bin folder to Cdohtml.old.</li> Copy the included Cdohtml.dll to your Exchsrvr\Bin folder.</li> Copy the included Cdohtml.dbg file to your Winnt\Symbols folder (optional).</li> Click Start, Run, and in the text box type:

regsvr32.exe :\exchsrvr\bin\cdohtml.dll

This will register the Cdohtml.dll.</li> Click OK on the dialog box stating the Cdohtml.dll was registered successfully.</li> Start the World Wide Web Publishing Service and the Internet Information Server (IIS) Administrator Service (if you are using IIS 4.0).</li> The Exchange Server computer should be updated successfully now, and you should no longer get the HTTP 404 error when opening messages.</li></ol>

After you apply Service Pack 3 and verify that Cdohtml.dll is the proper version, if the problem continues to occur, uninstall the OWA component, delete the Exchange virtual folder in IIS (if it still exists), delete the Webdata folder off of the file system, and then, re-install OWA and SP3.
