SYMPTOMS
You may not be able to use Microsoft Outlook Web Access (OWA) to open a message in the Exchange 2000 Server information store. However, if you use Microsoft Outlook, you can open the message without any problem. When you use OWA to open, reply to, or forward the message, the browser may return an &quot;Action Canceled&quot; or &quot;File not Found&quot; error message. This problem occurs with messages that contain a long subject (more than 256 characters) in which the 256th character is a space. OWA may also not open a Non-Delivery Report (NDR) message that has a space in the subject line.



CAUSE
Exchange 2000 server uses the PR_URL_COMP_NAME property to identify a message. This property is based on the subject property and has a limitation of 256 characters. This problem can occur if the subject size is larger than 256; all of the trailing characters are removed when the PR_URL_COMP_NAME property is constructed. If the 256th character is a space, the construction generates an incorrect value.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

301378 XGEN: How to Obtain the Latest Exchange 2000 Server Service Pack

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

Component: Information store



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 2.



MORE INFORMATION
When you apply this fix, new messages that contain a long subject (more than 256 characters) in which the 256th character is a space will successfully open. However, with any existing messages in the information store you will still experience the behavior described in the &quot;Symptoms&quot; section. You can remove these existing messages manually.
