SYMPTOMS
Consider the following scenario. You open a meeting request on an Internet Message Access Protocol 4 (IMAP4) client computer. Then, you log on to Outlook Web Access and open this meeting request again. In this scenario, you may receive a 404 error message that resembles the following message:

Page not found.



CAUSE
This problem occurs because the URL that the IMAP4 client creates for the meeting request uses an incorrect format.

MORE INFORMATION
The following situation is an example of this problem. The account &quot;testuser&quot; has the following primary SMTP address:

test.user@. .com

The main domain name is &quot; .com&quot;. In this example, the IMAP4 client keeps &quot;test.user&quot; in the primary SMTP address as part of the URL. When Outlook Web Access in Exchange Server 2003 SP2 tries to interpret the URL, Outlook Web Access automatically appends the main domain name &quot; .com&quot; to &quot;test.user&quot;. Then, Outlook Web Access uses the &quot;test.user@ .com&quot; SMTP address to search for the &quot;testuser&quot; account. However, &quot;test.user@ .com&quot; does not exist. Therefore, Exchange Server 2003 SP2 returns a 404 error.
