We use Windows Server 2003 and Exchange Server 2007 Std. We have troubles with OWA. Every user is able to login and the OWA interface is on. If I for example go to Deleted Items then select the message to delete and click an icon of deleting I get the message window with the question to approve and when I click OK I get the message "Microsoft Exchange generated unexpected respons (404)". And the message is not deleted. The same message appears when I try to write new message I get new message window displayed and immidiately the above mentioned message (404). The new mail message window stays on screen I can fill it. But when I clik "Send" the 404 message appears again and the mail is not send. What should I check to solve the problem?
