We use OWA on exchange 2003 and it works well. Now thing is we want some users to open different users mailbox via owa but when the use the url http:\\servername\exchange\mailbox
name it gives page cannot be displayed on some of them. Now the reason i say page cannot be displayed on SOME of them is it seems that if the mailbox name does not contain any spaces it works so for example this will work http:\\servername\exchange\info
works no problem but http:\\servername\exchange\me
you gives page cannot be displyed 404 error.
