We have a customer that has Entourage 2008 set up on his Mac - connecting to an Exchange 2003 server hosted by Fasthosts.
The problem is when he sends emails, they appear to send OK - as in they appear in his Sent Items folder, but half of the time they never arrive.
There is no such problem with the mailbox when using OWA, and these same emial that do not send also appear in the Sent Items in OWA (i.e. email sent using Entourage show up in OWA Sent Items)
Fasthosts are no help - saying only the problem is Entourage not them.
Can anyone help??
