I'm running Office Pro 2003 SP2 on all my workstations, along with Outlook 2003. Last night I tried switching to non-Cached mode to see what would happen and although I was pleased with being able to receive an email as soon as it's sent, I found if I tried sending an email myself, it would just sit in the Outbox and never send. The option "Send immediately when connected" is ticked and it seems to send either when an email is received, the Send/Receive button is pressed, or if I click into the Outbox folder. Is there any reason behind this issue?
Additionally is there really any benefit from using this mode, seeing as it'll make Outlook absolutely useless to you if the server fell over? Or is it meant to be used in an environment where cluster servers are present?
