Frequent checking breaks your concentration and interrupts what 

you’re doing, wasting time as you return your focus to the task 

at hand. Reduce how often your e-mail client checks for new 

messages to something less distracting: Every 10 or 15 minutes 

should give you time enough to focus without keeping people 

waiting overly long for a response. In Outlook, click S and tweak 

the digits for ‘Schedule an automatic send/receive every minutes’.
