I've done everthing I should; i.e. on Tools, Options, Mail Setup tab, Send
immediately when connected is checked. Then under Send/Receive button, I
have one group with all my email accounts included and the box is checked
which says Schedule an automatic send/receive every 5 minutes.

But when I start Outlook, automatic send/receive function does not work, nor
does the 5 minute send/receive work. I have to click on the Send/Receive
button on the toolbar in order send or receive email. It used to work and
then I changed it to unchecked both places. Later I came back and checked
them again, but it has never worked since rechecking them.

I tried using Help to find the answer, but there is no answer for this
specific problem. I have used Outlook for many years and am very familiar
with the Tools Options menus. Why is it doing this? What am I doing wrong
or leaving out?
