Too many ' tasks' when checking email


Outlook version
Outlook 2010 64 bit
Email Account
I have a new mcomputer with Windows 7 and Outlook 2010. I use Comcast, and have only 3 email addresses set up. When I click 'send/receive' I can see the screen that comes up that says, "Outlook send/receive progress". and it goes through 1 to 6 tasks and then again 1 to 11 tasks. I can see my 3 emails listed many times. On the 1 to 6 list it checks each of my 3 emails for send once and receive once, and I understand those 6 total checks. BUT, when it then goes again to 1 to 11 tasks after it goes through 1 to 6 tasks, it lists my same 3 emails again. This all takes up to a few minutes or so to complete. My question is how to eliminate those other 1 to 11 tasks, so my computer will just check the proper 1 to 6 tasks, one send and one receive for each of my 3 email addresses which totals 6 tasks. How would I correct this problem????
