When I open up my laptop in the morning, it takes Outlook 30-40 minutes (or more) to get any new mail.  At the bottom of the screen, it says Inbox: Determining Changes ... with a candy-strip bar that goes on for a really long time.  If I look on my iPhone, all the mail is already there, but with Outlook, I have to wait and wait and wait.  Eventually, it all comes in a flood.  And then, as long as I don't put my laptop to sleep, it seems to keep up on a normal schedule.

I have 3 iMap accounts (gmail), and one Exchange (Office 365) account.

I'm using a MacBook Pro running OS X 10.9.5 w/ 8gb of RAM.  Running Outlook for Mac v14.4.7 as part of Office for Mac 2011.

This problem has been going on for quite a while - I've just been tolerating it and am finally fed up enough to want to do something about it.
