When you have pages open in the browser does it refresh itself?

The President of our company is having speed issues with outlook and I've noticed, that she has over 15 web pages open all at the same time.  
When web pages are open do they refresh themselves and in doing so use up bandwidth.  
We use Office 365 with outlook 2013 on the computers

The web page determines whether or not it refreshes by itself.

I do not think this causes the use of much bandwidth.  Perhaps having "over 15" pages open at the same time is much more likely to be the problem.

Perhaps too many programs running in the background.  Run Process Explorer to see which are running and whether she really needs them to run all the time.

What are you comparing speed to?  Is this something new?  If so, perhaps a System Restore.  
Are you getting any error messages?

The only time that 15 windows open will cause a problem is if they include sites like Yahoo and Facebook that are continuously refreshing their pages with JavaScript.  That is becoming more and more common with sites like that.

it could be a memory issue. The only real way is to check.. is outlook in cached mode? is the computer cpu bound / i/o bound / out of memory causing disk trashing?
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Because we use Office 365, I believe the issue is the sync between outlook and office 365.  For example she opened a folder in outlook she has opened in over 6 months.  So outlook had to sync with Office 365.

Your thoughts?

I think setting her cache to "all" is a great idea.  I did it this morning at 9am, it's now 6 pm and it's still updating the folders.  11000 in the inbox and 18000 in deleted.  Can you say hoarding?

Do folders in outlook only get synced when you access them or constantly?
David Johnson, CD, MVPOwnerCommented:
if you do a send recieve it normally syncs all folders. and you will see all folders up to date. or you can just update the folder. there are too many options that control this
