Bandwidth Rule for Microsoft Store Downloads

Hello,

this morning about 800 clients updated their Windows Store apps (.appxbundle) at the same time and used all our available bandwidth. We have bandwith control in place, but the first rule is for Office 365 which gets the highest priority. It seems that the Windows Store traffic was also in this Office 365 bandwidth rule (see below for the configuration of this bandwidth rule) and as a result the access to Exchange Online and almost all web application was slow. Can I remove Windows Store apps from the Office 365 bandwidth rule and have a dedicated rule for Windows Store apps download to limit the maximum bandwidth?

Best Regards,
Patrick
