mallama -> High SMTP Traffic After Migrating One Mailbox to Office 365 (9.Nov.2014 12:09:54 PM)

We are currently do a staged migration from Exchange 2007 to office 365. After a VERY slow move of our first mailbox which was successful. Our network is getting saturated with traffic. Bellow is a screen shot of our network usage and firewall SMTP traffic. Something is still sending from our Hub Transport server but i can't figure out what it is. Nothing is stuck in our Queues? Thanks in advance!

EDIT: This is also affecting incoming email, mainly larger attachments getting deferred for later delivery.
