Sending automated emails through Office 365 via Java Mail app, the address is getting blocked in Exchange.  I then need to go to Action Center and unblock the account before I can move forward.

Sending roughly 400 email in the early AM and it gets about 300 before is sending starts failing.

What can I do to stop this account/email address from getting blocked on a daily basis?
