Hello MS Community!
Running Exchange 2013 CU2 with all applicable patches. Server has been in production for 2 month now. Over the last couple of weeks Event ID 4023 started to appear in the Application Log.

Description:
Process w3wp.exe (AirSync) (PID=3388). The budget for user 'DOMAIN\username_HTC188c824b2995ba5de8ef4a3ef73ae_htcvigor' is locked out until 11/20/2013 6:20:12 PM. Max Burst: 240000, Recharge Rate: 360000, CutoffBalance: -600000
This is happening for iOS and Android users. I reviewed both the Global Throttling Policy and Default Throttling Policy. There are no other policies in place. Global Policy is read only and can't be modified. For Default policy I doubled the EasCutoffBalance, EasMaxBurst, EasRechargeRate. Restarted the Microsoft Exchange Throttling service. Still the same issue. Checking affected mailboxes with Get-MailBox shows no ThrottlingPolicy assigned, so default must be in effect. So there are 2 questions:
1) Why is it happening all of a sudden?
2) Why modifications to the policy make no difference?
Thanks!
