Ex2010 Hybrid to O365 mail flow delay

Hi,

Recently migrate the exchange to office 356. Unfortunately we are facing mail flow delay issue from on-premise ex2003 to Hybrid server ex2010. So I disabled 2 settings to make the mail flow from ex2003 to 2010. (Tarpitting and MaxAcknowledgementDelay).

Now the problem come, after disable this 2 settings. The mail flow now stuck at hybrid 2010 to o365. Anyone facing the same issue?

Regards,

Wayne
