Seeing continous "Request length exceeds defined buffer size" alert.

Hi,

Actually, what i dont understand is that, end user is not sending any emails from his outlook client when this alert is triggered by ASM but when i run the PCAP in ASM device, i could see content legnth value as 1073741824). Need to understand why outlook is sending this value to my OWA service while in IDLE situation.

If this is outlook issue, i am seeing such behaviour in multiple outlook clients. Let me know how to address it. Currently we have allowed this traffic as we fear that this could lead to service outage. If we know actual issue , we can block at ASM level.

Kindly advise.
