I have the oddest thing occur, emails from ONE domain are being sometimes stripped of body, my infrastructure is 2 CAS/HUB, 2 DB, 2 edges with Forefront on them. My forefront is configured with Content Filtering Enabled but this domain is WHITELISTED on the allowed domains tab. Below are the interesting part of headers: X-MS-Exchange-Organization-PRD: sample.com Received-SPF: SoftFail (MYEDGESERVER.local.edge: domain of transitioning user@sample.com discourages use of XXX.XXX.XXX.XXX as permitted sender)

Just to isolate if it's a malformed header alignment, see if you can forward one of those messages to an outside account ie. your hotmail and see if the message body shows up. Also check if OWA renders it. I doubt it's forefront.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I have done the exact, the email is still shows EMPTY in the outside (google.com) and empty on OWA.Vladimir

What third party outlook plug ins if any? Archiving, AV?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I have a cloud service APPRIVER, but I was able to rule the stripping out, by troubleshooting with them, they were getting emails with body, but when it went thru my exchange, it stripped it. No AV on any exchange boxes, no archiving either. No plug ins on outlook either, AV= Microsoft essentials.Vladimir

go ahead and enable pipeline tracing it will at what point it still has body content whether before or after it hits the mailbox. http://technet.microsoft.com/en-us/library/bb125198(EXCHG.80).aspxJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

The issue was with Oranization Configuration--> Hub Transport -->Transport Rule. Due to the fact I have 2 exactly identical CAS/HUBT (failovers), they must have identical transport rules, otherwise you will get intermittent issues like I did. Once the Transport rules were identical, all is flowing as designed. Thank you all for pointing me in the right direction. Vladimir
