Thanks in advance for the help! Scenario Server 2008 running Exchange Server 2007 SP1 (twin Zeon quads with 8GB ram and loads of disks - resources are not an issue) Server has been running fine for two months - 100 users (we use messgaelabs to filter all our email for us) Last two weeks we ave started getting random emails (i.e. different senders and recipients to and from differnet domains - but not all from a sender or to a recipient - only happens with externally sent emails) These emails have a readable header and footer - BUT the rest is corrupted into what looks like chinese symbols in block for around 50-100 lines The same email sent to an account not in this server (my hotmail account- is in clear and comes up fine) Message labs deny all involvement and knowledge and say the tests they have done are proving it is either the client or the server at our end. 95% of clients are outlook 2003 on xp sp3 the rest mixture of xp sp2 with outlook 2002 or windows 2000 sp4 with outlook xp (2002) it doesnt seem to matter which client it s received on or viewed on - it even shows up in webmail The mails cant be viruses as message labs filter that out (i hope) - i have not changed the server (apart from important updates through windows update. All help gratefully received! Thanks Ed Baker sample below Subject: RE:

I have one person reporting this same issue receiving from one sender (comcast.net), but when the sender uses plain text the message is fine. There seems to be an issue with HTML, and I think it is on the sender's end. We are not having issues with other senders from comcast.net.

i have had the same problem crop up on a few computers in the past week. mainly outlook 2003, however, i have had one computer with the same problem sending from outlook 2007.if anyone has an explanation or a solution i would be very interested!removing all add-ins corrects the issue. i did try to work out which add-in was causing a problem, to no effect.also sending emails as plain text seems to correct the issue.neither solutions are conclusive or fix the problems, just workarounds!

We have been seeing similar corruption on a small % of our mail as it flows through Message Labs. Have a ticket open with Message Labs for a month or so. Had limited success finding a solution so far although getting users to remove any rich text or html from message footers seems to help. We are running Exchange 2003 on 8 x DL380 G5 Win2003 32bit R2 servers realying all external mail to Message Labs as a Smart Host.

Hi I am having the same problem with a new SBS 2008 server and exchange 2007 with outlook 2003 clients on XP Has anyone discovered a solution to this?

We are having this issue also, are there any fixes out there? I have been researching this endlessly. We are sending the emails from a 3rd party client we have coded and cannot code in the charset, exchange 2007 is defaulting it to Chinese.

I have the same issue, but mine is with emails I send. Exchange 2007/Windows 2008. SP1 (no rollup)Anyone found a resolution. I am planning to go to SP2 tonight with Rollup 1 post SP2 and see what happens.Tyler Barnes

We found the issue, but had to resolve it by removing a feature. We'd created a transport rule for all emails to have a footer. We removed this and seemed to resolve the issue. We didn't research it any further so I'm not sure what happened or how to correct it.

We've had reports of the same issue at a client of ours. In our case, the problem appears to be related to how the encoding is configured in Outlook. In 2007, SP1 changed the way Exchange handled MIME headers in the email ( http://support.microsoft.com/kb/946641. Changing the Non-MIME Character set option to UTF-8 resolved the issue. in 2007, this setting is in Exchange Management Console -> Organisation Configuration -> Hub Transport. Right click on Hub Transport and click "Default" option. Then udner "Character Sets" options, set the Non-MIME Character option to Unicode (UTF-8)
