A customer has installed Exchange 2010 and is in process of migrating mailboxes from 2003 exchange server to 2010 but the process is taking it's time. in the meantime, users who are still on an exchange 2003 server have an issue when they use OWA. If they log into OWA and send an email, it is received in chinese. I have seen KB article,http://support.microsoft.com/kb/969129, but it hasn't resolved the issue. Can anyone offer any assistance? The IT manager wants a fix in place now rather than wait for migration to complete which could take a while. Thanks in advance. mark

Hi, I'd like to clarify the issue with you first. If they log into OWA and send an email, it is received in chinese. Please verify if the issue would occur when owa 2003 user send email to internal 2003 users and 2010 users. Please verify if the issue would occur when 2003 user send email via outlook to internal 2003 users and 2010 users. Please verify the issue when you remove the disclaimer. What is the version of your Exchange 2010?With sp2? What does your disclaimer look like? Besides, please have a look at the article below: An e-mail message is corrupted after the Disclaimer rule is enabled on an Exchange Server 2007 or 2010 server http://support.microsoft.com/kb/935489 Xiu Zhang TechNet Community Support

Thanks for the response. I'd done most of those tests already and it was definitely 2003 users using OWA to send emails. I've taken a look at that KB article and that is the issue being experienced. I've downloaded the hotfix and I'm just waiting to be allowed to apply it. Once done, I test again & let you know how I got on. Regards Mark

Unfortunately the hotfix did not work. Users still see chinese characters when sending external emails via OWA. There are 3 back-end exchange 2003 servers & 1 front-end exchange 2003 server. Mailboxes still on 2003 servers are accessed via OWA using legacy.domainName.com I applied the hotfix to the front-end server, should I be applying it to all 2003 servers? It doesn't state that in the KB article though. Regards Mark

Hi, I recommend you to apply the hotfix to all the Exchange 2003 servers. Note: We need to reboot the server after we install the hotfix, so please try to install the hotfix on non-business hour.Xiu Zhang TechNet Community Support
