Hello Everyone,since the corporate exchange server has been changed to exchange 2007, we startedgetting scrambled emails through oil local exchange 2003, this applies only for attendance email notification form Calendar. scrambled means unable to view email because content is in base64. do you have any ideas how to fix it? Thank you in advance for help.

I have not heard of this before. What antivirus is installed on both sides? Mike Crowley A+, Network+, Security+, MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator Read my 2 on the Psychology of a TechNet Forum Thread!

Are you on latest rollups for Exchange 2007 sp RU9. There has been several fixes regarding encoding. Also can you paste a sample of your "scrambled" message?James Chong (MVP) MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Can you temporarily disable the McAfee scanning on both sides to see if the issue persists? Mike Crowley A+, Network+, Security+, MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

Can you temporarily disable the McAfee scanning on both sides to see if the issue persists? Mike Crowley A+, Network+, Security+, MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator Unfortunately, I don't have permissions on corp mail server.do you think this is related to antivirus ?we get this problem after corp mail server migrated to exchange 2007

I'm not saying that is definitly related, just a reasonable troubleshooting step. Antivirus has the potential to cause these types of problems.James also asked about your patch level.
