I'm experiencing a very strange problem on of my client, they're using Exchange Server 2003 and Outllok 2003.
When someone responds to mail the characters of the mail become unreadable the same applies to their supplier that sends a pdf created using crystal report, in which case the pdf is illegible.
if the same mail are sent to an external email account (ex: google) everything works fine.
The problem is not on all the email and not by all the senders.
I also tried to see if throught Outlook Web Access the email cuold be readable, but I have the same problem.
