Here is my issue,
I am running an exchange server 2003 environment. Everyone on my domain has Microsoft office 2003. Within the last couple of weeks we have noticed that, for some reason, emails are being truncated. When I look at the sent box for the end users the email is truncated there too... I have checked the antivirus, on the server side, which controls the what the client side looks at and scans and the email protection is off. I have checked our firewalls and there is no SMTP filtering. there are no viruses on any of the machines that are experiencing the issues. ( I have run scans on all of them). Any ideas on what else to check? I have changed the email from HTML to plain text and that has seemed to stop the issue but there are some users who need the HTML for their signatures.
Any ideas on what else to check?
