Truncated emails

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?

Yesterday I ran across a Microsoft forum that said Internet Explorer 11 was causing intermittent problems with Outlook on multiple versions.  They suggested to uninstall IE 11 and go back to IE10 and uncheck the auto update in IE (help, about IE, check box).  

Also they published a utility to help prevent an auto update.
Toolkit to Disable Automatic Delivery of Internet Explorer 11

We have uninstalled IE 11 and are waiting to see if this fixes the problem.

Hello
Test in Outlook Safe Mode if the problem still occurs

1. Click Start | Run.
2. In the Open box, type: "Outlook /safe" (without the quotation marks)
Notes: There is a space character between Outlook and the forward slash (/).
3. Click OK.

The above will tell us if an Outlook add-in is causing the problem. I don't know if it will untruncate existing messages, but it may tell us if any new messages are okay.

It isn't clear from your post, but I take it that incoming mail is okay? If so the issue is most likely the client, not the server.

Another way to check is to look at a user's mailbox through webmail, if you have it set up.

Additionally, you said you checked the server anti-virus, but also try and disable the client antivirus as a test.

Finally, check all logs along the path the email takes. Event viewers on the PC and server, firewall logs, anything that may be indicating there is a problem that is truncating the message. For the matter, check the firewall configuration and make sure it hasn't been putting a limit on message size.
