I found the answer in the smtp message size settings of IIS. &nbsp; The properties in the messages tab folder was set to 2048. &nbsp;Is 4096 a standard size? I doubled it.

jmorin1: sorry, but my comment was not an answer, just a few hints which could be helpful. And then, the Exchange 5.5 menus are wonderful to get lost in when searching for some settings...<br />
Anyway, thank you too, very much so.<br />

I have exchange on 5.5 and a smtp server performing filtering on a Win Server 2003. &nbsp;I use a third party application that I could not find a setting that restricts the size of in/outbound mail. Might I find this in the smtp module of IIS for server 2003? Or is this restriction being done on the Exchange server? &nbsp;<br />

Thanks,<br />

Exchange 5.5 Sending and Receiving size restrictions.

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
