Pat, there are two ways to read that request. I think you read too much into it.
@Rashid, there is no built-in mechanism to, in a single operation, include EVERY mail address in a table. It has to be programmed. You can do multi-user send operations but it requires you to write a code loop to step through a recordset and pick out one user at a time to concatenate the addresses. You would do this BEFORE you send the message.
The relevant part of preparing to send a message is to load a "To" field in the message header. This field can hold more than one address. Note that there can be limits to the number of addresses you can load based on string size limits that depend on your mail sender program.
In your recordset loop, you would extract each targeted user address followed by a semi-colon ( ; ) and concatenate it into the TO header field. This assumes you are doing this with a standard SMTP-based sender such as Outlook or CDO. Once you have finished the loop, you can then send out your message.
Take a look at what theDBguy offered in his code snippet as a possible example.
