replace de disign of you database to a 6.5 template. it should work
If the error message is correct, my guess is you are using COM from MS Access to create a backend Notes/Domino document, then using the Send method to send it. However, you are likely setting the first parameter of the Send call to TRUE. Thus it is trying to store the form in the message. Change it to FALSE and see if the error goes away. If you are connecting to the user’s mail file to create a document using the MEMO form, then using FALSE will not only work, it will not send a huge message unnecessarily.
