We have a mail merge with 500 clients in SalesCQ. It takes between 45-75 seconds to create each email, the Word template file is 165k. We have created a completely blank template with the same results. We are using Windows XP with Outlook Express as our local email client. Email is hosted. Same result with no anti-virus installed on the workstation. When emailing from A/R or O/E emails work almost instantaniously.

When we merge the 500 customers to a Word letter, the application completes within a few minutes for all the customers.
