My customer has a Exchange 2003 Server (SBS) using Outlook 2003 clients. My customer sends out newletters to current and former customers to the tune of 30K or so on a monthly basis. In the 2003 products, the way I understand it, there is a limit as to the overall size of an individual e-mail task that gets sent out. Such as: An e-mail sent to individuals from am Outlook contact list would allow fewer recipients than just sending to straight e-mail addresses due to the fact that the Outlook contacts add extra size to an e-mail sending task than does using e-mail address. My customer, can send his monthly e-mail to about 5000 recipients at a time just pasting the e-mail address in the Bcc: field. However if he uses Outlook Contacts, he can only send the same e-mail to 250-500 in one shot. This is my understading of the limitis in the 2003 products. Make sense?
My question is: Do these limits also exist in the 2007 Exchange/Outlook products or have they been in creased or eliminated?
