I switched from Entourage 2004 to Outlook 2011 and can no longer send mass emails. My outgoing mail server says there is no limit on my account and I never had a problem with mass emails before the switch. I tried switching ports, outgoing mail servers, but since the problem only started when I switched to Outlook, it seems there may be a setting or a workflow I am not aware of. I send out a newsletter every 2 weeks to 2500 recipients and can only send in batches of 25 at a time.
Help!
