I just switched to Microsoft Exchange so we can send more emails... We use the SMTP option but it is giving us an error message saying we don't have permission to send emails on our emails behalf. Does anyone know how to fix this? I think it is because we are trying to us SSL Authentication and not the other T one. SiteLink didn't have an answer for me and I don't think Microsoft did either... So I'm hoping one of you guys have ran into this issue.. I've been working on this all week and need some help!
