Hi There I have a problem with exchange 2007 My users aresending out large mails. 2mb each in total. What is happening is that when users send out 2mb x 40mb= 80mb. The mails comesback and says that it was delayed. but the receipiant received the same message about 10 times. so all in all there is about 800mb in total going out. I checked for viruses and spam but can't seem to find anything. We do have a slow connection though. 512kb down and 256kb up. please help Taz
