I'm running Outlook 2003 and XP Home. I've created a mail merge from word to send about 1000 emails. Merge goes well and puts all into the outbox, then Outlook only lets 16 go at a time before coming up with the message that there is too much traffic from this address. I've checked with O2 (my ISP) and they say that they won't & don't block emails. Does anyone know of a "work round" for this problem. Previously I've had no problems with this sort of quantity. If I click on the outbox the list of emails waiting to go is there but they are all just scrolling around continuously.
