So is there not any other way I can speed that up?

Also, this is off my own topic, but I dont want to keep creating new topics.

I love the autofill function in outlook, however, it has a max of 1000 names before it starts culling them. I sent a mail merge last week with about a 1000 names, this just messed up everything, the normal people I email now I have to go back and find their email addresses. Is there anyway to increase the size?

Thanks
