Hi, I have a customer who upgraded 4 of his Snow Leopard based iMacs and Macbooks to OS Lion. All of the programs except for Mail are working. The mail app crashes 3-4 times per day on all but one computer and we can't figure out why. I've attached copies of crash logs from two of the computers.
Any ideas? I searched all over and found a lot of people are having this issue with no clear answer.
