Apple mail messages loading very slowly
My apple mail account is fine. However, my wife's account it takes ages for each mail to be downloaded from the server. It is slightly better on her iMac, but on iPhone, and iPad sometimes it can take between 30-60 seconds from each mail item to load up. It can't be the wifi as we are on the same network, and the iMac is ethernet. I've tried a different mail app, but it is the same problem, the body of the email is just taking ages to appear.
Any suggestions? Thanks
