E-mails updating on Ipad2
I recently bought an iPad2, and have successfully set up to collect e-mails from my Yahoo account when I'm on the road. I also access these e-mails via other PC's and on my main PC this is set up to download the e-mail from the serve into outlook.
However, after the e-mails have been downloaded from the server, they still appear on the iPad. Is there a feature so that the iPad deletes these e-mails after they have been deleted from the server, or do I have to do this manually?
