Hi. I have my mail account set up on my MacBook Pro, iPhone and iPad. When I open the account on one device and delete unwanted emails this does not synchronise with my other devices when I open the mail account on a different device. This means I have to continually delete the same items on each device. Please can you help and advise how to set up my account to allow synchronisation across all my devices.
The features you desire require an iMap mail Server. Most ISPs provide only pop by default.
