Sorry, I think I must not be clearly communicating what I want to do.
I changed the email directory structure on my computer. Many of the changes were reflected back to the server automatically so I assumed all would be. Now I have more that one device I find that was not the case.
I want to have the same structure on all devices and to be able to access all my emails on all devices so that if I move an email to a subfolder on one device it is moved there on all devices. To do that I assume I would need to somehow reflect the structure and email content from my computer back onto the server. Is there any way of doing this?
