If you are asking if there is some sort of export function your phone might use. I am aware of nothing. Perhaps you might ask about import features on your android.

It really depends on how effective the Android app is at finding the correct settings when you enter your address and password. They will generally look for IMAP settings automatically, although POP or Exchange may be options, and all will probably work well for well-known mail providers such as gmail, aol, outlook.com etc. I've never investigated the relative ease of setup, having been satisfied with the Gmail and Outlook mail apps.

Both of you, thanx for the answers. it helps me do search in the right direction. Thanxs again!
