What happens when you have no choice? If you’re using a provider that requires you setup your email account as a POP account, you must go through a bit of extra configuration. If you do that, you’ll never lose an email just because it was read. So, the ideal answer to the question is to always set up email accounts on all of your devices (and your desktop) as IMAP. IMAP also has the added benefit of being able to work with folders and subfolders - whereas POP cannot. IMAP, on the other hand, automatically leaves a copy on the server, so there’s no extra configuration needed. This is the default behavior and must be configured to actually leave a copy on the server. With a POP account, when your device downloads an email to read it, that email is removed from the server. IMAP: Automatically leaves mail on a server until you delete it.POP: Has to be configured to NOT delete mail from a server.Why, you ask? Without getting too deeply involved in the differences between POP and IMAP, there are only two things you need to understand (with regards to mobile devices and POP/IMAP): I’ll cut to the chase and say that POP accounts are not the best route. This question can be tricky, depending on the type of email service is involved.
