IMAP only downloads a message when you click on it, and attachments aren’t automatically downloaded. This way you’re able to check your messages a lot more quickly than POP.
If the email app has difficulty adding your email account, it’s usually because the email account is set up for POP access. In this case, you need to go to your email provider and find out the name of their POP and SMTP server so you can enter the info into the email app. The info usually looks something like this:
- Incoming Mail (IMAP) Server: imap.<name of service>.com
- Incoming (POP) Server: pop.<name of service>.com
- Outgoing Mail (SMTP) Server: smtp.<name of service>.com
