POP3 vs. IMAP

POP3: All emails are to be downloaded again if used by another desktop PC for checking the email.May leads to confusion if used for checking email in office and at home pc.Attachments will be down loaded into desktop while the ‘check new email’ process is in progress.Mailboxes can be created only on desktop and one mail box exists on the server.



IMAP: There is no need for downloading all email while using another desktop PC for checking email.Unread mail identification is easier. Message downloading is possible only when opened for display from its contents. Multiple mailboxes creation is possible on the desktop PC and also on the server.
