So I have a gmail account and a school account. I use POP3 in my gmail to download all e-mails from the school account.
Outlook connects to gmail using IMAP which gets e-mails from both accounts. I want to add an account so that if I receive an e-mail to the school account, I can reply to it using the school account. But if I add another account in Outlook, the only option is POP3 and it downloads all the e-mails from that account.
