POP and IMAP settings for Exchange-based email

Some businesses and schools use Exchange-based email, but they don't use Office 365 for business. This is sometimes the case for corporations or schools that have an IT department to manage their own Exchange Server. In that case, you have a Microsoft Exchange account, not an Office 365 account. What is a Microsoft Exchange account?

Tip: To get your Exchange server settings, ask the person who gave you the email account. You need the settings so you can add your email account to your iPhone, Android device, or computer. It's standard practice for them to provide you with this information.

If you have access to Outlook on the web, you can try the following steps to find the POP or IMAP settings for your Exchange-based email account.

If you can't ask the person who gave you the Exchange email account for your server settings, you can try to find your IMAP and POP settings by using Outlook on the web. Try signing in using the email address and password that was given to you for your Exchange email account.
