Similar to the troubleshooting step above, if you’re also having trouble with SSL on your outgoing SMTP server, you can try using TLS or STARTTLS, which allows for encrypted messages to be (optionally) sent over traditionally unencrypted ports.You’ll usually find the TLS toggle in the same place that you first enabled SSL. If your email client or device isn’t working with SSL enabled for your incoming IMAP server, try switching to TLS, a newer encryption protocol.Some email clients may not work with the configuration listed above, so if you’re still having connection issues after entering the server and port info, you can give the following troubleshooting steps a shot: Note that some email applications don’t specifically list “IMAP” as a valid account type you’ll usually find it listed under “More” or “Other Accounts.” Type or copy and paste the correct information into each field.

IMAP compatibility for many devices and apps can be determined directly in the email configuration menu itself - when creating a a new account, an app or device that has a field for IMAP servers or addresses is generally a safe bet - but you can always verify compatibility with a quick Google search or a trip to the manufacturer’s website. Most consumer devices and third party email apps support the IMAP standard, but taking a few moments to verify compatibility before you begin can save you some headaches if things don’t work later on. ICloud email relies on the IMAP and SMTP protocols for sending and receiving email, so the first thing you’ll need to check is your device or software compatibility. Here are the iCloud email settings you’ll need to know to get started. While some third party devices and applications support automatic setup for iCloud email, many do not, and they require the user to manually configure iCloud email settings. But many users, by choice or otherwise, interact with a variety of devices and platforms each day, such as a Windows PC at work or an Android tablet at home. ICloud members who exclusively use Apple products don’t have to worry about setting up or configuring their iCloud email when they move to a new device Apple handles the configuration automatically in the background, with users only needing to supply their iCloud email address and password.
