It is not recommended to check all of your email accounts at once in Horde because of compatibility reasons. Before, you might have been able to do that by logging in Horde with your cPanel username.
However, this option is not officially supported and we recommend checking each mailbox separately.
Setting up your email is easy when you have the right host by your side. If you need a reliable partner to help you resolve email issues and provide expert support, check out our email hosting services.
