Horde Webmail will be removed from cPanel in the coming months, upon upgrade to version 108 or later of cPanel. This is due to Horde not supporting PHP 8, while PHP 7 reaches its end of life in November 2022. Additionally, critical security vulnerabilities were discovered in Horde over the past year which required us to disable Horde for several weeks until security patches were released.
cPanel will be focusing on RoundCube Webmail going forward and are developing tools that will migrate Horde calendar and contact data to RoundCube upon upgrade to cPanel v108 or later.
If you are currently a Horde Webmail user, we recommend switching to RoundCube the next time you log into Webmail.
