Question

• What happens to existing Horde instances, and do users need to manually switch to another webmail client like
  Roundcube to maintain webmail access?

Answer
As of April 2025 (Plesk Obsidian version 18.0.69), Horde webmail is no longer installable or supported in Plesk, still,
existing Horde installations are not automatically uninstalled and may still function, though their reliability is not
guaranteed.

Users with existing Horde instances can continue using them at their own risk and no automatic migration to another
webmail client (e.g., Roundcube) will occur.
