The following error occurs when trying to send emails from Horde Webmail:
This request cannot be completed because the link you followed or the form you submitted was only valid for 0 minutes. Please try again now.


The issue may be caused by a missing configuration parameter in a Horde configuration file. The issue may occur if you have modified the Horde configuration or if Horde's configuration was modified via the installation or upgrade of certain packages.


Open the %plesk_vhosts%\webmail\horde\imp\config\config.php file and make sure that this parameter’s value is greater than or equal to 1800:
$conf['server']['token_lifetime'] = 1800;

This parameter defines the global session lifetime for message composition in Horde.
If the parameter is not defined, its default value is 0, which means that you have 0 seconds to submit a message. So, the session will expire right after you click the "New message" button.
