This has been fixed with this update.

File: Two-factor authentication for logging on to WebAccess

With this release, a method for two-factor authentication (2FA) can be activated for the WebAccess, that in addition to the password of a user asks for a temporary one-time password. The user receives a one-time password through an authenticator app or a security token. In the future, the user will have to enter the one-time password, if 2FA is activated, each time you log on to WebAccess, after entering your login and password. This second level for checking the authenticity of the user eliminates the risk of guessed or spied passwords.

Notes

Kopano Groupware: Database conversion after update 7.1.6

The Kopano database is automatically converted for update 7.1.6 after the server is restarted. This process can, depending on the database size, take between half and several hours. In the dashboard this background task is visible as a job. The Kopano service is not available at the time of conversion. Before the update, make a complete backup of the data. When the conversion is complete, the Kopano service is restarted. Subsequently, further optimizations and schema changes are made. In this time the services Kopano and MySQL may not be stopped.
