If your server runs cPanel, you may see the following error when trying to access Horde via webmail. You'll be able to log in now. However, this issue appears whenever you try to access a certain email account. This occurs most frequently during server migrations and rebuilds.

User  is not authorised for Mail

The Horde database may be damaged or require resetting, both of which could be the cause of the issue.

See if the database is damaged and fix it if it is.

The SQL query to verify the database is

mysqlcheck horde

The corrupt table will be highlighted. If so, please follow the below command to fix it. If the table horde alarms becomes corrupt, it will only be used as a point of reference. Substitute the correct name for the table.

myisamchk -r -o /var/lib/mysql/horde/horde_alarms.MYI

This ought to fix the problem. It's time to reset horde if the same notice keeps appearing. Ensure that you regularly back up your database.

mysqldump horde > horde.sql

The following command will reset the Horde.
