On Business Central Cloud when customers want to delete account that is no longer used the message that occurs: "The user ABC_TEST_ROLLEN cannot be deleted because the user has been logged on to the system. To deactivate a user, set the user's state to 'Disabled'." is not customer friendly enough. So the customer thing that there is something is wrong.

For this reason I would like to suggest the following message.:

"The user ABC_TEST_ROLLEN cannot be deleted from the system due to technical reasons. Users can only be deactivated. In other to do so, set the user's state on the user card to 'Disabled "
