When you are activating your user account for the first time, you might come across an l_Invalid Token message when you click the link which you need to use to activate your account.
This happens if your administrator clicks the "Resend invitation / password mail" button in Company Administration before you had the chance to activate your account.
In this case, you need to request a password reset mail from the login screen of the web client.
Company Administrators, please don't use the Resend invitation / password mail button for newly created users. An activation mail will be sent out automatically.
