Hello @fferraro87 ,

to use the repository you can either use the username “serial” and your subscription key as the password, or you can use the username and password from https://portal.kopano.com/. In both cases your subscription key has to be valid (e.g. not expired) and for the portal account at least one valid subscription has to be linked to the account.

thanks @fbartels
