The error about the deactivated link is due to your district IT blocking the link to go through. It is very common to have external emails scanned for links and the protection software to access the links to check for safety. I recommend reaching out to the IT who should be able to 'white list' emails from the PowerSchool domain. This would allow external emails to still have the one-time reset link available.
