I work at a school and we have a Spam filter policy activated in Exchange Online. We notice that sometimes some emails from parents are seen as bulk mail. By adding them to the allow list of the spam filter policy, all mails from that parent comes through. But I want to prevent this from happening ever again with any parent by adding all registered addresses of parents to the Spam filter policy Allow list. It looks like I hit a maximum of 1024 entries since I was trying to add over 2200 addresses.
How can I achieve the same in another way? Or can I raise the limit of the Allow list somehow?

Something else you can try is to add them to "bypass spam filtering" Transport rule, however there are limits there as well. Maybe change the default "bulk" action to quarantine, and then review the quarantine at regular intervals to release any parent's messages?
