Hi, I'm trying to build an automated induction process for my school. I've manage to create the flow needed to automatically send out emails to new staff after they have completed an induction form, followed by subsequent emails that have the training materials attached. When I test this out, I can't open any of the powerpoints. I can open them normally on my computer, but through this email thread I can't. I've tried opening powerpoint in safe mode but same message occurs...

I've tried downloading the powerpoint but no luck either.
Here is my flow as it stands...


Any help would be so gratefully received as it's driving me mad!! Thank you in advance 🙂
