I want to create a student homework update reminder in outlook.

I have all the pupils in each class in distribution groups (alot of lists) - this is automatically updated each night.

Ideally I want teachers to send an invite to the dist group and an entry in Outlook be created for this event.
- They should not be able to delete this event
- It should auto accept as well.

Any thoughts would be appriciated.

Thanks.

Steve
