Thanks very much - I appreciate the response.
The support desk don't want us messing with the filtering levels at school level - I tried it through SUMS as far as user levels go, that didn't do much.
I do know that Derby City are about to run a field trial with Office 365 and Google Apps at "selected" schools - Microsoft I also know are involved with this.
I'll look at the EMBC forum tomorrow and see what turns up, thanks again.
Punching outbound holes through proxys/firewalls for things like this can be a complete PITA - the MS lists/ranges just for Live@Edu are rather big and they have been know to change. Office365 will add to that, especially Lync which might be problematic. I think it's best, in fact it's probably necessary, for it to be tackled centrally by some rocket scientist at the [RBC|Whatever] rather than have folk doing it at the school level.
Thanks for the responses re Google Apps migration to Office365, I will go off and have a good look at those options.
I can understand that Google apps might not be popular for those who don't like change, especially after they had to go through it once with office 2003->2007. If the change is badly managed, without any training you will be asking for trouble.
Just got my email inviting me to upgrade to 365, wohoo!!!!!! :)
A link to the Google Apps Market place.
What you see is what you get with live@ and 365 and they are very good but it was not until we had fully used the Google system for a while that you realise how much is hidden away and not obvious. Take this in to account when doing a quick test to see which product you want.
According to Office 365 Vs Hosted Exchange: The 5 Biggest Differences | Techno Lovers an account is limited to sending 30 messages per minute. Does this mean we wouldn't be able to send the same email to all staff (140ish)?
No, that is the max number of separate messages sent from a mail client in a minute. In practice you'd address that email to some "All Staff" distribution group - it's just one message.
Emailing parents who are outside of the office 365 system is not the same as emailing a disitribution group containing accounts that reside within it.
For all staff we use a dynamic distribution list that emails everyone who's org is set to the academy.
If you were to send a mail to 1,500 parent addresses then in principle you can't send another mail from that account to anyone for 24 hours - the recipient rate limit
