There are other 3rd party solutions that let you backup and retain your data for as long as you want.

If you need to filter everything centrally no matter the device the doing it on a router or firewall would be the answer, you are not dependent on any local configuration or software. You could swap out the router for a DrayTek with a web filtering subscription, this would be pretty low cost and you would be able to demonstrate that your specifically filtering on Safeguarding sensitive areas, I dont know unlike schools what the library's obligations regarding Safeguarding. There is a link to the DrayTek Webfiltering here Web Content Filtering

As above I would not create a 2nd Office 365 tenant but have all the domains you want verified within a single Office 365 login plus if in the future you want to start using things like Microsoft Classroom or OneNote for Classroom its easier when the teachers and students are in the same tenant when setting up classes etc

It depends how the migration is being done - if this is a hybrid environment then it will be possible, see this information from TechNet: Support for cross-premises mailbox permissions Exchange hybrid deployments support the use of the Full Access mailbox permission between mailboxes located in an on-premises Exchange organization and mailboxes located in Office 365. A mailbox on an on-premises Exchange server can be granted the Full Access permission to an Office 365 mailbox, and vice versa. For example, an Office 365 mailbox can be granted the Full Access permission to an on-premises shared mailbox. Users need to open the mailbox using the Outlook desktop client; cross-premises mailbox permissions aren't supported in Outlook on the web. We don’t, however, support the use of the Send-As, Receive-As, or Send on behalf of mailbox permissions in hybrid deployments between on-premises Exchange and Office 365 organizations. We also don't support delegating permissions to a mailbox or individual folders using the Outlook client. These permissions are only available when both the mailbox granting the permissions, and the mailbox receiving the permissions, are in the same organization. Any mailboxes that receive these permissions from another mailbox need to be moved at the same time as that mailbox. If a mailbox receives permissions from multiple mailboxes, that mailbox, and all of the mailboxes granting permissions to it, need to be moved at the same time. In addition to these permissions, the Auto Mapping feature is also unsupported when used between mailboxes in the on-premises Exchange and Office 365 organizations.

You got the specific error message she is getting? Also you should be able to filter on the firewall for any denys to the BT Servers.

Microsoft has launched a Cloud PBX which is an add on to your Office 365 subscription, we are looking to install it here in the next few weeks. I will post how it goes and what our impression is.

Team sites would be typical solution for this, be aware of the 5000 item limit in SharePoint Online, you can store more than 5000 items but you have to plan for it.

How are you managing your Office 365 accounts, are they AD sync'd or cloud accounts?

This should be possible, you could create one tenant with multiple domains for each school. What resources do you want to share? How are you managing your office 365 accounts, is this sync'd with AD or are they just cloud accounts?

A+,N+ and then CCNA. Try and source some cheap layer 3 managed switches as well, then you can lab up some scenarios.

That's the sort of thing that really hacks me off, people are in business to make money, I understand that but it doesn't mean that anything goes. We went into one school that specialises in caring for autistic children, a large IT provider went in over sold to them, spent a huge amount of their money and then didn't finish the job, I struggle to understand how people can walk round a school like that and only be focused on closing a deal, but hey maybe that's just me. Glad you got a handle on the issue and no long term damage was done.

Is this an iSCSI San with multi-pathing? We had an issue on just one switch and the whole thing failed. Agree with sister_annex, network looks a likely candidate. In the iSCSI config you can verify the paths and rebuild them from memory.

We have seen a few schools have issues with the way Windows 10 gets updates, their are a few new options in the settings which we had to disable. YOu can do this through group policy using the WIndows 10 ADM and it's under delivery optimization settings. I have included a screen of the setting on the PC.

Good read, thanks for the link.

We've worked with both but we are seeing a shift to Office 365 now with the schools we work with, a few of them have really got going with OneNote for Classrooms and the Preview of Microsoft Classroom and the feedback is very positive. I think it's a win/win but I would favour Office 365 for more reasons that I can explain here.
