In that case its OWA on O365. I thought that used exchange 2013. This is ultimately managed by the LEA. I just need to try and determine whether this is a local issue, a network issue or a Microsoft issue or a combination. Sorry I cant give you more info on this.

Yes, its definitely 365 on Exchange 2013 -

Been getting several schools reporting an issue that they are unable to send attachments using the 365 OWA. The device is connected to the internet as you can see from the taskbar. This is happening on more and more machines and is causing real problems. The machine is running win7 pro on a school domain (Server 2012) This issue has just started happening over the last couple of weeks. Has anyone got any ideas as to what may be causing this or how I could diagnose this further.
