Hi, in case anyone is interested. I have now (via New User for EMBC portal - including email address | ICT Services ) got an account on (what I believe to be!) the EMBC / Notts portals - with OWA as well!
The Notts "Gateway" thing that I log into has "My Site" and "My LA" sections. The My LA section takes you to https://portal.notts.embc.uk.com , and there doesn't appear to be any / much activity on there at all.
The My Site (Sharepoint) section is detailed here for the (more attractive) Leics version.
I suspect it will be helpful for teacher colleagues who haven't yet managed to identify alternative (already existing) ways of providing this functionality.
The calendar only works with OE >6.
(The address book is filled with what appears to be the imported/migrated Mirapoint email orphaned accounts, including what appear to be pupil accounts for entire classes of children with full names from named schools.)
I can half remember from the migration briefing that the WIRED license was renewed for only another year so presumably there will have to be some movement with this.
