Sorry if I reapeat anything that has been said before however we have just finished another school migration to live@edu and have come across a number of gotchas that you may want to be aware of:
The mere fact you have to setup a trusted internal site with a certificate provided by the live@edu team in order to have SSO running is a lot of work for very little benefit, and you will end up with two different URLs for accessing thier email (internal/external)
FIM / PCNS / OLSync
This has got to be one of the hardest things to setup once you have it working back away and leave it alone - Do a bare metal recovery backup on this box so you can recover easily should it fail.
First Time Sync
When doing your sync for the first time the accounts will be created but the passwords will not, you will need to go through a complete password change cycle in order for PCNS to inform FIM to the inform OLSync
If you plan to use a different domain on live@edu for your email instead of the one used internally then you will need to add your external domain to your AD Domains & Trusts as a UPN Suffix and then update all of your internal user account to use the new suffix otherwise your OLSync will fail with a very unhelpfull message.
I am currently doing all of our migration documentation for this school we just completed so as I go through this I will update this thread with more pearls of wisdom.
In the meatime any questions fire away :)
The new technologies (ADFS, DirSync, etc.) only apply to Office 365 for education which is not yet widely available.
"If it ain't broke, don't fixt it" is a good way to view your current ILM installation - unless there's a burning desire to rebuild it all under FIM, I'd leave it alone for now! :)
If time is short and account syncing, integrated passwords aren't that essential you can copy mailboxes to live@edu without OLsync etc. via a Staged Migration where you create the users in live@edu via a CSV, then use the ECP to migrate them via a similar CSV. But you need that Exchange 2007 system to be nicely configured for Outlook Anywhere (RCP/HTTP) with a cert from a recognised CA and you need an account that's got Full Access to all your source Exchange 2007 mailboxes. ["recognised" roughly means any CA that MS have in the Windows cert store by default or via their root cert updates]
Disclaimer: There is a live@edu Service Update in progress that promises a new improved migration dashboard that might turn up sometime (ETAs for updates are not very predicatable). There is no reason to think the new features will break what has been possible to date, but until I've used it...
I've just recently setup FIM, PCNS and SSO for live@edu
At the start it might seem hard to setup, but actually it's rather easy and there is lots of good documentation to follow. I'm happy to try help if you have any questions.
I find SSO very useful, especially for students. Since all email accounts are created from AD using FIM and olsync everyone's email account name is NetworkLoginUsername@domain.whatever
Very easy for all to remember when using email outside of school, plus having PCNS to sync the passwords makes it even easier. It’s especially good for students as it stops them 'pretending' they've forgot their school email and password to get out of lessons.
You can add dns entries so Outlook auto discovers the settings when setting up an Outlook profile. This is good for staff that have laptops because they can easily setup outlook themselves and use the same application in and outside of school.
I don't see any need to map drives if they have a skydrive link. Surely thats the point of it?
Its an exciting future anyway :)
SkyDrive integration is one of Microsoft's trump cards over Google, tbh it could've been done with Windows 7 but it's most likely been held back to give 8 a killer feature
You can also just map a drive letter to your skydrive
Have a look at this!
@jamesbmarshall it needs full blown SQL server?
