I am being really thick here and struggling to get started. Once I get going I'll be on my way, but at the moment I can't spot an obvious route in to get some momentum (and motivation) going.
How do I test a user without changing DNS about? Do I need to use an alternate domain (I have one to hand anyway) or can I use the .sch.uk address? The staged migration document seems to say that email gets forwarded on from Exchange for now. Presumably then when I've moved everyone over, I update the DNS, and cut the Exchange box out of the picture?
Do I need to create the user account on Office 365 before the staged migration or is this done by DirSync? How do I configure Outlook to point to 365 for the email - is there a *.prf file or do I have to configure autodiscover on my internal DNS?
/feeling very stupid in the heat
I have Outlook Anywhere set up anyway, which is something at least!
Also - DirSync - does it want installing on a DC?
Documentations advises it not to be installed on a DC.
Prepare for directory synchronization
I'm also looking to do the same as you and keep getting lost as I don't want to break my existing exchange.
Bit of a necro, but I've just picked this job up again and it seems silly creating a whole new thread just to document my ongoing idiocy.
I've got a handle on what I'm doing and where I'm going now, I think - dirsync is working (without breaking my SCCM install this time, seriously, it would be lovely if the dirsync installer could at least check if I had SQL Server installed already and ask if I wanted to use that instead of assuming I knew to launch from the command line with a flag. It seemed like such an obvious question for an installer to ask I didn't even think to read up first :() and I've got a few sets of instructions on doing a staged migration, so I'm happy there.
Questions I have now are operational, really, as I'm still not commited to this path over Exchange 2013 onsite:
* Can I get access to other user's mailboxes without just resetting their password? Obviously important when dealing with children.
* Can I run cmdlets to search & remove messages from all mailboxes, as I can now with 2007? It doesn't come up often but it has covered backsides in the past and it'd be very useful to have this still (not a deal breaker, though)
* How do backups work if a user accidentally deletes an email? Does O365 store a certain backup range automatically? And, in all honesty, I need to know if we as schools are expected to retain this data for a set amount of time, and if so how does O365 jive with that?
yes, yes, yes - Message and Recipient Limits
