Hi

We have an in house SBS 2011 std. Is it possible to move some of the users to office 365 for both docs and mail (Outlook)? Can we have both working simultaneously such as using our company domain with both office 365 emails and in-house Exchange 2010? 

Thanks

Regards

I believe so, yes.

This forum is focused on the client software suite, rather than the hosted/online aspects of Office365.

You will find greater assistance for the hosted/online aspects, and deployment/migration, at the dedicated O365 community and forums:

If you have further question about this, I recommend you post the question to Office 365 forum.
