Hybrid Exchange 2010 and Office 365

Dear Experts,

I have a single domain, a DC server and an Exchange 2010 server for about 18 users.  I am thinking of implementing a hybrid environment of Exchange 2010 on premise and Office 365.  The idea behind using Office 365 is as a failover should my on premise fail for some reasons.  I also wanted to utilize other features within Office 365 such as OneDrive, Skype for Business, and such.

I would like some help on how to get started, and what I need to look out for to be successful.  Thanks.

Hello,

It's more a project but maybe you could tell us more about your expertise on Office365 and Exchange environment.

Do you know the difference between different Office365 plans ? Did you have chose one of them ?

Here some prerequisities for an Hybrid deployment : https://technet.microsoft.com/en-us/library/hh534377(v=exchg.150).aspx

Let me know !

Hybrid doesnt give you failover/HA features, if anything it bring another failure domain. For such a small shop I'd definitely consider going to O365 and ditching the on-prem servers.

@François Peroux - I have touched on for about 3 days for Office 365 on a trial.. but didn't have time to really continue... and had hard time figuring out how to have the users signed in with our domain instead of Microsoft long address... so to sum up... no experience with Office 365 whatsoever.  I know my way around Exchange fairly well.  I picked E3 plan as it does offer other collaboration tools that we need such as Skype for business, OneDrive, conferencing, etc.

@Vasil Michev (MVP) - I have to keep this single on-premise server..

What you need to do is to configure the SSO with Office365 and your Active Directory (on-prem).

SSO means Single Sign-On. Your user will log into his windows session and automatically logged-in Office365.

You have a step-by-step procedure here : https://blogs.technet.microsoft.com/canitpro/2015/09/11/step-by-step-setting-up-ad-fs-and-enabling-single-sign-on-to-office-365/.

If you are using 2008, you have to download and install ADFS 2.0 (available here: Active Directory Federation Services 2.0 RTW).

Launch Windows Update after this install to have all the update regarding this installation.

I wouldn't recommend ADFS SSO for such a small company of 18 users--too many headaches and requirements to implement.  Instead, look at AAD Connect and password synchronization.
