hybrid exchange365

Can anyone provide any basics in terms of office/exchange365 "hybrid" approach. Does it mean half your mailboxes are in the cloud and half are hosted on an exchange server in your environment? If so why do people go for a hybrid approach, and not all in the cloud, or all on local servers?

Also if migrating to exchange365 cloud mailboxes, do you as a client have any control over mailbox/security policies etc, if so what kinds of configurations will MS discuss with you for your 365 deployment?

Hi,

The cloud servers are cheaper, it if possible to migrate low usage users to Cloud storage while heavy users can use on-premise Exchange Servers, also there are cases of legal jurisdiction of data for foreign companies, some countries do not allow the data to be hosted outside of the country's borders (Australia for example), In this case, online services like Exchange Online Archiving can be used with a hybrid deployment, users can access their own email archives from their Inbox, while not having to store the archive on-premise.

PowerShell commands can also be mirrored to online servers

Hybrid can also be used as an intermediate step to decommissioning an on-premise Exchange Server and vice versa.

You are not limited to 1/2 here and 1/2 there, there are many ways it can be setup.

A hybrid Office 365 solution means that you spread your Exchange Organisation over both your on-premise Exchange servers and the cloud environment. One advantage is that you get the best of both sides such as a Management Console. You can make use of the scalability and high availability of Office 365 for critical mailboxes and use you on-premise Exchange for less important mailboxes or archiving and backup purposes.
Another advantage is that you can transparently migrate your mailboxes without further configuration on the client side.
