Hello Experts,<br />
I would like to know if the following is possible: <br />
<br />
<b>On-Site Exchange 2013 </b><br />
<b><br />
O365 Exchange Online</b><br />
<br />
I would like to have the on-site exchange server providing mail services to mobile users on their phones<br />
<br />
and<br />
<br />
Have O365 for the reset of the business staff.<br />
<br />
I need to split them due to custom web applications etc.<br />
<br />
Would i need to have O365 licences for the on-site exchange, that already has a licence? I was planning on performing a Hybrid &nbsp;deployment. <br />
<br />
Many Thanks,
</div>

Mobile web development, also known as responsive web design, is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones). A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries.
