Microsoft recently updated the New Office Visio Stencil to version 121412 (previously it was 112012).
This stencil contains more than 300 icons to help you create visual representations of Microsoft Office or Microsoft Office 365 deployments including Microsoft Exchange Server 2013, Microsoft Lync Server 2013, and Microsoft SharePoint Server 2013.
Creating visual representations of your Microsoft Office and Office 365 architectures, including Microsoft Exchange, SharePoint, and Lync is a helpful way to communicate your deployment. This Visio stencil provides more than 300 icons -- many depicting servers, server roles, services and applications -- that you can use in architecture diagrams, charts, and posters. These icons are primarily centered around deployments of Microsoft Exchange Server 2013, Microsoft Lync Server 2013, and Microsoft SharePoint Server 2013 as well as hybrid Office 365 deployments of aforementioned technologies.
