What's changed: Created MS-700 Chapter 2 (domain: Teams environment, external collaboration and devices). External/guest access (External access federation vs guest access membership, SharePoint/OneDrive external sharing, shared channels Teams Connect, B2B direct connect, cross-tenant access, MTO) and Teams clients/devices (Teams Phone/resource account/devices licensing, configuration profiles, Microsoft Teams Rooms, firmware, device tags, remote sign-in, Teams for VDI).
2.2Teams clients and devices
Understand licensing for Teams Phone/resource accounts and devices, configuration profiles, Microsoft Teams Rooms, device firmware/tags, remote sign-in, and Teams for VDI.
For Teams devices, verify licensing, configure in bulk, and operate them organized. Phone and room devices each have requirements.
2.2.1Licensing and configuration profiles
A Teams Phone, a resource account (for auto attendants/call queues), and Teams devices (phones, panels, Teams Rooms) each have licensing requirements. Configuration profiles apply common settings to many devices at once (language, time zone, display). Manage device firmware updates to keep devices secure.
2.2.2Teams Rooms, tags, and VDI
Microsoft Teams Rooms are dedicated room devices; configure their account (resource mailbox) and system. Teams device tags are labels that group devices by location or purpose for bulk management/filtering (distinct from configuration profiles). New devices can be signed in remotely via remote sign-in. For virtual desktops, configure Teams for VDI to optimize media.
Cues: "apply common settings to many devices at once" = configuration profiles. "labels to group devices by location/purpose" = device tags. "dedicated room device (resource mailbox)" = Teams Rooms. "remotely sign in a new device" = remote sign-in. "optimize media on virtual desktops" = Teams for VDI. Auto attendants/call queues use a resource account.
Watch the mix-ups: (1) Configuration profiles (bulk common settings) vs device tags (grouping labels). (2) Teams Rooms (room device, resource mailbox) vs ordinary Teams phones. (3) A resource account is for auto attendants/call queues—different requirement from user licenses. (4) VDI is media-optimization configuration.
2.2.3Section summary
- Configuration profiles = bulk common settings; device tags = grouping labels by location/purpose
- Teams Rooms are room devices (resource mailbox); manage firmware updates
- Remote sign-in signs in new devices remotely; Teams for VDI optimizes virtual desktops
