Not for channel messages — and this distinction matters. The Cisco Webex app for Microsoft Teams covers Webex meeting starts and Webex Calling. It does not route Teams channel messages to Webex spaces, and Webex space messages do not appear in Teams channels.
This guide explains the exact scope of the Webex Teams integration, why channel messaging is not included, and how to bridge Teams and Webex bidirectionally.
The Cisco Webex App for Teams: What It Does vs. What It Doesn't
The Cisco Webex app in the Microsoft Teams App Store handles Webex meeting starts, scheduling, and Webex Calling (telephony). It does not route Teams channel messages to Webex spaces or route Webex space messages to Teams channels. Even with the Webex app installed, Teams and Webex are completely siloed for messaging. If you need Teams↔Webex channel messaging, a dedicated bridge such as SyncRivo is required.

Who Needs a Teams ↔ Webex Bridge
M&A: Teams org acquires Cisco-standardized company
A Microsoft 365 / Teams-standardized enterprise acquires a company where Webex is the primary messaging and telephony platform. Both organizations need to communicate during the integration period. SyncRivo bridges both from day one — channel messages flow between Teams and Webex while the Webex app continues to handle meetings and calling.
Government/defense: FedRAMP Webex + Teams contractors
U.S. government agencies using Webex FedRAMP-authorized environments need to collaborate with Microsoft 365 contractors or other government entities on Teams. SyncRivo is not FedRAMP authorized; agencies should confirm their authorization requirements before bridging.
Internal split: Cisco infrastructure teams on Webex
Organizations where corporate and collaboration teams are on Teams under Microsoft 365 agreements, while Cisco networking, infrastructure, or security teams use Webex under Cisco ELAs. SyncRivo bridges the internal platform split without guest accounts or platform migration.
Enterprise client/vendor relationships
Large Cisco-standardized enterprises (financial institutions, telecoms, government contractors) frequently need to collaborate with Microsoft 365 technology partners. Per-relationship channel bridges keep communication in each party's native platform without requiring either side to create guest accounts.
Bridge Teams and Webex with SyncRivo
SyncRivo connects to the Microsoft Graph API and the Cisco Webex APIs simultaneously. Messages route bidirectionally between Teams channels and Webex spaces in real time. The channel message bridge runs alongside the Cisco Webex Teams app — meetings and Calling route through Cisco's infrastructure, channel messages route through SyncRivo.
SyncRivo bridges five chat platforms — Teams, Slack, Webex, Google Chat, and Zoom — with direct API connections and no hub intermediary. Emoji reactions are not synced to or from Webex.
How to Bridge Teams and Webex
Authorize Microsoft Teams via Graph API admin consent
In SyncRivo, click "Add Platform" → Microsoft Teams. Sign in with your Microsoft 365 Global Administrator account and grant the required Graph API permissions.
Authorize Cisco Webex via OAuth2
Click "Add Platform" → Webex. Authorize SyncRivo via Webex OAuth2 — SyncRivo registers as a Webex bot with Rooms, Messages, and Webhooks scopes.
Map Teams channels to Webex spaces
Use the SyncRivo dashboard to pair Teams channels with Webex spaces. Configure sync direction and message types to sync — text, threads, files.
Configure identity resolution
SyncRivo matches users by email across Teams and Webex. Messages can show the original sender's name and avatar where the destination platform allows it.
Test and go live
Send a test message from Teams and verify it appears in the Webex space. Reply from Webex and confirm the reply appears in the Teams thread. Enable all mapped bridges.
