How to Bridge Microsoft Teams and Cisco Webex(2026 Step-by-Step Guide)

No. Microsoft Teams and Cisco Webex are closed enterprise platforms with no built-in messaging bridge. Teams uses the Microsoft Graph API and Webex uses the Cisco Webex REST API — they have separate authentication, separate message stores, and no federation standard between them. SyncRivo connects both APIs to route messages bidirectionally in real time, so Teams users can communicate with Webex users without guest accounts, email forwarding, or platform switching.

A Teams Administrator or Global Administrator must grant tenant-wide admin consent in Azure Active Directory. The required Microsoft Graph API application permissions are: ChannelMessage.Send (to post bridged Webex messages into Teams), ChannelMessage.Read.All (to capture Teams messages for forwarding to Webex), and TeamMember.Read.All (for identity mapping). This is a one-time consent — after it is granted, non-admin users can manage channel mappings from the SyncRivo dashboard without further admin involvement.

Webex authorization uses OAuth2 via the Webex Developer portal. In SyncRivo, click "Add Platform" → Cisco Webex. You are redirected to Webex OAuth — sign in with a Webex administrator account and grant scopes: spark:messages_read, spark:messages_write, spark:rooms_read, and spark:memberships_read. SyncRivo creates a Webex bot after authorization. You must add this bot to each Webex Space you want to bridge by entering the bot email in the Space's People settings.

SyncRivo bridges text messaging channels only. Webex Calling (Cisco UCM/Webex PSTN) and Microsoft Teams Phone (Teams calling with a phone number) are separate voice infrastructure systems that do not interoperate via SyncRivo. However, meeting links from both platforms (Webex meetings, Teams meetings) are forwarded as clickable URLs across the bridge, so the other team can join if they have a compatible browser or the respective app installed. For voice/video interoperability between Teams and Webex, consider Cisco's dedicated Webex for Microsoft Teams app.

Teams Adaptive Cards (interactive message cards used by many Teams apps and bots) are not natively supported in Webex. SyncRivo does not relay messages posted by Teams apps and bots, so Adaptive Cards do not cross the bridge; only human messages are bridged, and their text is delivered to the Webex Space. Interactive card elements (buttons, dropdowns, form inputs) are never replicated. For rich content, post plain text summaries in mapped channels.

The bridge uses TLS in transit, encrypts provider OAuth tokens at rest, and does not store message content on the normal relay path (only message IDs are kept; an optional retry queue temporarily holds undelivered messages). Both Cisco Webex and Microsoft Teams have their own compliance configurations (Webex Control Hub data retention, Teams eDiscovery) that remain independent of SyncRivo. SyncRivo does not currently hold a SOC 2 report and is not FedRAMP authorized; a security questionnaire and architecture review are available on request.

Yes. SyncRivo can bridge private Teams channels and channels within private Teams (not just public Teams). For private channels, the SyncRivo app needs to be explicitly added as a member of the private channel by a channel owner. This is done in Teams Admin Center → Manage Teams → select the Team → Channels → click the private channel → Members → Add SyncRivo app. Note that Microsoft Graph API access to private channels requires the ChannelMessage.Read.All permission scoped to the specific channel — standard Read.All scope may not cover private channels in some Azure AD tenant configurations.

SyncRivo uses identity mapping to display the sender's real name. When a Teams user sends a message, SyncRivo resolves the Microsoft UPN (e.g., user@contoso.com) to the matching Webex account (e.g., same email in Webex) and attributes the message with the sender's display name. For cross-domain setups (M&A scenarios where email domains differ), you upload a CSV mapping Microsoft UPNs to Webex email addresses. Without identity mapping, messages appear attributed to the SyncRivo bot with a "(sent by: [original name])" annotation.
