How to Bridge Microsoft Teams and Google Chat(2026 Step-by-Step Guide)

No. Teams and Google Chat are closed ecosystems with no built-in messaging bridge. A Teams user cannot send a message that appears in a Google Chat Space, and vice versa. Workarounds like shared email channels or Slack bridges introduce friction and latency. SyncRivo creates a direct bidirectional bridge at the API level — Teams messages appear in Google Chat in real time, and replies flow back to Teams, with no guest accounts or platform switching required.

You need Google Workspace super admin access or domain-wide delegation to authorize SyncRivo. In the Google Admin console, navigate to Security → API controls → Manage third-party app access. You will also need to create a Google Cloud project and configure OAuth2 consent (internal type is sufficient for most orgs). The required scopes are: chat.messages (read/write), chat.spaces (read), and chat.memberships (read). Crucially, no external sharing policy changes are needed — SyncRivo operates as a service account within your domain.

SyncRivo requires tenant-wide admin consent in Azure Active Directory for three Graph API permissions: ChannelMessage.Send (to post bridged messages), ChannelMessage.Read.All (to read messages for forwarding), and TeamMember.Read.All (for identity mapping). A Teams Administrator or Global Administrator must perform this one-time consent. After consent, no further admin involvement is needed for day-to-day operation — non-admin users can manage channel mappings from the SyncRivo dashboard.

Yes, with some nuance. SyncRivo bridges both threaded Google Chat Spaces and flat (inline reply) Spaces. Thread context is preserved bidirectionally — a Teams reply to a threaded message appears as a threaded reply in the corresponding Google Space, and vice versa. Google Chat direct messages (1:1 DMs) are not bridged; only Spaces with defined membership are eligible. Google Chat bot messages are excluded from bridging by default to prevent bot loops.

Yes. This is one of the most common enterprise use cases: a company on Microsoft 365 acquires a Google Workspace company, and Day 1 messaging is critical. SyncRivo connects cross-tenant and cross-domain — your Teams tenant in contoso.com can bridge to a Google Chat organization in acme.com without any domain federation or DNS changes. Each side authorizes SyncRivo independently, and SyncRivo routes messages between them with identity mapping (so messages show the sender's real name and avatar on both sides).

SyncRivo is HIPAA-ready: zero message storage, TLS 1.3 in transit, per-tenant key isolation, role-based access controls, and audit logging. A Business Associate Agreement (BAA) is available on Enterprise plans. Note that Microsoft Teams has HIPAA-eligible configurations under Microsoft 365 Government plans; Google Workspace is HIPAA-eligible when the correct settings and BAA with Google are in place. Both platforms plus SyncRivo must be individually configured for HIPAA — SyncRivo alone does not make your endpoints compliant. Contact the SyncRivo enterprise team to discuss healthcare bridge requirements.

SyncRivo does not back-fill historical messages. Only messages sent after activation appear on the other side. This is intentional — retroactive bridging raises compliance questions about data residency and consent. For onboarding teams across platforms, best practice is to create a pinned message in each mapped channel announcing the bridge start date, so both teams know when cross-platform history begins. SyncRivo's monitoring dashboard shows a full audit log of every bridged message from activation onward.

SyncRivo uses identity mapping to display the sender's real name and avatar. When a Teams user sends a message, SyncRivo resolves their Microsoft identity (via Graph API) to their Google identity (via Workspace Directory API) if both accounts share the same corporate email domain. For cross-domain bridging (different companies), SyncRivo displays the sender's name with a "(via SyncRivo)" attribution and uses the platform-native avatar from the source side. Custom avatar uploads for each mapped identity are available on Enterprise plans for M&A scenarios where email domains diverge.
