Microsoft Teams connector reference

Operations, inputs, troubleshooting, and questions for the Microsoft Teams connection. Policy decides each change before the credential is resolved, and the action record carries the result.

Set up and verify the Microsoft Teams connection

Choose one task and its account, and match the reads and actions on the overview page to it before granting provider permissions.
Prepare the connection settings from the overview page, connect the provider in Deixic, and choose which tools your agent can use.
Try a small task with a known result, and compare the returned identity and resource with what the account owner expects.
Configure approval for sensitive changes, review the destination and inputs, and check the result in the provider before expanding the workflow.

Information your agent can use

Resource	Record identity	Start with	Page coverage
Joined teams	`id`	Top level	Next-page URL
Team channels	`id`	Joined teams	Next-page URL

Record identity: Match on these fields before joining or deduplicating results; where none is specified, check the returned record first.
Start with: Resolve the parent identifier first.
Next-page URL: Next-page URL. Follow the continuation returned by the provider before treating the collection as complete.

Supported operations

Review the inputs before granting an action to an agent. Required inputs must be supplied, optional inputs narrow the request, and provider permissions apply in addition to Deixic policy.

Action: Can change provider state; review the target and inputs, then retain the result to avoid repeating completed work.

When the Microsoft Teams task does not produce the expected result

Connected, but the expected data is missing

Check the identity behind the oauth connection and its access to the specific resource; a successful connection does not establish access to every object.

Resolve parent resources first: Joined teams. A matching display name is not enough for a child lookup.

The answer covers only part of the data

Check the resource’s page coverage, query filters, and result limit, and have the agent state the account and time window it inspected, so a partial response yields a scoped answer.

The agent keeps doing the same work

Inspect the action history for repeated targets and inputs, keep the successful result’s identifiers with the task, and refresh a lookup only when the information changed.

A change is waiting or failed

Check whether the call awaits approval, was rejected by policy, lacks an input, or failed at the provider, and after a timeout inspect the destination before repeating a write.

Questions about the Microsoft Teams connector

Can I use my existing agent with Microsoft Teams?

Yes: connect your agent to Deixic through MCP, choose which connected tools it can use, and Deixic checks calls routed through its gateway; Dex is available if your team also wants an agent.

Can an agent change data in Microsoft Teams?

This connector supports 1 action, listed on its overview page. Configure a connection and choose the tools and provider permissions your task needs; an available action is not permission for every agent to run it, and Deixic policy and any required approval still apply to calls through the gateway.

What do I need to connect Microsoft Teams?

Prepare Client ID, Client secret, Access token; the connection uses OAuth, and the connected identity’s provider permissions determine which resources it can access.

Does connecting Microsoft Teams keep every answer up to date?

No: an earlier answer is still an earlier answer, so for a decision that depends on current state, have the agent refresh the source and retain the lookup time, and save stable instructions separately from facts that can change.
