How to connect multiple Microsoft teams accounts to Claude

Claude's built-in Microsoft teams connector works well if you use one Microsoft teams account. But when you connect a second account, it replaces the first.

If you manage separate Microsoft teams accounts for different products, regions, or business units, that quickly becomes frustrating.

Composio fixes this by keeping each Microsoft teams account separate and giving it a simple name, such as microsoft_teams-1, microsoft_teams-2, or microsoft_teams-3. Claude can then use the right Microsoft teams account when you mention that name.

• One Composio connector in Claude
• Two or more Microsoft teams accounts connected behind it
• A clear name for each account
• The ability to work in the right Microsoft teams account from a single Claude chat

For example:

Search my microsoft_teams-1 and microsoft_teams-2 Microsoft teams accounts for anything that needs my attention from the last 7 days. Tell me which account each item came from.

Using the microsoft_teams-1 account, add new member to project team.

• A Claude account
• A free Composio account
• Access to each Microsoft teams account you want to connect

If you use Claude Free, you can have one custom connector. If you already use that slot, you will need to remove the existing custom connector first.

If you use Claude Team or Enterprise, an Owner may need to add the connector for the organisation. Each member can then connect their own accounts.

Step 1: Add Composio to Claude (one-time process)

1. Click the button below. This will take you to the Claude Custom Connector modal.

Add to Claude

2. Click Continue

3. In the next modal, click Add

4. It will take you to the authentication page. Sign in to Composio and approve the connection.

Then return to Claude and make sure Composio is enabled.

Step 2: Connect your first Microsoft teams account

In a new Claude chat, type:

Connect my microsoft_teams-1 Microsoft teams account to Composio. Call it microsoft_teams-1.

Claude will give you a sign-in link.

1. Click the link.
2. Sign in to your microsoft_teams-1 Microsoft teams account.
3. Review and approve Microsoft teams's permission request.
4. Return to Claude.

Claude should confirm that the account is connected.

The name microsoft_teams-1 is how Claude knows which Microsoft teams account to use. Choose short, obvious names. Good examples include:

• microsoft_teams-1
• microsoft_teams-2
• microsoft_teams-3

Step 3: Connect your second Microsoft teams account

In the same Claude chat, type:

Connect another Microsoft teams account. Call it microsoft_teams-2.

Claude will give you a new sign-in link.

1. Open the link.
2. Sign in to the second Microsoft teams account.
3. Review and approve Microsoft teams's permission request.
4. Return to Claude.

Claude should confirm that microsoft_teams-2 is connected.

Important: Check that Microsoft teams is showing the second account before you approve access. If the wrong account appears, sign out or open the link in an incognito or private window.

Repeat this step for every other Microsoft teams account you want to add. Give each connection a short, descriptive name such as microsoft_teams-1, microsoft_teams-2, microsoft_teams-3, or client-acme.

Step 4: Check your connected Microsoft teams accounts

Ask Claude:

List my connected Microsoft teams accounts in Composio. Show each account's name and connection status.

You should see every account you added, and each connection should show as ACTIVE.

For an extra check, ask:

Show the account email or ID and the account name for each connected Microsoft teams account.

This helps you confirm that every label points to the correct Microsoft teams account and that you did not connect the same account twice.

Step 5: Use the right Microsoft teams account

Mention the account name whenever you ask Claude to work with Microsoft teams. This is especially important when an action could change data.

Review activity across accounts

Check microsoft_teams-1 and microsoft_teams-2 for anything new in Microsoft teams from the last 14 days. Group the results by account.

Schedule an online meeting for sales

Using the microsoft_teams-1 account, schedule an online meeting for sales.

List all chats I’m part of

Using the microsoft_teams-2 account, list all chats I’m part of.

Find something across accounts

Search all connected Microsoft teams accounts for customer@example.com. Show which account it appears in and summarise the latest activity.

For actions such as creating, changing, or deleting data, ask Claude to show you the planned action first and wait for your confirmation.

Add this to your Claude preferences or project instructions, replacing the examples with your own account names:

My Microsoft teams accounts are: microsoft_teams-1 = my main account, microsoft_teams-2 = my second account, and microsoft_teams-3 = a client account. Always use the named account when I specify one. If I do not name an account, ask me which one to use. Before creating, changing, or deleting anything, show me the planned action and wait for confirmation.

If Claude's built-in Microsoft teams connector is also enabled, Claude may use it instead of Composio. For a clearer setup, turn off the built-in connector or explicitly tell Claude to use Microsoft teams through Composio.

The chat method is the quickest way to connect accounts. Use the dashboard when you want to add, rename, reconnect, or remove a connection.

1. Go to dashboard.composio.dev.

2. Sign in with the same Composio account you connected to Claude.
3. Open For You from the product switcher.
4. Find Microsoft teams.
5. Click Connect and complete the Microsoft teams authorisation flow.
6. Click Connect again to add another Microsoft teams account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as microsoft_teams-1, microsoft_teams-2, or microsoft_teams-3.

If Microsoft teams opens the wrong account during authorisation, sign out first or use an incognito or private window.

From the dashboard, you can also:

• Rename a connection when a default label such as microsoft_teams-2 is no longer useful.
• Disconnect or delete an account you no longer want Claude to access.
• Re-authorise an expired or revoked connection.
