How to connect multiple One drive accounts to Claude

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

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

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

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

For example:

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

Using the one_drive-1 account, share project folder with my team.

• A Claude account
• A free Composio account
• Access to each One drive 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 One drive account

In a new Claude chat, type:

Connect my one_drive-1 One drive account to Composio. Call it one_drive-1.

Claude will give you a sign-in link.

1. Click the link.
2. Sign in to your one_drive-1 One drive account.
3. Review and approve One drive's permission request.
4. Return to Claude.

Claude should confirm that the account is connected.

The name one_drive-1 is how Claude knows which One drive account to use. Choose short, obvious names. Good examples include:

• one_drive-1
• one_drive-2
• one_drive-3

Step 3: Connect your second One drive account

In the same Claude chat, type:

Connect another One drive account. Call it one_drive-2.

Claude will give you a new sign-in link.

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

Claude should confirm that one_drive-2 is connected.

Important: Check that One drive 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 One drive account you want to add. Give each connection a short, descriptive name such as one_drive-1, one_drive-2, one_drive-3, or client-acme.

Step 4: Check your connected One drive accounts

Ask Claude:

List my connected One drive 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 One drive account.

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

Step 5: Use the right One drive account

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

Review activity across accounts

Check one_drive-1 and one_drive-2 for anything new in One drive from the last 14 days. Group the results by account.

Download the latest version of report.docx

Using the one_drive-1 account, download the latest version of report.docx.

Check who can access budget.xlsx

Using the one_drive-2 account, check who can access budget.xlsx.

Find something across accounts

Search all connected One drive 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 One drive accounts are: one_drive-1 = my main account, one_drive-2 = my second account, and one_drive-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 One drive 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 One drive 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 One drive.
5. Click Connect and complete the One drive authorisation flow.
6. Click Connect again to add another One drive account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as one_drive-1, one_drive-2, or one_drive-3.

If One drive 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 one_drive-2 is no longer useful.
• Disconnect or delete an account you no longer want Claude to access.
• Re-authorise an expired or revoked connection.
