    What this connector does

    • Connect Microsoft 365 with your own sign-in. Atlas keeps the connection details encrypted.
    • Show on the connector page whether Microsoft 365 is connected and which permissions were granted.
    • Read your Outlook inbox and Teams lists whenever someone in Atlas asks for it.
    • Background mailbox and channel sync and subscriptions are set up separately and are not switched on by connecting.

    Before you begin

    • You are an owner or administrator of your Atlas workspace.
    • You can sign in to your Microsoft 365 account and approve access for Atlas.
    • Atlas looks after the Microsoft 365 app on its side, so there is nothing for you to create or copy.

    How to connect

    1

    Open Microsoft 365 in Integrations

    In Atlas, open Integrations and select Microsoft 365.

    2

    Press Connect

    Atlas sends you to Microsoft 365 to sign in. Sign in with the account you want to connect.

    3

    Approve access

    Review the permissions that Microsoft 365 lists and approve them. Atlas returns you to the connector page, which then shows the connection.

    4

    Check the connection

    Select Test connection on the connector page. A passing result means Atlas can read from Microsoft 365.

    Setup checklist

    1. Confirm you are an owner or administrator of your Atlas workspace.
    2. Open Integrations and select the connector.
    3. Press Connect and sign in to Microsoft 365.
    4. Review the permissions that Microsoft 365 lists and approve them.
    5. Select Test connection and read the result.

    Troubleshooting

    • Microsoft read check is blocked

      Check that the saved connection allows reading mail and Teams membership, then run the read check again.

    • Verification fails before connect

      Complete Microsoft consent before using Microsoft actions in Atlas.

    • Connect says Microsoft 365 is not available yet

      Atlas has not enabled Microsoft 365 for this deployment, so there is nothing for you to configure. Check again later.

    • The sign-in was cancelled

      If you close the Microsoft 365 screen or choose Cancel, Atlas does not connect. Press Connect again and approve the access.

    • Atlas asks you to reconnect

      Microsoft 365 can end a connection when access is revoked or a password changes. Press Reconnect on the connector page and approve the access again.

    Event notifications

    The manual check reads Outlook and Teams through Microsoft. Ongoing mail, Teams, file, and calendar subscriptions are set up separately from the connector page.

    Events Atlas listens for

    • Mail received
    • Teams channel message
    • Chat message
    • Calendar event changed
