Before you start.

An Outlook.com mailbox or a work or school Microsoft account with the mail or calendar service you want. Your organization may require administrator approval.

What you can do

  • Search and read mail, inspect selected file attachments up to 10 MB, and create drafts or in-thread reply drafts; send only after approval.
  • Read upcoming calendar events for meeting detection and daily context.

Connect Outlook.

  1. Find Outlook in Doppel.

    Open Settings → Integrations → Add integration. Select Outlook, then Connect.

  2. Choose Mail, Calendar, or both.

    In Connect Microsoft, turn on only the services you want Doppel to use.

  3. Authorize the right Microsoft account.

    Sign in and review the requested access. If your organization requires administrator approval, follow that process before continuing.

  4. Return to Doppel.

    Finish the browser authorization, then return to Settings → Integrations. Check that access was granted before trying the example below.

Choose what to remember.

With Pro or the trial, use Manage sources to remember selected content and assign it to a project. This is an additional, separately authorized connection.

  1. Open Manage sources.

    Go to Settings → Integrations → Manage sources. In Selected sources, choose Add account. This is separate from Add integration.

  2. Add the source account.

    Select the service and give the account a label. Sign in to the account that owns the source, or approve macOS access for Apple Calendar and Reminders. This account is stored separately from your primary integration connection.

  3. Choose where the source belongs.

    Select Choose source. Set Use in to the intended Doppel project, or All-work chats only. A source assigned to one project cannot be requested from another project’s chat.

  4. Select what to remember.

    Choose a mail folder from the list, including an archive or custom folder.

  5. Check the import.

    Choose Add source, then inspect its coverage and Last complete sync. Use Sync now to refresh it. Ask a question in the project you assigned, or an All-work chat if you chose All-work chats only.

What this imports

Messages in the selected folder, with moves and deletions reconciled after a complete scan. This source account is mail-only; the primary Outlook connection’s optional calendar is separate.

Check each source’s coverage and Last complete sync. If access becomes unavailable, the source is excluded from answers until a complete sync succeeds.

Start with something you know

Check the connection.

Find the Outlook email about next week’s project review.

For Mail, compare a known message with Outlook. For Calendar, ask about a known upcoming event. The integration row should show which services are connected.

Data and permissions.

Mail is indexed locally when selected, and calendar events can supply local context. Microsoft receives live requests, saved draft content, and messages you approve sending.

Current limits

The calendar connection reads the account’s default calendar and is read-only; it does not enumerate all shared or secondary calendars. Selecting Calendar alone does not index mail, and a Microsoft identity without a mailbox is not enough for mail access.

See what stays local and what uses the network

Disconnect or change access.

Disconnecting Outlook stops both Mail and Calendar access and removes locally indexed Outlook mail. Use Change access to choose a different combination of services. Saved calendar context and chats are separate; an account also connected through Apple Calendar can still supply events. Revoke provider-side authorization separately in your Microsoft account if needed.

Selected-source accounts are separate. In Manage sources, remove an individual source or disconnect its account to remove those imported copies and credentials. Disconnecting the primary integration alone does not remove a separately authorized source account. Provider originals, saved chats, and exports are managed separately.

If something isn’t working.

Calendar works but mail does not

Check that Mail is selected in Change access and that the connected account has a mailbox. A work account’s administrator may need to approve mail access.

Still stuck? Email support@doppelapp.ai with your Doppel version, the service, and the error shown. Keep passwords, access tokens, and API keys out of your message.
