Autocloz + Microsoft 365 / Outlook

Microsoft 365 / Outlook connects as a sending mailbox for the Email channel. You authorise your own Microsoft 365 / Outlook account — over OAuth where supported, or SMTP/IMAP credentials otherwise — and Autocloz sends through it and pulls replies back into the unified inbox. Sending reputation stays on your own Microsoft 365 / Outlook infrastructure.

What you can do with Microsoft 365 / Outlook

Microsoft 365 / Outlook plugs into the Email stack — connect via oauth or smtp/imap, scoped to your workspace.

Send from your mailbox

Outbound email goes through your own connected account, so replies land in your real inbox and your sending reputation stays yours.

Replies in the unified inbox

IMAP (or the provider API) syncs replies back into Autocloz so the whole thread lives next to the lead, not split across tools.

Bulk mailbox onboarding

Connect many mailboxes through the wizard so a team can rotate sends across accounts without configuring each one by hand.

How to connect Microsoft 365 / Outlook

Connect via OAuth or SMTP/IMAP — you keep control of the account, the spend and the data boundary.

  1. 1

    Have your Microsoft 365 / Outlook account ready

    Microsoft 365 / Outlook is the mailbox you send from — bring an account you control. Autocloz does not host the mailbox; sending reputation stays on your infrastructure.

  2. 2

    Connect over OAuth or SMTP/IMAP

    In Settings → Channels → Email, add Microsoft 365 / Outlook. Use OAuth where the provider supports it, otherwise paste SMTP/IMAP host, port and credentials.

  3. 3

    Confirm send + reply sync

    Send a test email and reply to it — confirm the outbound lands and the reply appears back in the unified inbox against the lead.

  4. 4

    Warm up and start sequencing

    Let new mailboxes warm before high volume, then enroll leads. Deliverability tooling (SPF/DKIM/DMARC checks, warmup) keeps sends healthy.

Part of the Email stack

Microsoft 365 / Outlook is one of the providers behind the Email channel. All mailboxes share the same sequencing, unified inbox, and deliverability tooling regardless of provider.
