If your company lives in Microsoft 365, the question isn't whether Nautis supports Outlook. It does, as one of the two calendar and email providers Liftoff offers. The real question is whether your tenant will let you connect it without a ticket to IT, and that depends on settings your admin chose long before Nautis came along.
Outlook is a built-in integration. It powers modules directly, rather than sitting in the agent catalog with a separate switch.
One sign-in, three modules
Google asks twice during setup, once for calendar and once for Gmail. Microsoft asks once. In Liftoff, click Connect next to Outlook and that one sign-in covers mail and calendar together.
After setup, Outlook shows up in three places. MailBox can hold your Outlook inbox next to other accounts, with Outlook offered as a provider when you click Connect mailbox. Meetings uses your Outlook calendar to block busy time and write bookings. Each person connects their own from Integrations in the Meetings sidebar, with no admin needed, and it gives agents no access. The Chief of Staff uses the calendar to find free slots and avoid clashes.
MailBox and the Meetings calendar are separate connections. You can keep an Outlook inbox in MailBox while Meetings runs on Google Calendar, or the other way round.
Before you click Connect: work accounts and admin consent
Microsoft splits app access into two kinds. Delegated permissions let an app act for a signed-in person, and Microsoft's permissions overview says such an app can't reach anything that person couldn't. Application permissions work with nobody signed in, and only an admin can grant those.
The mail and calendar permissions an email client typically asks for are delegated, and Microsoft's Graph permissions reference lists none of the ones below as needing admin consent. Microsoft doesn't publish which ones Nautis requests. The consent screen does, so read it.
| Permission | What Microsoft says it allows | Admin consent required |
|---|---|---|
| Mail.Read | Read the signed-in user's mailbox | No |
| Mail.ReadWrite | Create, read, update and delete email in user mailboxes, without sending | No |
| Mail.Send | Send mail as users in the organization | No |
| Calendars.Read | Read events in user calendars | No |
| Calendars.ReadWrite | Create, read, update and delete events in user calendars | No |
No admin consent required doesn't mean you'll get through. Microsoft's guide to user consent settings lets admins block user consent entirely, or allow it only for apps from verified publishers and for permissions they've classed as low impact. If your tenant does that, you'll see a request for admin approval instead of the usual consent screen. Admins can turn on an admin consent workflow so that request reaches them.
Connecting Outlook in each place
During Liftoff
- On the tools step, click Connect next to Outlook.
- Sign in with your Microsoft work account in the window that opens. It closes itself when you're done.
- With a calendar connected, click Continue.
In MailBox
- Open MailBox and click Connect mailbox, then Outlook.
- Approve access on Microsoft's page. You land back in the inbox with your address confirmed.
- New mail arrives within seconds. Older mail finishes indexing over a few minutes.
Each MailBox account uses one slot. Launch includes one, Voyage two and Fleet five, with more available as paid slots (see pricing).
How do Microsoft Teams meeting links work in Nautis?
When you build an event type or a one-off meeting in Meetings, Microsoft Teams is one of the location types, next to Google Meet, Zoom, Phone Call, In Person and Custom Link. The guide says video options need the matching integration connected, and show as not connected otherwise.
The guide doesn't name the exact connection Teams needs. The practical test takes a minute: create a draft event type, open Location Type, and see whether Teams is available. If it says not connected, open Integrations and check what's missing before you share the booking link with anyone.
A sales-led week on Outlook
Say you run enterprise pilots and live in Outlook. On Monday you set up a one-off New Meeting for a weekly pipeline review, with Recurrence set to weekly, Teams as the location, and your two account executives added from Team Members. Each gets an email invite with a calendar file attached.
On Wednesday a buyer in Singapore writes at 11 pm your time. In MailBox you use Suggest reply, run Rewrite tone to make it more formal, and pick Scheduled send so it lands in their morning. A procurement question goes to a colleague with Assign, so nobody forwards the thread around.
When the buyer asks for a call, your Chief of Staff checks your Outlook calendar and drafts a reply with times. It waits as a card until you approve, because sends and bookings ask first by default. An owner or admin can change that under Agent Autonomy.
Fixing Outlook connection problems
- Need admin approval. Your tenant restricts user consent. Ask your Microsoft admin to approve the app or enable the admin consent workflow.
- Yellow banner in Meetings. Microsoft revoked access or the token expired. Click Reconnect.
- MailBox error on the Outlook account. Disconnect and reconnect it from Email settings.
- Teams shows as not connected. The matching integration isn't connected yet. Check Integrations.
- Outlook events don't block your booking page. Confirm the calendar is connected in Meetings and use the refresh button next to New Meeting.
- A connection in Integrations shows Expired. Click Reconnect on the account row. Nothing else changes.
FAQ
Does the Nautis Outlook integration need my IT admin?
Sometimes. Microsoft lets people consent to mail and calendar permissions by default, but tenant admins can restrict or turn off user consent. If you see a request for admin approval, your admin has to approve Nautis first.
Can I use Outlook for email and Google for my calendar?
Yes. MailBox mailboxes and the Meetings calendar are separate connections, so an Outlook inbox can sit next to a Google calendar. Liftoff needs at least one calendar from Google or Microsoft to continue.
Will Nautis delete anything in my Outlook calendar?
The setup guide says your Chief of Staff never deletes emails or calendar events. Bookings and sends wait for approval by default, and every action is logged in AI Activity for owners and admins.
Can people book a Teams call with me through Nautis?
Yes, if Microsoft Teams is connected. Pick Teams as the location on an event type and share its booking link. Bookers don't need a Nautis account, only a name and email.
