Outlook Calendar
In one line: Connect your Microsoft Outlook calendar so your UnleashX agent can check availability, schedule meetings, update or cancel events, and manage multiple calendars for you.
1. Overview
Outlook Calendar is Microsoft’s scheduling service inside Microsoft 365. It holds your meetings, appointments, and reminders across one or more calendars, and it’s tightly tied to your Outlook mailbox. Once connected to UnleashX, your agent can look up what’s on your schedule, find a free slot, create a new event with attendees, reschedule or update meetings, and cancel events you no longer need. It can also work across multiple calendars — for example a personal calendar and a shared team calendar. Connecting Outlook Calendar to UnleashX means scheduling happens in plain language. Instead of clicking through the calendar grid, you can ask “set up a 30-minute call with Sam on Thursday afternoon” and the agent finds the time and creates the event.2. What you’ll need
- A Microsoft account with Outlook Calendar (personal
@outlook.com/@hotmail.com, or a Microsoft 365 / Exchange Online work or school account). - Permission to use that calendar — for work accounts, your organization must allow third-party apps via Microsoft Graph.
- An UnleashX account with access to Data Connectors.
No API key required. Outlook Calendar uses OAuth — you click Authorize and sign in with Microsoft.
3. Get your credentials
There’s no key to copy. Authentication runs through Microsoft’s secure OAuth sign-in.1
Start the connection in UnleashX
Connecting Outlook Calendar (Section 4) opens a Microsoft Authorize window.
2
Sign in with Microsoft
Sign in with your Microsoft 365 / Outlook account at
https://login.microsoftonline.com and complete MFA if prompted.3
Review and accept the permissions
Microsoft displays exactly what UnleashX requests (see the scopes table). Click Accept.
4
Return to UnleashX
You’re redirected back automatically and the calendar is connected.
These are standard Microsoft Graph delegated scopes, enforced by Microsoft. UnleashX can never exceed the access you approve.

9. Frequently asked questions
Is my calendar data stored by UnleashX? No. UnleashX reads and writes events live through Microsoft Graph for each request; it doesn’t keep a copy of your calendar. Can multiple team members connect their own calendars? Yes. Each person authorizes their own Microsoft account, so the agent works against each user’s own calendars. Can the agent manage shared or team calendars? Yes, as long as those calendars are shared with the signed-in account and the granted scopes allow editing. Will deleting an event cancel it for attendees? Deleting an event you organize generally sends cancellations, the same as deleting it in Outlook. Treat Delete Event as a real cancellation.10.
