iClosed Calendars is the page where you can connect your personal or work calendars with schedule, so events, availability, and bookings are in perfect sync.
You'd want to connect your Outlook account so you can:
get updates about your new bookings in the calendar connected
iClosed can check for availability conflicts with the calendar connected
send email reminders from your Outlook when Host email is selected (that you can set up in Event Notifications and Workflows)
Here's how you can connect Outlook with iClosed:
AI Scheduler → Calendar page or from
Settings → Calendars page orfrom
Integrations page
But bear in mind that Outlook Calendar integration works on a user level, meaning every user would need to connect their own calendar with iClosed account.
Follow the step by step guide to connect your Outlook with iClosed:
Go to
AI Scheduler → Calendar Click on 'Connect Outlook Calendar' button
You will be redirected to choose the account you want to connect
Select the account and grant all the necessary permissions

As you may know, we're offering Google calendar integration as well - check out the article about it here.
You will be able to connect only one main calendar where events will be stored from iClosed. Additional calendars can be included for conflict checks, and it can be Google or Outlook both.
I can't connect my Outlook due to "Admin Consent Required" error
Companies that have organizations on Microsoft will require admin consent for connecting Outlook calendar and Microsoft Teams.
Until admin consent is provided, users who are trying to connect Microsoft apps will see error message “Need admin approval” as the app will not appear in Enterprise Applications until this consent is given (this is a one-time setup per Microsoft organization). Here're the steps that admin need to take:
Step 1: Open the Admin Consent Link
Admin needs to open following link on Microsoft 365 / Entra admin:
Step 2: Sign In as Admin
Sign in using an admin account in your organization (Global Admin or Application Admin recommended).
Step 3: Review & Accept Permissions
Review requested permissions (e.g., calendar and user data access via Microsoft Graph) and click Accept.
And you're done. The app will be automatically added to your organization in Microsoft Entra ID. It will now appear under Enterprise Applications and permissions are granted tenant-wide.
Step 4: User can sign in
Once consent is granted user will be able to connect iClosed with Microsoft Teams or Outlook calendar without any additional approvals needed.
