If your organization uses Microsoft 365 and your users want to connect their work calendars to Calendrz, you may need to grant consent on their behalf. Calendrz is a verified Microsoft application that only requests the minimum permissions needed to mirror calendar availability — no email access, no file access, no admin rights.
This guide walks you through three ways to approve Calendrz for your organization.
What permissions does Calendrz request?
Calendrz requests the following delegated (user-context) permissions — it never acts without a user present:
- openid, profile, email — Standard sign-in (name and email for account creation)
- offline_access — Keeps the connection alive so calendar mirroring runs in the background
- Calendars.ReadWrite — Reads busy/free status and writes blocker events to prevent double bookings
Calendrz does not request access to email, files, Teams, contacts, or any other Microsoft 365 data. It cannot read event details from other users — only the signed-in user’s own calendars.
Option 1: Grant admin consent from the Azure portal
This is the most common approach. It pre-approves Calendrz for all users in your organization so they can sign in without seeing a consent prompt.
- Sign in to the Microsoft Entra admin center as a Global Administrator or Cloud Application Administrator
- Navigate to Identity → Applications → Enterprise applications
- Search for Calendrz in the application list. If it does not appear yet, ask one of your users to attempt a sign-in first — the application will be registered automatically after the first consent attempt
- Select Calendrz from the results
- Go to Permissions in the left menu
- Click Grant admin consent for [your organization]
- Review the permissions listed and click Accept
Once approved, all users in your organization can sign in to Calendrz and connect their Microsoft 365 calendars immediately.
Option 2: Use the admin consent URL
If you prefer a quicker path, you can approve Calendrz by visiting a direct consent URL. Open the following link in your browser while signed in as an administrator:
https://login.microsoftonline.com/{your-tenant-id}/adminconsent?client_id=YOUR_CALENDRZ_CLIENT_ID
Replace {your-tenant-id} with your organization’s Azure AD tenant ID (found in Entra admin center under Overview). If you’re unsure of the Calendrz client ID, contact support@calendrz.com and we’ll provide it.
After clicking Accept, Calendrz is approved organization-wide.
Option 3: Allow users to consent individually
If your organization’s policy allows user consent for verified applications, no admin action is needed. Users will see a standard Microsoft consent screen when they first sign in to Calendrz, listing the permissions requested. They can accept and proceed on their own.
To check or update your organization’s consent policy:
- In Entra admin center, go to Identity → Applications → Enterprise applications → Consent and permissions
- Under User consent settings, select “Allow user consent for apps from verified publishers, for selected permissions”
- This allows users to consent to low-risk permissions from verified apps like Calendrz without needing admin approval
What happens after consent is granted?
Once Calendrz is approved, your users can:
- Sign in at app.calendrz.com using their Microsoft 365 work account
- Connect their work calendar — Calendrz automatically detects all calendars in their account
- Mirror availability — When they’re busy in one calendar, Calendrz auto-blocks that time in their other connected calendars (Google, personal Outlook, or additional Microsoft 365 accounts)
No calendar event details are ever shared between accounts. Calendrz only mirrors the time slots — the content of events stays private.
Revoking access
If you need to revoke Calendrz access for your organization at any time:
- Go to Entra admin center → Enterprise applications → Calendrz
- Select Properties
- Set Enabled for users to sign-in? to No
- Click Save
This immediately prevents any new sign-ins. Existing connections will stop working when the current access token expires (typically within one hour).
