Connecting Google & Microsoft 365

The cloud side of a connection is Google Calendar or Microsoft 365. Both connect through OAuth — a one-click authorization where you sign in at the provider and grant calendar access. CalDAVconnect never sees or stores your Google/Microsoft password.

Connecting Google Calendar

1. In your connection, choose Connect Google.
2. Sign in to your Google account and approve calendar access.
3. You're redirected back and the calendars on that account become available for pairing.

Any Google account works — personal @gmail.com as well as Google Workspace.

Connecting Microsoft 365

1. Choose Connect Microsoft.
2. Sign in and approve calendar access.
3. You're redirected back and your calendars become available for pairing.

Both work/school (Microsoft 365 / Entra ID) and personal Microsoft accounts are supported. If your organization restricts third-party apps, an admin may need to approve access.

What permissions are granted

CalDAVconnect requests read and write access to your calendars — enough to create, update and delete events so changes can flow in both directions. It does not request access to your mail, contacts or files.

Revoking and re-authorizing

You stay in control: revoke access any time from your Google account or Microsoft account settings.

If a token expires or you change your provider password, the connection may enter a re-authorization state. When that happens, your dashboard shows a prompt — click Reconnect, sign in again, and syncing resumes immediately. You don't lose any pairing or settings.
