If your calendar connection fails, the most common cause is a browser popup blocker preventing the OAuth window from opening. Allow popups for app.freshmango.ee and try again.
1

Allow popups

Check your browser’s address bar for a blocked-popup icon. Allow popups from app.freshmango.ee and reload the page.
2

Click Connect again

Go to the calendar integration page and click Connect Google Calendar or Connect Microsoft Calendar.
3

Grant all requested permissions

In the OAuth prompt, approve every permission Freshmango requests. Denying calendar-read or calendar-write access will break the integration.
4

Complete the callback

You are redirected to /auth/callback/:provider and back to Freshmango. Your calendar should now show as connected.

​
Other causes

  • Work Google Workspace blocks third-party apps — Some company administrators restrict OAuth apps. Ask your IT admin to approve Freshmango, or connect a personal Google account instead.
  • Already connected to a different account — If you previously connected a different Google or Microsoft account, disconnect it first in your Freshmango settings, then connect the correct one.
  • Browser extensions interfering — Ad blockers or privacy extensions may block the OAuth flow. Try in an incognito window.
  • Microsoft 365 admin consent required — Organizational Microsoft accounts sometimes require admin consent for calendar apps. Contact your IT team if you see an admin-consent error.

​
If that didn’t work

Contact support@freshmango.ee or visit /support/contact. Include your account email, which provider you are using (Google or Microsoft), a screenshot of the error, your browser and OS, whether you are on a work or personal account, and the timestamp of your last attempt.
