If a calendar account in the dashboard shows **"Please reconnect"** (you'll also get an email), access to the provider has expired or was revoked. Sync pauses until then — **nothing is lost.**

## How to reconnect

1. Click **"Reconnect"** on the affected account in the dashboard.
2. Complete the provider sign-in (or, for Apple/KSuite, re-enter the app password — possibly [create a new one](https://docs.kalender-sync.de/en/connect-calendar/apple-icloud/) first).
3. Done — sync automatically catches up on everything that changed in the meantime.

## Why does this happen?

- You **changed your password** at the provider or **revoked** access manually.
- A **security policy of your organisation** reset the access grants.
- The **app password** (Apple/KSuite) was deleted or expired.

## Still not working?

- Error message **inside the provider sign-in** ("Need admin approval" or similar) → [My organisation blocks the connection](https://docs.kalender-sync.de/en/connect-calendar/org-blocked/)
- Other connection errors → [Connection fails](https://docs.kalender-sync.de/en/troubleshooting/connection-fails/)
