"Please reconnect" — connection expired
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account in the dashboard shows “Please reconnect” (you’ll also get an email), access to the provider has expired or was revoked.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
Section titled “How to reconnect”- Click “Reconnect” on the affected account in the dashboard.
- Complete the provider sign-in (or, for Apple/KSuite, re-enter the app password — possibly create a new one first).
- Done — sync automatically catches up on everything that changed in the meantime.
External sharing? If the target calendar lives in the recipient’s account, the recipient has to reconnect that account in their own Kalender Sync login. The sender sees the status “Reauth needed” on the sharing but cannot repair the account themselves.
Why does this happen?
Section titled “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?
Section titled “Still not working?”- Error message inside the provider sign-in (“Need admin approval” or similar) → My organisation blocks the connection
- Other connection errors → Connection fails
