# Known limitations

We'd rather document limitations openly than have you ask support about them. If one of these concretely blocks you, [tell us](https://docs.kalender-sync.de/en/troubleshooting/contact-support/) — it feeds directly into prioritisation. *(As of: July 2026)*

## Current limitations

| Limitation | Details | Status |
| --- | --- | --- |
| **Two-way sync: calendar pair fixed** | Options (visibility, prefix, …) are [editable](https://docs.kalender-sync.de/en/sync/freigabe-bearbeiten/) per direction; the two calendars themselves cannot be swapped — end + recreate for that | — |
| **Sync window not freely adjustable** | −3 months back for everyone; ahead +6 months (Free & Basic) or +18 months (Professional) → [details](https://docs.kalender-sync.de/en/sync/sync-window/) | Freely configurable planned |
| **No iCal export** | Kalender Sync can **read** feeds but not yet generate its own feed URL to subscribe to — relevant for [blocked organisations](https://docs.kalender-sync.de/en/connect-calendar/org-blocked/) | Planned |
| **Email address not changeable** | The address is the account anchor → [workaround via support](https://docs.kalender-sync.de/en/account-billing/profile-notifications/) | Planned |
| **5-minute cadence for Apple/KSuite/iCal** | Technical limit of these providers (no push) — Google/Microsoft run almost instantly on Basic and up | Stays for now |
| **30-minute interval on Free** | The Free plan syncs on a 30-minute interval; real-time webhooks for Google/Microsoft are included from Basic → [Plans & limits](https://docs.kalender-sync.de/en/account-billing/plans-limits/) | By plan design — upgrade for real-time |
| **No team/organisation accounts** | Each user has their own account; central management and consolidated billing don't exist yet | On the roadmap |
