Connect STRATO

BasicAvailable on Basic and up·Compare plans

You connect the calendar of your STRATO mailbox over CalDAV — with your mailbox address and your mailbox password. There is nothing to create beforehand. After that everything runs automatically, and sync picks up changes every 5 minutes.

The most common pitfall

You need the password of your email mailbox — not the password of the STRATO customer login you use to manage contracts and domains. And with STRATO the address usually sits on your own domain (e.g. name@your-company.com), not on @strato.de.

Requirement

You need a STRATO mailbox with a calendar — that comes with Webmail Premium and Webmail Business. To check, sign in to STRATO Webmail: if you see a calendar there, you’re set.

Connect in Kalender Sync

1. In the dashboard, go to “Connect calendar” → “STRATO”.
2. Enter your full mailbox address — exactly the one you use to sign in to STRATO Webmail.
3. Enter your mailbox password and click “Test & Connect” — Kalender Sync checks the connection right away.

You don’t need to enter the server address (dav.webmail.strato.de) — Kalender Sync knows it and finds your calendars automatically.

Prefer a password just for Kalender Sync?

STRATO Webmail also offers application passwords. They aren’t required, but you can create one and use it here instead of your mailbox password. That way you can revoke access later without changing your mailbox password.

If you see “Sign-in failed”

• Does signing in at webmail.strato.de work with the same details? If not, the address or password is wrong.
• Did you really use the mailbox password, not the customer login password?
• Changed your mailbox password recently? Then reconnect with the new password.
• No calendar found? Your plan probably doesn’t include a calendar (see Requirement).

Still stuck? Write to us at support@kalender-sync.de — the STRATO connection is new, so every report helps.

End access

In Kalender Sync: Remove a calendar. If you used an application password, you can also delete it in STRATO Webmail — that ends access immediately. With the mailbox password, access ends as soon as you change it.
