Support Center

Yes. We take over and manage existing Microsoft 365 tenants, including mailboxes, Teams, and security settings. You do not need to migrate to a new tenant or change your existing setup to start working with us.

A 24/7 helpdesk handles incoming requests around the clock via an external phone service, which escalates to a ThreeBIT technician in Germany when needed. For non-urgent matters you can also submit a ticket at any time through the support request form on this page.

We prioritise by urgency — critical incidents are picked up first. The more detail you provide when opening a ticket (see "How do I open a support ticket?"), the faster we can act on your request.

We are based in Ibbenbüren, Germany, and work with customers in German and English.

Use the support request form on this page — select your product or service, provide your customer number if you have one, and describe the issue. You will receive a confirmation by email once the ticket is created.

The form is open to everyone; a customer number is optional. Existing customers receive the fastest routing, and prospects are very welcome to reach out as well.

ThreeBIT GmbH is a German company and processes all personal data in accordance with the GDPR. Please see our privacy policy for full details.

You download our custom remote support client for your operating system from the section below, accept the remote support terms, and run it. You then share the connection ID it shows with your technician and accept the incoming request. We can see your screen and, if you grant it, control your computer — only while the session is live, and only to carry out the work you asked for. See "How ThreeBIT remote support works" in the Help Center for the full walkthrough.

Windows, macOS, Linux, and Android. Download the matching client from the Remote support client section below; the Help Center has a short step-by-step guide for each platform, including the permissions macOS and Android ask you to grant.

No. A session only starts when you run the client and accept the request, and our access ends the moment the session closes. We cannot reconnect silently — every ad-hoc session needs a fresh acceptance from you. Permanent ("unattended") access is only ever set up under a separate, explicit agreement.

The connection is encrypted end-to-end, you can watch everything we do and end the session at any time, and we only access what is needed for the task. Before starting, please make sure a current backup of your important data exists and close anything confidential or unrelated. See "Remote support: data protection and your rights" in the Help Center for the full detail.
