About this licence
Microsoft Skype for Business 2019 — Enterprise Unified Communications for On-Premises Control
Maintain complete sovereignty over your organisation's real-time communications with a genuine Microsoft Skype for Business 2019 client license. This is the definitive unified communications client engineered specifically for enterprises that operate their own on-premises Skype for Business Server infrastructure. While the industry shifts towards cloud-only models, this retail license empowers regulated sectors—government, defence, financial services, and healthcare—to retain absolute control over their data, meeting stringent GDPR, HIPAA, and national compliance mandates without compromise.
Skype for Business 2019 is not merely a chat application; it is a full-fledged communications hub that integrates instant messaging with rich presence, enterprise-grade voice (VoIP) with PSTN connectivity, multi-party HD video conferencing for up to 250 participants, and intelligent screen sharing. It bridges the gap between legacy telephony systems and modern collaboration, allowing your workforce to see real-time availability, escalate chats to calls, and host structured virtual meetings with integrated PowerPoint sharing, whiteboarding, and Q&A moderation. This is a one-time purchase, perpetual license designed for Windows 10 and Windows 11 environments, providing a stable, long-term communications platform that you control entirely.
Key features and benefits
Complete data sovereignty with on-premises deployment: All instant messages, call records, uploaded content, and meeting recordings are processed and stored on your own servers. This is essential for organisations bound by strict regulatory frameworks that prohibit data from leaving organisational boundaries, ensuring legal compliance and internal security oversight.
Intelligent presence and instant messaging: Real-time presence indicators show exactly who is available, busy, in a meeting, or away before you even send a message. This reduces communication friction and eliminates the guesswork of colleague availability, streamlining decision-making across distributed teams.
Enterprise Voice (VoIP) with full telephony integration: Replace or supplement traditional PBX phone systems with software-based telephony. Features include call forwarding, simultaneous ring, voicemail with transcription, executive call delegation, and response groups for contact centre scenarios, unifying voice communications into a single client.
Multi-party HD video and content collaboration: Host structured video conferences with gallery view for up to 250 participants. Go beyond simple video with integrated PowerPoint sharing, collaborative whiteboarding, live polling, and moderated Q&A sessions, making virtual meetings as interactive as physical workshops.

Persistent meeting recording for compliance: Capture the full meeting context—audio, HD video, screen shares, and instant messages—in a single recording. This is critical for compliance archival, training purposes, or allowing absent team members to review decisions and discussions asynchronously.
Native Outlook integration for one-click scheduling: Schedule a Skype meeting directly from the Outlook calendar ribbon. Invitations automatically embed a join link, and calendar-based presence updates your status to 'In a Meeting', synchronising your communications tool with your daily workflow.
Hybrid deployment pathway to Microsoft Teams: Operate a mixed environment where on-premises Skype for Business users communicate seamlessly with cloud-based Microsoft Teams users. This provides a controlled, gradual migration path without forcing a disruptive, all-at-once transition.
Enhanced firewall traversal and bandwidth management: The 2019 client introduces improved network resilience for remote workers. Sophisticated bandwidth management maintains call quality even on constrained connections, while better firewall traversal simplifies connectivity from hotels, home offices, or client sites without complex VPN configurations.
Dial-in audio conferencing with DTMF controls: External participants without a client can join meetings via a traditional phone line. They can use touch-tone (DTMF) commands to mute, unmute, or access other in-meeting controls, ensuring inclusivity for all stakeholders.
Modernised user interface aligned with Office: The client features an updated visual language consistent with the wider Office suite. This reduces the learning curve for users already familiar with Microsoft productivity tools, accelerating user adoption across the organisation.

This retail license allows for reinstallation on the same device should you need to rebuild your system, ensuring long-term operational continuity.

FAQ — frequently asked questions
Is this a subscription or a one-time purchase?
This is a one-time purchase for a perpetual license. You pay once and have the right to use the software indefinitely on the licensed device, unlike Microsoft 365 subscriptions which require recurring payments.
What is the difference between a Retail and an OEM license?
A Retail license, like this one, is transferable to a new device if the original one is decommissioned and offers greater flexibility for reinstallation. An OEM license is typically pre-installed by a manufacturer and is permanently tied to the first computer it is activated on.
How fast will I receive my license key?
Your license key is delivered automatically via email immediately after payment confirmation. In most cases, this takes less than 60 seconds, allowing you to start the download and installation process almost instantly.
Is this a genuine, legal Microsoft license?
Absolutely. Lizensa sources all licenses from authorised European distributors. You receive a verified, legally compliant license key and a full VAT invoice, ensuring you are fully covered for software asset management audits.
What if I have trouble activating the product?
Activation issues are rare, but if one occurs, our free multilingual technical support team is ready to help. We can guide you through manual activation steps or help diagnose any conflicts preventing successful activation.
Can I reinstall or transfer this license to a new computer?
As a Retail license, you can reinstall the software on the same device as many times as needed. If you decommission the original device, you are generally permitted to transfer the license to a new computer, providing flexibility that OEM licenses do not offer.
Does this license work in my country?
Yes, this license is valid for activation and use across all 27 member states of the European Union. It is a pan-European license designed for the EU market.
What payment methods do you accept?
Our checkout is powered by Stripe and accepts a wide range of payment methods including major credit cards (Visa, Mastercard), SEPA bank transfers, iDEAL, BLIK, and Google Pay, ensuring a secure transaction.
Do you provide a VAT invoice for business purchases?
Yes, a detailed VAT invoice is provided with every purchase. For B2B customers within the EU, the reverse-charge mechanism can be applied to the transaction, simplifying your accounting.
What is your refund policy?
We offer a 14-day right of refund in accordance with EU consumer protection regulations. If you have not activated the license and it is unused, you can request a full refund within this period.
Does Skype for Business 2019 work without a server?
No, the Skype for Business 2019 client requires a connection to an on-premises Skype for Business Server 2019 deployment. It is an enterprise client designed to connect to your organisation's own infrastructure, not a standalone consumer application.
Can this client connect to Microsoft Teams users?
Yes, it supports hybrid deployments. When configured by your IT administrators, the Skype for Business 2019 client can communicate seamlessly with users in your organisation who are using Microsoft Teams, facilitating a gradual migration path.
