Outlook PST – keep mail, calendar and contacts in local data files.

What does Microsoft Office 2019 Professional Plus do?

It installs the full Pro Plus desktop suite on a Windows PC and gives you the Office application set as Microsoft froze it in 2019. You get Word, Excel, PowerPoint, Outlook, OneNote, Publisher, Access and Skype for Business installed locally, so all editing, file storage and printing happen on your own machine. Compared with the Standard edition, Pro Plus adds Access for relational databases and Skype for Business for legacy enterprise communication. New features added later to Microsoft 365, such as Copilot, dynamic arrays in Excel, or co-authoring on OneDrive, are not back-ported to Office 2019.

Who is Office 2019 Professional Plus best suited for?

It fits users and IT teams that need a stable, frozen Office version that keeps working without a subscription. Typical cases are accounting workstations running long-lived Excel models, technical writers who rely on Word with local templates, and small organisations that still depend on Access databases or Publisher print files. Because the feature set never changes, training material, macros and VBA projects stay valid for the whole supported lifetime. Users tied to Microsoft Teams collaboration or live cloud co-authoring will not find those workflows in this edition.

How does Office 2019 Pro Plus differ from Office 2019 Standard, Office 2021 and Microsoft 365?

Pro Plus differs from Office 2019 Standard by including Access and Skype for Business in addition to Word, Excel, PowerPoint, Outlook, OneNote and Publisher. Compared with Office 2021 Pro Plus, the 2019 release lacks features added later, including dynamic array functions (XLOOKUP, FILTER, SORT), LET, the modern Outlook search index, and improved accessibility tooling. Compared with Microsoft 365 Apps for Enterprise, Office 2019 receives only security fixes – no new features, no Copilot, no continuous feature updates. The trade-off is a stable, unchanging environment that does not depend on an active subscription.

What technical limitations should users know before buying?

Office 2019 receives security updates only – Microsoft confirmed no new features have been added since its release. Microsoft Teams, Copilot, dynamic array functions in Excel (XLOOKUP, FILTER, LET), and live cloud co-authoring are not part of this edition. Skype for Business 2019 is included but the Skype for Business Online service was retired by Microsoft in July 2021, so it is mainly useful in on-premises Skype for Business Server environments. Mainstream support has ended; extended support and security updates continue until 14 October 2025.

Which Windows versions does Office 2019 Professional Plus support?

Microsoft officially supports Office 2019 on Windows 10 and Windows Server 2019. It is not supported on Windows 7, Windows 8 or Windows 8.1, and Microsoft does not list Windows 11 as a supported platform for Office 2019, so users planning a Windows 11 upgrade should check current Microsoft guidance before installing. Outlook 2019 supports Exchange 2013 SP1 and later, including Exchange Online via MAPI/HTTP. There is no macOS version of Office 2019 Professional Plus; only Office 2019 Home & Business or Standard variants exist for Mac.

Are Microsoft Teams and OneDrive cloud collaboration included?

No. Microsoft Teams is not part of Office 2019 Professional Plus and must be obtained separately. The included communication client is Skype for Business 2019, which targets on-premises Skype for Business Server deployments. The OneDrive desktop sync client can be installed independently on Windows, but the integrated cloud co-authoring, version history and SharePoint workflows that Microsoft 365 Apps offer are not part of this perpetual edition. Files stay local unless you set up sync yourself.

Perpetual Office vs Microsoft 365
Why a one-time Office purchase can be the better choice for users who do not need the Microsoft 365 cloud features.

What should users check before choosing Office 2019 Professional Plus?

Confirm that you actually need Access or Skype for Business, since these are the two applications that justify Pro Plus over the Standard edition. Check that your file partners are not on Microsoft 365 features your version cannot read or write back faithfully, especially LAMBDA functions and dynamic arrays in Excel. If your organisation has moved to Teams for chat and meetings, the included Skype for Business client will not connect to a Teams tenant. Also verify your target operating system: Office 2019 is built for Windows 10 / Windows Server 2019 and not for Windows 11.

Frequently asked questions about Microsoft Office 2019 Professional Plus

Is Microsoft Office 2019 Professional Plus a one-time purchase?

Yes. It is a perpetual desktop release of Office, not a subscription. The included version of each application stays at the 2019 feature level and only receives Microsoft security updates until 14 October 2025.

Does Office 2019 Professional Plus include Microsoft Access?

Yes. Access is one of the applications that distinguishes Pro Plus from Office 2019 Standard. You can build local relational databases, design forms and run queries on Windows without needing a separate Access license.

Will Office 2019 still receive updates?

Mainstream support ended on 10 October 2023. Microsoft continues to provide security updates through the extended support phase, which ends on 14 October 2025. No new features will be added during that period.

Can Office 2019 open files created in Microsoft 365 or Office 2021?

Yes, the file formats (.docx, .xlsx, .pptx) remain compatible. However, features introduced after 2019 – such as dynamic array results, LAMBDA, or Loop components – may appear as static values, placeholder text, or be unavailable for editing when opened in Office 2019.

Legal Information About Our Products

keys.express and keys.discount are online platforms for product keys. The product keys available in our shops for Windows and other software are inexpensive, secure, legal and come with an activation guarantee.

Below you will find the most important legal information about our products.

Unused and Non-Activated Product Keys

We offer exclusively unused and non-activated product keys. The keys have never been redeemed for activation and are fully available to the purchaser for the first-time activation of the respective product. A key that has already been redeemed could no longer be used for a new activation and is therefore not offered by us.

Trading in these product keys is permissible in the European Union and in Switzerland under current case law, provided that the necessary conditions are met. These conditions are as follows:

• The software must originally have been placed on the market with the consent of the rightholder within the territory of the EU, another contracting state of the EEA, or Switzerland by way of sale.
• The license for the software must have been granted in return for the payment of a fee intended to enable the rightholder to obtain remuneration corresponding to the economic value of the copy of the software.
• The rightholder must have granted the first acquirer the right to use the software permanently (for an unlimited period).
• Any improvements and updates that the subsequently downloaded computer program has compared to the originally downloaded one must be covered by a maintenance agreement concluded between the rightholder and the first acquirer.
• The original licensee must have made their own copies unusable.

This trade is legally permissible because the underlying license was already placed on the market with the consent of the rightholder within the EU/EEA or Switzerland in return for appropriate remuneration. As a result, the so-called principle of exhaustion has taken effect, which permits the resale of individual product keys — in particular those originating from volume license agreements. Microsoft or the respective software provider has already received appropriate remuneration for this.

keys.express and keys.discount ensure that the aforementioned conditions are met and that the lawful use of the software is guaranteed. The requirements arising from European legislation are also observed in Switzerland.

Important note: The acquisition of a product key through the transmission of a combination of numbers and letters in digital form does not, in itself, constitute a license for the lawful use of the program. The license only arises from the respective installation and the associated acceptance of the manufacturer's terms of use.

Overview of the Most Important Legal Information

• We offer unused, non-activated product keys for the activation of the respective computer programs. The key alone is not yet a license.
• The license only arises from the respective installation and the resulting acceptance of the terms of use. These terms of use govern the right to use the software between you and the respective manufacturer.
• The principle of exhaustion has, as a rule, taken effect — i.e. the license is "used up" — as soon as it was lawfully placed on the market for the first time. The products concerned are software placed on the market for unlimited-time use in the form of an activatable product key with the option to download the program. Microsoft or the respective software provider has received appropriate remuneration for this.
• You gain access to particularly attractively priced product keys from volume license agreements, which are to be treated legally in the same way as parts of volume licenses upon first acquisition.
• The software itself is always the same original software that is also obtained through official download channels or manufacturer sources. You are therefore not paying for a different or inferior version, but for a valid activation key or a corresponding license.
• All brand names and brand logos are registered trademarks, whose use here serves solely for product description — the ownership rights lie with the respective trademark holder.
