What does Microsoft Office 2016 Professional Plus do?

Office 2016 Professional Plus is a locally installed productivity suite for writing documents, building spreadsheets, designing slides, and managing email and contacts. It includes Access for desktop databases and Publisher for newsletters, flyers, and print-ready layouts, which the smaller Home & Business and Home & Student editions do not contain. Excel 2016 added six new chart types including Waterfall, Treemap, and Histogram, and integrated Power Query directly into the ribbon as Get & Transform. Outlook 2016 introduced the Clutter folder and faster search through a new MAPI/HTTP transport. The suite is the perpetual desktop version, so files stay on the local machine and there is no required online sign-in to use the core applications.

Who is Office 2016 Professional Plus best suited for?

It fits users and small offices that need Access database files or Publisher layouts and want to keep working with a one-time purchase instead of Microsoft 365. A typical case is an office that maintains an existing .accdb database or .pub flyer template built in an earlier Office version and needs an editor that opens those formats natively, since neither Access nor Publisher exists in Office 2016 Home & Business. The suite also suits users with limited or offline connectivity, because the desktop apps do not require continuous cloud authentication for core editing. Outlook 2016 supports POP, IMAP, Exchange, and Microsoft 365 mailboxes, so it remains usable as a standalone mail client. Users who only need Word, Excel, PowerPoint, and Outlook can save money by choosing Home & Business instead.

How does Office 2016 Professional Plus differ from Home & Business and Standard?

Professional Plus is the most complete Office 2016 edition and is the only one that includes both Access and Skype for Business alongside the core apps. Home & Business contains Word, Excel, PowerPoint, OneNote, and Outlook but no Access, Publisher, or Skype for Business. Office 2016 Standard adds Publisher and Skype for Business to that set but still leaves out Access. The table below shows the exact application coverage across the three editions so buyers can match the edition to the workflow they actually need.

What technical limitations should users know before buying?

Office 2016 reached the end of extended support on October 14, 2025, which means Microsoft no longer ships security updates or bug fixes for the suite. Connection to Microsoft 365 services such as Exchange Online mailboxes was already blocked for Office 2016 clients from October 2023 onward. The suite does not include Microsoft Teams, OneDrive cloud sync, or the AI Copilot features that ship only with Microsoft 365 and Office 2024. Skype for Business Online itself was retired by Microsoft in July 2021, so the included Skype for Business 2016 client is only useful against on-premises Skype for Business Server installations. Users who rely on hosted Exchange or modern collaboration should plan for a newer edition or Microsoft 365.

Which file formats does Office 2016 Professional Plus support?

Word, Excel, and PowerPoint 2016 use the Office Open XML formats .docx, .xlsx, and .pptx by default and still open the older .doc, .xls, and .ppt binary formats. Word 2016 can save and export documents directly as PDF without an add-in. Excel 2016 can import from CSV, XML, JSON, text, ODBC, and many web sources through Power Query, and Access 2016 works with .accdb and the older .mdb database formats. Outlook 2016 stores local data in .pst and .ost files and can import .msg, .eml, and .ics calendar files. Publisher 2016 opens .pub files and can export to PDF, XPS, and packaged print-ready formats.

What makes Office 2016 Professional Plus useful in daily work?

The combination of Access and Excel covers the gap between flat spreadsheets and structured data without needing a separate database product. A small office can keep customer records in an Access table, link the table into Excel through Power Query, and refresh reports without retyping data. PowerPoint 2016 introduced the Morph transition, which animates between two slides when they share objects, removing the need to build per-element animations for product diagrams or before/after layouts. The Tell Me search box in the ribbon finds commands by name, which shortens onboarding for occasional users. Real-time co-authoring in Word 2016 works on documents stored in SharePoint or OneDrive for Business, but only when those services are still reachable.

What should users check before choosing Office 2016 Professional Plus?

Confirm that the existing workflow does not depend on hosted Microsoft 365 services, since Office 2016 clients are blocked from Exchange Online and the suite no longer receives security patches after October 2025. Check whether Access and Publisher are actually needed, because Office 2016 Home & Business is significantly cheaper and covers Word, Excel, PowerPoint, OneNote, and Outlook. Verify the underlying Windows version, since Office 2016 mainstream support requires Windows 7 SP1 or newer and does not officially support Windows 11. Open one existing .accdb, .pub, or .pst file in a trial before migrating, to confirm the file format opens cleanly. Buyers who need ongoing security updates and modern Outlook connectivity should look at Office 2021 or Office 2024 instead.

Frequently asked questions about Microsoft Office 2016 Professional Plus

Is Microsoft Teams included in Office 2016 Professional Plus?

No. Teams was first released in March 2017, after Office 2016 shipped, and is not part of any Office 2016 edition. The Professional Plus suite includes the older Skype for Business 2016 client instead. Users who need Teams must install it separately or move to Microsoft 365.

Does Office 2016 Professional Plus still receive security updates?

No. Microsoft ended extended support for Office 2016 on October 14, 2025, so no further security patches, bug fixes, or technical assistance are issued. The applications continue to run, but newly discovered vulnerabilities will not be fixed. This is the main reason to evaluate Office 2021 or Office 2024 for new installations.

Can Outlook 2016 still connect to Microsoft 365 mailboxes?

No. Microsoft blocked connections from Office 2016 clients to Exchange Online starting in October 2023, so Outlook 2016 cannot reliably connect to a Microsoft 365 hosted mailbox. It still works with on-premises Exchange Server, IMAP, and POP accounts. Users with Microsoft 365 mail need a newer Outlook version.

Is Office 2016 Professional Plus a one-time purchase desktop version?

Yes. It is a perpetual desktop version of Office, not a subscription, and the applications are installed locally on Windows. There are no cloud-only features in the suite itself, and core editing in Word, Excel, PowerPoint, and Outlook runs without requiring a continuous internet connection.

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.
