Microsoft Office 2021 Professional Plus – Phone activation

Office 2021 Professional Plus with phone activation

This variant of Office 2021 Professional Plus is activated by telephone. The designation describes the method of activation and does not involve any additional licence rights. In terms of content, it is the edition that Microsoft lists as Office LTSC Professional Plus 2021: Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher and Skype for Business for Windows PCs. The edition is aimed at users and companies that deliberately stay with Office 2021, for example because presentation templates, mail merges or Access applications are tailored to this version.

Presenting, writing and communicating

PowerPoint 2021 extends the Record Slide Show feature: the presenter's camera image, ink input and laser pointer movements are now also recorded. This makes it possible, for example, to provide an induction for new employees as a video. Ink drawings can be replayed or rewound as an animation, and the Reading Order determines the sequence in which a screen reader reads out the elements of a slide.

In Word 2021, dark mode darkens not only the ribbon but also the page area. During proofreading, Line Focus hides everything except one, three or five lines. The Accessibility Checker reports content in the status bar of Word, Excel and PowerPoint that is difficult to access for people with disabilities. Outlook 2021 translates emails into more than 70 languages, finds messages via Instant Search above the ribbon and allows you to annotate images in an email with ink.

Excel, Access and Publisher

Excel 2021 brings XLOOKUP for finding values in tables as well as dynamic arrays: a formula with FILTER or SORT outputs a complete list of results that adjusts automatically when the source data changes. In Access 2021, databases are built with tables, queries, forms and reports; the Linked Table Manager manages linked data sources in a central place. Publisher is used to design flyers, notices and brochures. Office LTSC 2021 no longer installs the Teams client.
