Unlike Microsoft 365, this version only receives updates for a fixed period of time. This support ends on <span class=\"s1\"><b>13 October 2026<\/b><\/span>. After this date, Microsoft will no longer provide security updates, bug fixes or technical support.<\/p><p class=\"p1\">For companies and organisations, this means that anyone who continues to use Office 2021 after this date will be working with software that is no longer supported.<\/p><p class=\"p3\">\u00a0<\/p><h4><b>What does the end of support mean in concrete terms?<\/b><\/h4><p class=\"p1\">Official maintenance by Microsoft ends with the End of Service. This affects all applications in the suite, including<\/p><ul><li><p class=\"p1\">Word<\/p><\/li><li><p class=\"p1\">Excel<\/p><\/li><li><p class=\"p1\">PowerPoint<\/p><\/li><li><p class=\"p1\">Outlook<\/p><\/li><li><p class=\"p1\">OneNote<\/p><\/li><\/ul><p class=\"p1\">The programmes will continue to work on the existing system, but without further updates or support from the manufacturer.<\/p><p class=\"p1\"><strong>In concrete terms, this means<\/strong><\/p><ul><li><p class=\"p1\"><span class=\"s1\"><b>No more security updates<\/b><\/span> for newly discovered vulnerabilities<\/p><\/li><li><p class=\"p1\"><span class=\"s1\"><b>No bug fixes<\/b><\/span> in the event of problems or software errors<\/p><\/li><li><p class=\"p1\"><b>No technical support<\/b><span class=\"s1\"> by Microsoft<\/span><\/p><\/li><li><p class=\"p1\"><b>No adaptations to new operating systems or services<\/b><\/p><\/li><\/ul><p>\u00a0<\/p><p class=\"p3\">\u00a0<\/p><h4><b>What risks arise afterwards?<\/b><\/h4><p class=\"p1\">The continued operation of software that is no longer supported entails several risks.<\/p><p class=\"p4\"><b>Security gaps<br \/><\/b><b><\/b>New vulnerabilities are no longer closed. This increases the risk of malware or targeted attacks.<\/p><p class=\"p4\"><b>Compatibility problems<br \/><\/b><b><\/b>There may be restrictions or functional problems with future Windows versions or new cloud services.<\/p><p class=\"p4\"><b>Lack of manufacturer support<br \/><\/b><b><\/b>In the event of technical problems, there are no more official updates or support requests.<\/p><p class=\"p4\"><b>Compliance and IT guidelines<br \/><\/b><b><\/b>Many companies and regulated industries require the use of supported software versions.<\/p><p class=\"p3\">\u00a0<\/p><h4><b>What alternatives are there?<\/b><\/h4><p class=\"p1\">Organisations should plan in good time how they want to continue working after the end of support.<\/p><p><b><br \/>Microsoft 365<\/b><\/p><p class=\"p1\">The most commonly used solution is to switch to <span class=\"s1\"><b>Microsoft 365<\/b><\/span>. This is a subscription model with constantly updated Office applications.<\/p><p class=\"p1\"><strong>Advantages:<\/strong><\/p><ul><li><p class=\"p1\">Always up-to-date functions<\/p><\/li><li><p class=\"p1\">Ongoing security updates<\/p><\/li><li><p class=\"p1\">Collaboration in real time<\/p><\/li><li><p class=\"p1\">Integration with OneDrive, SharePoint and Microsoft Teams<\/p><\/li><\/ul><p><b><br \/>New Office purchase version<\/b><\/p><p class=\"p1\">Alternatively, a newer purchase version such as <span class=\"s1\"><b>Office 2024<\/b><\/span> can be used. This offers a longer support period, but also without continuous function updates.<br \/><br \/><\/p><h4><b>When should you start planning?<\/b><\/h4><p class=\"p1\">A migration should not be started just before the end of support. In many companies, several points need to be checked before a migration:<\/p><ul><li><p class=\"p1\">Existing macros and add-ins<\/p><\/li><li><p class=\"p1\">Compatibility with specialised applications<\/p><\/li><li><p class=\"p1\">Licence strategy<\/p><\/li><li><p class=\"p1\">Rollout and training of employees<\/p><\/li><\/ul><p class=\"p1\">Depending on the size of the company, a complete changeover can take several months.<\/p><p class=\"p1\"><br \/>With the <span class=\"s1\"><b>End of Service of Microsoft Office 2021 on 13 October 2026<\/b><\/span> official support for this version ends. After that, there will be no more security updates or bug fixes.<\/p><p class=\"p1\">Companies should therefore check at an early stage whether a switch to <span class=\"s1\"><b>Microsoft 365 or a newer version of Office<\/b><\/span>makes sense.
