When the Office bundle pays off"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\"><strong>Short answer:<\/strong> Copilot wins on integration, not on answer quality. If your work happens in Outlook, Teams and Excel and your filing is in decent shape, that&#8217;s a strong argument. If your work consists of documents, analysis and precise wording, it isn&#8217;t one. And the most common question behind all this, &#8220;We already have Microsoft 365, isn&#8217;t that enough?&#8221;, isn&#8217;t answered by price, but by your SharePoint filing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>As of: August 2026. Prices and features in this market change fast; all figures were checked on the providers&#8217; own sites on the day of publication.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Disclosure:<\/strong> I make my living from consulting and training around Claude. That&#8217;s why I start with the cases where Copilot is the better choice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The key points<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The advertised price is a surcharge:<\/strong> Copilot Business costs \u20ac15.60 (promo until 09\/30\/2026, then \u20ac18.20) <em>on top of<\/em> the Microsoft 365 license.<\/li>\n<li><strong>Copilot&#8217;s value depends on your filing.<\/strong> Unstructured SharePoint delivers unstructured results, or surfaces things to the wrong people.<\/li>\n<li><strong>Claude is independent of your office software<\/strong> and stronger on long documents and exact instructions.<\/li>\n<li><strong>Neither trains on your content:<\/strong> Microsoft under Enterprise Data Protection, Claude on its business plan.<\/li>\n<li><strong>A clean-up project before rolling out Copilot<\/strong> is the rule, not the exception. Budget for it.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How I compare<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Seven criteria from consulting practice instead of benchmark scores: real workload, context connectivity, data protection, rollout, total cost, exit cost, pace of development. Reasoning in the <a href=\"https:\/\/pletzenauer.com\/en\/2026\/07\/30\/how-i-evaluate-ai-tools\/\">evaluation framework<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Copilot really costs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is where most of the confusion comes from, so the numbers first, in full.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Option<\/th><th>yearly<\/th><th>monthly<\/th><\/tr><\/thead><tbody>\n<tr><td>Copilot Business (add-on)<\/td><td>\u20ac15.60 promo \u00b7 regularly \u20ac18.20<\/td><td>\u20ac21.84<\/td><\/tr>\n<tr><td>Business Standard <em>with<\/em> Copilot<\/td><td>\u20ac20.36<\/td><td>\u20ac24.43<\/td><\/tr>\n<tr><td>Business Premium <em>with<\/em> Copilot<\/td><td>\u20ac27.73<\/td><td>\u20ac33.28<\/td><\/tr>\n<tr><td>Claude Team (for comparison)<\/td><td>$20\/seat<\/td><td>$25\/seat<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Three things you need to know when doing the math. First: the \u20ac15.60 promo price only applies to annual commitments signed by <strong>September 30, 2026<\/strong>. After that, \u20ac18.20. Second: the add-on requires a base license, Microsoft 365 Business Basic, Standard, Premium or Apps for Business. So the add-on price is never the total price. Third: monthly billing costs roughly a 20 percent surcharge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you&#8217;re already paying for Business Standard and adding Copilot on top, you land at around \u20ac20 per person per month, not \u20ac15.60. That&#8217;s still competitive, but it&#8217;s a different number than the one on the banner ad.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Copilot wins<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When the work happens in the inbox and the calendar.<\/strong> The strongest real-world use case I see is unspectacular: meeting summaries in Teams, catching up after time off, drafts written directly in Outlook. These aren&#8217;t dazzling capabilities, but they land exactly where people already sit. A tool you don&#8217;t have to open separately gets used more often, and usage beats capability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you don&#8217;t want to bring in a second vendor.<\/strong> One contracting party, one invoice, one user management system, one data protection process. For small IT departments that&#8217;s a genuine argument, and I don&#8217;t consider it laziness, I consider it good operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When your filing is in decent shape.<\/strong> Then, and only then, does Copilot play its actual trump card: it knows your documents, your emails, your appointments, without you uploading anything. That&#8217;s the difference between a very well-read stranger and a colleague who knows the company.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When compliance requirements are closely tied to Microsoft.<\/strong> Enterprise Data Protection, EU Data Boundary, extended data residency, ISO\/IEC 27018, if your auditors know and accept these terms, you save yourself a discussion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Claude wins<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>With long documents and precise text work.<\/strong> Working through contracts, evaluating tenders, condensing expert reports, producing standardized wording, that&#8217;s where I see the clearest difference in projects. Copilot is built for assistance in the flow of everyday office work, not for focused text work on one big document.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When instructions need to be followed exactly.<\/strong> &#8220;This structure, these terms, don&#8217;t invent anything.&#8221; For anything that gets checked afterward, that saves measurable rework.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you want to connect your own line-of-business applications.<\/strong> The <a href=\"https:\/\/pletzenauer.com\/en\/2025\/07\/05\/model-context-protocol-mcp-explained-n8n-example\/\">Model Context Protocol<\/a> lets you connect systems Microsoft has nothing ready-made for. Inventory management, industry software, your own databases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When your filing is a mess.<\/strong> That sounds paradoxical, but it&#8217;s the practical consequence: a tool you deliberately feed the right documents delivers usable results faster in a disorderly environment than one that automatically searches everything, including the twelve outdated quote versions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The point almost everyone underestimates: your filing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Copilot is only as good as what it can access. That&#8217;s not a side note, it&#8217;s the core of the decision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two problems show up in almost every business I see. The first is disorder: if SharePoint holds five versions of the same quote and none is marked as current, Copilot cites whichever one it finds. The second is more uncomfortable: permissions that have grown organically over years. Copilot respects existing access rights, but that&#8217;s exactly what exposes what someone technically has access to without ever having noticed. The classic case is the folder with salary data that someone shared with &#8220;everyone in the company&#8221; six years ago because it needed to happen fast.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This isn&#8217;t a Copilot bug. It just makes visible what was already true. But it means: <strong>budget for a clean-up project before you roll out.<\/strong> Review permissions, archive outdated filings, mark valid documents. In businesses with organically grown filing systems, that&#8217;s typically a matter of weeks, and this line item is missing from every sales brochure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Data protection: the two aren&#8217;t far apart here<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Under Enterprise Data Protection, Microsoft commits that prompts and responses stay within the Microsoft 365 service boundary and are <strong>not used to train the language models<\/strong>, with support for GDPR, ISO\/IEC 27018, the EU Data Boundary and extended data residency. One detail worth knowing: prompts and responses are logged and subject to your own retention policies, which is an advantage from a compliance standpoint and a piece of information employees deserve to be told.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With Claude, the business plan likewise involves no training on your content. For EU customers, according to the vendor, the contracting entity is Anthropic Ireland Limited. The difference lies less in the commitment than in the contract landscape: with Microsoft you already have a contract; with Anthropic, you add one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practical assessment, not legal advice. I compare the details in the <a href=\"https:\/\/pletzenauer.com\/en\/2026\/09\/08\/ai-gdpr-vendor-comparison\/\">GDPR comparison<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">&#8220;We already have Microsoft 365, isn&#8217;t that enough?&#8221;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This question comes up in almost every first conversation. My honest answer, in three parts:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yes<\/strong>, if your work genuinely happens in Outlook, Teams and Excel, your filing is well maintained, and you&#8217;re mainly looking for everyday assistance. Then a second vendor is a complication with no payoff.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No<\/strong>, if your most valuable work is focused text work. Contracts, concepts, technical writing, high-value proposals. There the quality gap is large enough that a second tool pays for itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Not yet<\/strong>, if your filing is a mess. Then Copilot mostly buys you work. Clean up first, that pays off regardless of any AI decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What you need to settle regardless of the tool<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Review permissions<\/strong>: before rollout, not after.<\/li>\n<li><strong>Mark valid documents<\/strong> and archive outdated ones.<\/li>\n<li><strong>A one-page policy<\/strong> that also addresses personal use.<\/li>\n<li><strong>Communicate that prompts are logged<\/strong>: before someone else finds out.<\/li>\n<li><strong>A named point of contact<\/strong> for the first few weeks.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Can we license Copilot for only part of the workforce?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, the add-on is booked per user. In practice, that&#8217;s exactly the sensible path: equip the people whose work genuinely happens in the inbox first, and decide after three months, based on actual usage, whether more should be added.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is the promo price gone after September 30?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The promo price applies to annual commitments signed by then. Whether and for how long it carries over on running contracts is a question for your Microsoft partner, and one you should get answered in writing before you sign. Don&#8217;t let an expiring promo price push you into a decision you haven&#8217;t actually made yet on the merits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can we use Copilot and Claude in parallel?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can, and in some companies that&#8217;s the right answer. Copilot for the broad workforce, Claude for the department doing demanding text work. The precondition is a written rule for what&#8217;s used for what. More on that in <a href=\"https:\/\/pletzenauer.com\/en\/?p=1853\">One AI tool, or several?<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does a Copilot rollout realistically take?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Technical activation is a matter of hours. Cleaning up filing and permissions takes weeks in organically grown environments, and training needs two to three guided hours per person. If you&#8217;re only planning for the activation, you&#8217;re planning for the smallest part.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What if we have Microsoft 365 but barely use it?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Then Copilot&#8217;s strongest argument disappears. If your people actually work in entirely different programs and Microsoft 365 only runs mail and file storage, you&#8217;re paying for an integration that doesn&#8217;t land for you. In that case, a standalone tool is usually the more honest choice.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Copilot wins on integration, not answer quality.
