What is Microsoft Copilot and what is it good for at work?
Microsoft Copilot is an AI assistant for asking questions, creating content and researching, available as an app and on the web, and also built into Microsoft 365 apps such as Word, Excel, PowerPoint, Outlook and Teams. Microsoft's documentation now uses Microsoft Copilot for what was called Microsoft 365 Copilot, and Microsoft Copilot Chat for what was Microsoft 365 Copilot Chat, so you will see both names during the transition.
The important distinction is the account. Microsoft says the Copilot app accepts a personal account, a work or school account, or both, and keeps them separate: data from the work experience does not flow into the personal one, or the reverse. With a work account, your organisation's security, privacy and compliance controls apply, and Copilot can draw on organisational content such as emails, files, chats and meetings that you already have permission to see. With a personal account, it is a general assistant for your own tasks.
How do I get started with Microsoft Copilot?
For work, open Copilot in a browser and sign in with your work or school account, or use it inside Teams and Outlook. Microsoft's getting-started page says Copilot Chat is available to users with an eligible Microsoft 365 subscription, and some features depend on your licence and your organisation's settings, so ask IT what you have. A Work or Personal label beside your profile shows which account you are in, and the account switcher moves between them.
For personal use, sign in to the Copilot app with a Microsoft account. Microsoft says personal users get free chat, image creation and file uploads within limits, with higher limits on Microsoft 365 subscriptions.
Your first useful work prompt references real context you are allowed to use. Type a forward slash to pick a file, person or meeting, for example: 'Summarise /[file name] in five bullet points for my manager and list any decisions it says are still open.'
What is a good 10-minute Microsoft Copilot starter exercise?
Use a fictional 40-person freight company, Kestrel Freight. Create a short practice document in your own OneDrive called Depot move notes, with invented details: the Leeds depot moves on a weekday in spring, two vans need new parking permits, the customer notice has not been sent, and the IT cut-over date is not agreed.
Minute 1 to 3: in Copilot Chat with your work account, reference the document with a forward slash and ask for a status update for the operations director, under 120 words, with a separate list of open items. Minute 4 to 6: ask Copilot which statements in its update come directly from the document and which it inferred. Minute 7 to 8: ask for a version as a three-row table: done, in progress, not started. Minute 9 to 10: compare the table to your notes and correct anything that slipped from not agreed to agreed.
If you only have a personal account, paste the invented notes instead of referencing a file. The exercise still works, but you lose the grounding in your own work content, which is the main reason businesses buy the work version.
How do I get better results from Microsoft Copilot?
Copilot at work is only as good as the content it can reach and the clarity of your request. These techniques come from Microsoft's own pages.
Be clear, concise and specific
Microsoft's guidance is to state your goal plainly, then follow up to refine rather than writing one enormous prompt.
Reference content with a slash
Type / and choose a file, person or meeting so Copilot works from the right source instead of guessing which document you mean.
Know when Work IQ is on
Microsoft says that with Work IQ on, the default, Copilot uses organisational data such as files, email and Teams meetings; with it off, it answers from the web and its training only. Pick the mode that matches the question.
Use the app you are working in
Copilot inside Word, Excel or PowerPoint works with that file and its context, which is often faster than copying content into chat.
What should I not paste into Copilot, and what does Microsoft say about data?
Use your work account for work content and follow your employer's AI policy. Never move company files into a personal Copilot account to get around a licence gap.
For work accounts, Microsoft's data, privacy and security page states that prompts, responses and data accessed through Microsoft Graph are not used to train foundation models, that Copilot only surfaces organisational data a user has at least view permission for, and that admins can set retention policies for Copilot interactions with Microsoft Purview. Users can delete their Copilot activity history from the My Account portal. That permission point matters: if a sensitive folder is shared too widely, Copilot can surface it to everyone with access.
For personal accounts, Microsoft's Copilot privacy controls page describes settings to opt out of training on conversation activity and voice conversations, says opting out does not exclude conversations from other product improvements, and says conversation history is kept for 18 months unless you delete it. Microsoft notes that page applies to the older app version, so check the settings in your current app.
Where does Microsoft Copilot fall short?
Microsoft says generative AI responses are not always factual and that users should use their judgement before sending output to others. Grounding in your files reduces invention but does not remove it, and Copilot can faithfully summarise a document that is itself out of date.
Availability is the other limit. Features vary by licence, platform and admin settings, and the naming transition means help articles, menus and colleagues may use different names for the same thing.
How does Tosheo.ai teach Microsoft Copilot inside a role path?
For Microsoft 365 teams, Tosheo.ai paths put Copilot tasks in the context of each role: a finance assistant summarising a month-end checklist, a recruiter drafting interview questions from a job description, or a customer support lead turning a long thread into an escalation note. Lessons use fictional material so nothing real needs to leave your tenant.
Each lesson takes 10 to 15 minutes and finishes with a task in Copilot, marked against a visible rubric for grounding, accuracy and review, with specific feedback. Team plan managers see skill progress and a team report, never raw chat logs. Try it with the 7-day free trial; no credit card is needed.
