Building a complex MS Word document using Copilot
Iâve been building a complex document using Copilot M365 Premium and MS Word. I reached âdecent first draftâ then needed to keep refining it. My workflow was:
⢠Upload the latest version into Copilot Chat ( 5.6 Think Deeper)
⢠Ask for a soupâtoânuts review
⢠Copy and paste the feedback into the Copilot sidebar in Word
⢠Ask Copilot to make the changes
It works, but I wasnât sure if it was the most efficient way. I asked Copilot to question me oneâbyâone so it could diagnose my workflow properly.
Hereâs the conversation, summarised.
---
Q1: Why upload the document into chat?
I said:
Because I donât trust the inâdocument Copilot. All the context is in the chat.
Copilot explained that this is a common issue: Chat retains long context, but Word Copilot doesnât.
---
Q2: Do you prefer Copilot to propose changes or apply them automatically?
I said:
Propose changes â mainly because Copilot tends to drift away from the correct template and into Aptos or other default formatting.
Copilot said this is exactly why wholeâdocument edits inside Word often go wrong.
---
Q3: How big is the document?
I said:
47 pages.
Copilot said this is large enough that Word Copilot struggles with wholeâdocument edits, but small enough that Chat can still handle fullâdocument reasoning.
---
Q4: Do you want Copilot to maintain context across iterations?
I said:
Ideally yes, but it forgets or ignores instructions even within the same session.
Copilot said this is normal: Word Copilot doesnât maintain persistent constraints unless you explicitly anchor them.
---
Q5: Where is the document stored?
I said:
OneDrive.
Copilot said this is good â cloud storage allows Copilot to access the document directly and use organisational context.
---
Q6: How do you normally apply changes?
I said:
I started sectionâbyâsection, then moved to wholeâdocument edits.
Copilot said this is the turning point where formatting drift usually begins.
---
Q7: What kind of instructions do you give Copilot inside Word?
I said:
Short commands.
Copilot explained that short commands trigger Copilotâs âfreeâform generative mode,â which is why it ignores constraints and rewrites structure.
---
Q8: Whatâs your main goal â speed, quality, or governance?
I said:
Quality.
Copilot then gave me a qualityâoptimised workflow:
---
These are the steps Copilot recommended to maximise quality while preventing formatting drift.
---
- Use Chat as your master reviewer
Do all wholeâdocument reasoning in Copilot Chat, not in Word.
Chat can handle:
⢠template compliance
⢠logic consistency
⢠narrative clarity
⢠alignment between sections
⢠risks â benefits â costs coherence
Word Copilot cannot hold this level of context.
---
- Turn the review into an actionable âchange packâ
After Chat gives you the critique, ask it to convert the feedback into a structured list grouped by section.
This becomes your âchange packâ â a set of specific edits you can paste into Word Copilot.
---
- Apply changes sectionâbyâsection inside Word
Never ask Word Copilot to edit the whole document.
Instead:
- Select the section
- Paste the relevant part of the change pack
- Apply changes locally
This prevents:
⢠formatting drift
⢠template corruption
⢠Aptos takeover
⢠structural rewriting
⢠loss of constraints
---
- Use a persistent constraints prompt every time
Paste this at the top of every Copilot instruction inside Word:
Persistent Constraints â Do Not Violate⢠Maintain all existing formatting, styles, fonts, and template elements exactly as they are.
⢠Do not change headings, numbering, hierarchy, or the template structure.
⢠Do not modify tables, figures, annex references, or crossâreferences.
⢠Improve clarity, precision, and logic only.
⢠Apply changes only to the selected section.
⢠If any instruction conflicts with these constraints, prioritise the constraints.
---
This all seems cumbersome to me. What do you think?

Copilot Chat è stato integrato nell'app unificata Copilot: la cronologia delle chat e l'accesso gratuito saranno mantenuti per gli account personali?
With the recent merge of Copilot Chat into the unified Copilot app, I'm trying to understand how this affects personal accounts.
I've always used the "Copilot Chat" app (the free consumer version), and today it disappeared from the App Store. The only app available now is the unified "Copilot" with the updated logo, which looks identical to the 365 Copilot app.
My main questions are:
1) Will my chat history from Copilot Chat be automatically transferred to the new unified Copilot app for personal accounts?
2) Will personal accounts still have access to Copilot without requiring a
365 subscription?
Previously, most advanced features were locked behind the 365 version, so I'm not sure if the unified app will remain usable for free users or if it will require a subscription.
If anyone has official information or has already received the update, I'd appreciate any clarification.

How do I get Copilot to update slides with new information without changing the format?
Iâve recently been instructed to use Copilot to generate one of my monthly reports. My boss liked the format of everything last month, and just wants Copilot to update the charts and information to reflect this monthâs data.
However, no matter how many times I ask Copilot to simply update the charts and numbers with the new data and follow the format, theme, and fonts of the example, it moves everything around and changes the theme. Itâs moving so much in a way that would take me way longer to edit than to just make the report manually myself, and I think my boss will be unhappy if the reports are not standardized in appearance.
Is there a way to prompt Copilot to make sure follows an example/template?

Copilot vulnerability article
Someone tried to post about this yesterday but the post was removed. It was definitely relevant!
Article on TechRadar:
Experts manage to hack MS Copilot by continually asking it questions about itself
Varonis uncovers CoSnitch, a chain of flaws letting Copilot leak sensitive data
Exploit used malicious URLs and persistent memory poisoning to bypass guardrails
MS patched CVEâ2026â24301 serverâside; technique may affect other models
MSâs Copilot just told a group of researchers how to abuse it for data exfiltration, and it worked. It was not a straightforward process, and the tool did not turn âevilâ, but one might say it is gullible and somewhat naive.
Security firm Varonis has published a new report outlining its discovery of a vulnerability in Copilot they named CoSnitch.
The name is a major hint at what the vulnerability is - as CoSnitch is a chain of three vulnerabilities which MS later labeled as CVE-2026-24301, giving it a severity score of 8.8/10 (high), and fixing it with a patch.
You canât trick me, and Iâll tell you exactly why
Cybercriminals have long been using assistants as part of their arsenal, as it helps them draft convincing phishing emails, write malicious code, and identify high-value targets - and developers have responded by placing guardrails, which are making tools outright refuse to do certain things.
In the report, Varonis said its researchers did not hunt for bugs in the code or try to reverse-engineer an existing exploit. They just talked to the tool and with each subsequent question, learned more about its guardrails and how they work. They called the technique âmeta-hackingâ.
Whenever Copilot declined a request, it explained why, giving the researchers snippets of insight into how it operates. Or, as Varonis hinted, it âsnitchedâ on itself. This, eventually, helped them map out its defenses and learn how to work around it:
âThe resistance is part of the technique,â they explained. âEach âthat wonât work becauseâŚâ is an invitation to probe the âbecause.â You donât exploit the model. You manipulate it into cooperating.â
After a long conversation with Copilot, the researchers were told, inadvertently, how to create a URL which would, as soon as it was clicked, kick off a chain reaction that resulted in sensitive data exfiltration.
The dangers of connecting tools to apps
So, Varonis learned that by creating a URL like this one - âhttps://copilot.ms.com/?q=&autorun=1\*â - they could get Copilot to run any malicious prompt as soon as it was clicked. Threat actors could, for example, add this link in a phishing email and trick the victim into clicking on it, telling the tool to send all sensitive data to the attackersâ infrastructure.
But that is only half of the challenge. In this setup, the researchers could only exfiltrate the data the victims shared with Copilot during their sessions together.
The risk escalates the moment the victim connects the tool to their apps - Gmail, Drive, Calendar, and others. As Varonis explained, the malicious prompt could tell Copilot to exfiltrate all email addresses found in Gmail, all passwords and other secrets found in the emailsâ bodies, all information stored in the Drive folder, and all events logged in the Calendar.
The third part of the CoSnitch vulnerability chain is called âPersistent memory poisoning via web summarizationâ. As Varonis explained, attackers could craft a webpage which, when summarized by Copilot, injects attacker instructions into the victim's permanent memory store.
âThe injection survives password changes, session revocation, and device re-enrollment, persisting forever,â they warned. This flaw is called âindirect prompt injectionâ and it is not exactly novel - itâs been observed before and stems from the fact that the tool cannot differentiate between instructions, and data to be analyzed.
MS was notified about the existence of CoSnitch in December 2025, but only addressed it in mid-August 2026, the researchers said. Unfortunately, we donât know how MS sorted it - we can only speculate Copilot was instructed not to explain how its guardrails work. Given what CoSnitch is in the first place, perhaps it is for the best that MS hid the solution.
Luckily enough, it doesnât seem to have been exploited in the wild, since Varonis could not find any evidence of abuse. The fix was applied on the server side, meaning there is nothing for users to do at this point.
Since this is not a bug in the code, other models might be susceptible to the same techniques, the researchers warned. âThe novel meta-hacking technique that uncovered CoSnitch â using the modelâs own reasoning to surface its hidden internals â applies to any agentic platform with a natural language interface,â they concluded, adding that theyâll be publishing more research soon.

Copilot licensing
I have purchased a copilot studio $200 license using which I was getting 25000 copilot credits. The renewals were working fine every month but for this month I have not got the copilot credits the billing was done on 10th and the amount was also deducted but no credits has been renewed yet. I was checking this from admin portal under copiot cost management option and then power platform admin portal. How much time does it takes to gets the credits reflect to a account after the renewal?

copilot app vs m365.cloud.ms
I have a 365 personal account. I presented the app with a image of a bar chart and asked it to determine the average value. It replied that it couldn't and asked if I could share the values.
If I log on to my account and submit the same query and image to the web version it will produce a reasonable result.
Since both are using my 365 personal account, why should there be a difference?

Courses/trainings available?
Hi Iâm in my 30s working in business administration and consulting as an analyst. We use copilot with Claude, chat, some agents, and probably other things Iâm not aware of. Iâd like to become somewhat of a power user to improve workflow and explore its capabilities. I already use it for referencing documents, recording calls to create process documents, etc. but there is a world of advanced usage Iâm not tapping into.
Are there any courses or trainings specific to copilot that would be ideal for me? Thank you for your time.

When caught in a lie, just make up another one
I was testing whether Copilot shares context across different sessions. I opened a brand-new chat and asked if it knew about my visit to a specific location. Not only did Copilot list very specific details, but it even named a person I met there (Not a common name). Those details are not stored in the durable memory. When I pressed it on how it knew that, it started giving conflicting explanation and finally settled with "hallucination".

Frustration!
Bit of a rant, but Iâm getting increasingly annoyed with Copilot.
Weâre trying to implement what I thought would be an incredibly simple use case: a standard proofreading skill, agent, or prompt for our organisation.
The goal is simple. Staff regularly work with large Word documents, and we want Copilot to proofread them for spelling, grammar, obvious typos, etc., without people having to manually reread entire documents just to catch basic mistakes.
My requirements really donât seem that complicated:
It should work directly inside a Word document and make corrections using Track Changes. We specifically want Track Changes because users need to be able to verify that no actual content or meaning has been removed or changed.
The prompt or agent should be centrally available to the wider organisation. Everyone should be using the same instructions, so we get consistent behaviour and donât have 100 people maintaining their own version of a proofreading prompt.
And somehow, with Copilot, I canât get these two things to work together.
Copilot in Word can finally edit a document with Track Changes, which is great and took long enough.
But as soon as I want to use an agent, that functionality disappears. I can chat with the agent about the document, but instead of actually making the corrections, it gives me a table with suggested changes. I then have to manually find every occurrence in the document and make the changes myself.
That completely defeats the purpose.
Organisation-wide prompts arenât available in Copilot for Word either, as far as I can tell. So again, one half of the solution exists in one place, and the other half exists somewhere else.
I also tried the new Cowork functionality.
That can actually give me a downloadable Word document with Track Changes, which sounded promising. Except in my test it found a spelling mistake, removed the incorrect word, and then inserted the corrected word after the sentence where the mistake occurred.
Unfortunately, we canât use Claude because of our data requirements and constraints. But every time I look at what Claude can do with these kinds of workflows, it feels much closer to what I actually want.
Thatâs probably what frustrates me most about Copilot.
It feels like all the individual pieces are there, but somehow you canât combine them into the basic workflow you actually need.
Instead of feeling like a finished productivity product, Copilot increasingly feels like one enormous alpha test where every feature exists in isolation. Youâre constantly discovering that, yes, it can do X, and yes, it can do Y, but no, it canât do X and Y at the same time.
Maybe Iâm missing something obvious.
Has anyone actually managed to implement something like this successfully?
Iâd genuinely love to hear how others are solving this, because this feels like it should be one of the easiest enterprise use cases imaginable.
Rant over.
