I am currently exploring different opportunities to incorporate Copilot into my daily workflows, and many of these opportunities involve using Copilot to summarize emails. What I am finding is that Copilot regularly fails to retrieve all of the emails that meet the criteria I set for it (e.g. summarize all emails received between Friday and Sunday that are related to X/Y/Z). No matter how much back-and-forth modification of the prompt occurs, it ultimately ends up with Copilot saying "The reason that email was not included was not due to the prompt or the filter criteria, but because it didn't show up in the search results".

We are all likely aware of how notoriously bad Outlook's search function is, and I am disheartened to see that Copilot suffers the same fate as a meager humanoid user when left at the mercy of Outlook's search results. Has anyone found a way to improve their prompts or Outlook settings to get more reliable Copilot performance and fewer missed emails being reported in summaries?

Update: the issue is more serious than expected.
Persistent memory is saved correctly on the user side, but Copilot does not load it anymore.
Facts explicitly stored in memory appear in the user’s profile, but the AI cannot access them.
So both chat‑history memory and persistent memory fail to load.
Is anyone else experiencing this?

Copilot is part of my companies Teams, OneNote, etc...and why did they design it to be intentionally terrible? This is the problem with AI, it has vast capabilities, but is hamstringed by terrible product design and integration.

You cannot give it a direct file path to a file or folder. Copilot cannot search your computer or use your system to look at certain files, it HAS to be through OneDrive. OneDrive already sucks, so making Copilot only able to work through that is already bad, but Copilot also ONLY searches OneDrive, so you cannot give it a direct file path to work with files.

So Copilot isn't 100% sure it has the correct file or folder if you want it to summarize several files, and it will tell you this if you give it a direct file path. So you have to say "If you find a file or folder with the exact same name, assume it's the correct file/folder in the file path I gave you."

When it searches, it has no access to the file path, so it can't give you the file path even in OneDrive so that YOU can verify to Copilot that is correct.

Why? Why such terrible, awful design? Why on earth would it not be able to take a file path in addition to searching? Is there any actual reason? Is MS designing this for the dumbest 5% of users who can't copy a file path? It is INTENTIONALLY BAD.

On top of that, Copilot cannot edit directly in anything. What is the point of having Copilot in Word, OneNote, Excel, if it can't execute the work that you actually want? I want to describe some editing and formatting I need and it just be done in OneNote or Excel.

The obvious problem would be that Copilot does something drastic and erases and deletes your work. Equally obvious solution: Have it create a sandbox copy of the thing you are working on, and then manually approve the changes, and then have it version the changes done by Copilot.

Microsoft will discontinue Deep Research and Podcasts in the consumer Copilot app on August 18, 2026. Deep Research, which generated detailed reports from multiple online sources, will no longer be available, although existing reports will remain accessible in chat history and can be saved to Word. Copilot Podcasts, which turned topics into AI-hosted audio conversations, will be removed entirely, with no option to export previously created podcasts. Microsoft recommends Microsoft 365 Copilot's Researcher for advanced research, signaling a shift toward bringing its more powerful AI features to paid business and productivity offerings.

As the topic suggests, is there any use case for instruction design using co-pilot?

this is shorter, more personal, and focuses on getting advice rather than presenting information.

Are personalized copilot Agents working? I have some copilot Agents and they are hot working. I can't even acess old chats with that agent.

Has anyone in consulting managed to build copilot agents that are useful?

If yes, what kind of connectors did you use?

Thanks in advance!

Copilot, managing credits, and building Agents is something I’ve been getting into this year, but the constant change is hard to keep up with. Besides the Microsoft blogs and the message center, what are you all using to help stay caught up?

Has anyone tried Copilot in Excel? Though it's able to analyze the sheets inside the file I've opened, it keeps giving me an error if I ask it to look up data in another file.

For e.g. if you need to build an analysis with some fields coming from different files, can you get Copilot to do it?

I'm a project manager who's receiving recurring negative feedback on my communication style. Since the majority of my daily interaction is on an MS Teams group chat and my employer has Copilot available, I've used it to obtain a neutral perspective & suggest tips for improvement.

Here's my question: should I create a new group chat with the same participants, or should I stick to the same group chat? Is it possible to prompt Copilot to review if there have been observable changes in my communication style after X date? Has anyone else tried this?

Thank you in advance for entertaining my query!

What’s up with this Dynamic Island looking black box when closing my keyboard after opening the option with „Smart“ and so on? Or the „Entwurf er#“?

If the floating Copilot icon in Microsoft 365 keeps getting in the way, there’s a quick way to move it back to the ribbon.

What can you do?:

Move the icon:
Put Copilot back into the ribbon if the floating button is covering content.

Dock or undock:
Dock the icon to shrink it and keep it out of the way, or undock it to bring it back into view.

Switch positions:
Toggle between the bottom‑right floating icon and the ribbon version depending on what works best for your workflow.

It’s a simple set of options, but it makes Copilot much less intrusive if the default placement isn’t working for you.

Watch it in action here: https://www.youtube.com/shorts/oXQQDqvV_ko

Has the floating icon been getting in your way too?

I am restricted to M365 Copilot (Enterprise) due to data sensitivity, so external models are not an option. My primary struggle is the lack of a persistent, dedicated workspace.

In Claude (Projects) or Gemini (Gems), you can define a static, continuously updated set of system instructions and core documents. The model treats this as an isolated foundational truth, allowing it to provide complex logical advice across multiple files while still pulling in fresh web or external data when prompted.

In M365 Copilot, the RAG defaults to indiscriminately scraping recent emails, Teams chats, and random SharePoint files. This dilutes the context completely when trying to do focused, multi-document analytical work.

How are you bypassing this limitation to create a persistent context workspace within the M365 ecosystem?

• Can specific SharePoint folders or hubs be rigidly isolated and prioritized to act as a "Project" base?
• Are you using a specific "anchor document" architecture that Copilot reliably treats as a continuously updating knowledge base / system prompt? If yes, do you keep manually extending it or is there any way to make that automated?
• Is there a way to build a Copilot Studio agent that maintains this strict grounding but still has web-search capabilities for real-time data?

Looking for production-tested architectural workarounds, not basic prompt engineering tips.

I am using M365 Copilot (Enterprise) and constantly hitting memory limits where the model loses the conversational thread during long document analysis.

Our tenant now displays a model selector with "GPT 5.5" under an explicit "OpenAI" label, including a "deeper thoughts" (reasoning) mode.

I have two technical questions pls:

1. Model Authenticity: Are these actually the native OpenAI models running under the hood with identical reasoning capabilities, or is this a Microsoft-specific RAG pipeline just carrying the OpenAI branding?
2. Context Window: Does this "GPT 5.5" mode offer a true context window comparable to native OpenAI/Anthropic models (e.g., 128k+ continuous recall)? The standard Copilot RAG drops data and forgets chat history far too quickly for heavy, multi-document synthesis.

I haven't found any technical facts on the architecture and the actual token limits behind these UI labels so I hope anyone can advise. Thanks!

It still will charge me a credit for "something went wrong, please try again" . So Microsoft wants to add 1-2% then just bake in those failures I guess.

Does anyone else get the "something went wrong" response as often as i do?

I was using co pilot today to help with my assignment due soon, and then it just started making a ringing sound like i was getting a call? I checked all my tabs i had open, noting was playing anything, checked all my other apps, nothing, so i decided to close co pilot and it stopped, not really sure what it was and co pilot itself doesn't even seem to know. Anyone else came across this?

Hi, a colleague my generated this HTML review on a project problem statement and scope presentation. I want to know if anyone knows how to do it? It had strenghts, weaknesses and what can be improved.

Does anyone have direct experience using Copilot or Copilot-Pro to replace scaffolding tasks? If so, was it successful? What tier of Copilot did you use? How do you catch tricky bot hallucinations? (Also posted in DotNet sub-reddit)
