File Uploads Not Passed to Custom Engine Agent in Microsoft 365 Copilot Chat
Hi all, I'm working with a custom agent built in Copilot Studio (full authoring experience — topics, knowledge sources, agent flows) published to both the Microsoft Teams channel and the Microsoft 365 channel. I've noticed a significant UX discrepancy when it comes to file and image attachments, and I want to confirm my understanding and check whether any workaround or roadmap item exists. What works: ✅ File/image uploads work as expected in the Copilot Studio test pane ✅ File/image uploads work in Teams chat when interacting with the agent What doesn't work: ❌ File/image uploads do not reach the agent when interacting via the Microsoft 365 Copilot app (both the desktop app and the web experience at microsoft365.com) The UX problem: The M365 Copilot app presents a "+" button in the chat input area with options including "Upload" and "Take screenshot." Users naturally assume these options work. The file even appears as an attachment in the sent message — but the agent never receives it. There's no warning, error, or indication to the user that the attachment was silently dropped. This creates a misleading experience, particularly for end users who have no visibility into the channel behavior differences. What I've found so far: I'm aware this is documented as a known issue for custom engine agents in the Microsoft 365 Copilot Extensibility Known Issues page: "File attachments — Users can't upload files in agent chats and the agent can't return files for download." I also found a related GitHub issue (OfficeDev/microsoft-365-agents-toolkit #15325) where a Microsoft team member confirmed this is a "Copilot platform shortage" — not an Agents Toolkit issue — with no published ETA. My questions for the community and any Microsoft product team members: Is there any currently supported workaround to enable file/image input for a Copilot Studio agent running in the M365 Copilot app (desktop or web)? For example, any manifest configuration, agent settings, or alternate approach? Is this limitation being actively worked on? Is there a roadmap item or Microsoft 365 feature ID that can be tracked for when file attachment support is extended to custom engine agents in the M365 Copilot chat experience? Is the UI behavior (showing upload options that don't work) being addressed separately? Even if full file processing isn't ready, a visible warning or disabled state in the UI would significantly reduce user confusion. Any insight from others who have hit this — or from Microsoft PMs — is appreciated. Happy to share more configuration details if helpful. Thanks! Brian
Cannot access admin.microsoft.com – need Global Admin role assignment
Buongiorno, ho acquistato una licenza Microsoft 365 Premium, ma il mio account non risulta amministratore del tenant. Non posso accedere al portale https://admin.microsoft.com/?utm_source=copilot.com (errore: “non hai accesso”) e non ho alcun altro account amministratore disponibile. Ho necessità di diventare Global Administrator del tenant per abilitare funzionalità avanzate come Copilot Studio. Il supporto Microsoft mi ha indirizzato qui per avviare la procedura di verifica e recupero del ruolo amministrativo del tenant (“tenant admin recovery”). Chiedo assistenza per: identificare il tenant associato alla mia licenza, verificare l’assenza di un amministratore globale, assegnare il ruolo Global Admin al mio account. Grazie per il supporto. Cordiali saluti,

Hi, I really enjoy using the new workflow designer. I've a triggered workflow (Email arrives) that I added into a solution. I'd like to use environment variables from within the workflow. The variables and the workflow are in the same solution. Unfortunatly the environment variables are not visible like they were in the old designer. How can I access them ? Thanks in advance
Copilot agent sending emails to incomplete tasks
Hi Folks, I am new to this forum but want to share an interesting thing which I did with my first copilot agent. I have built an agent which can read incomplete number of "time-reported hours" from timesheet report and send individual emails to all those with "missing hours" in the body of email. This acts as a reminder for all the folks who missed filling their timesheets. The agent has worked well so far.The Employee Self-Service agent - how to find it
I see that Microsoft has put a lot of efforts to marketing the Copilot Employee Self-Service Agent but it seems it is not available for every tenant. I have already checked on several small and mid ones (5-2k users) and cannot find it in templates. As I understand from what I already red and saw, this is a template that should be available to you when you start building agents. Unfortunately when I enter Copilot Studio and enter in the search ESS (abbreviation from Employee Self-Service) I got only those two agents marked red filtered (see screenshot below). When I installed IT Helpdesk agent, I do not see topics related to HRSD in ServiceNow which I need. I found the Employee-Self-Service-Agent-Developer-Kit that contains same examples of the ServiceNow HRSD topics, but when I copy the YAML code of those topics to my agent I got some references to topics that I do not exists in my agents. Anyone has struggled with the same? Or maybe you have access to the Employee Self-Service agent and can share the basic solution/topics with me?

Copilot studio Agents published on Sharepoint
Hi everyone, I'm hoping someone can confirm or correct my understanding of a limitation we're experiencing. We have a Copilot Studio agent published to a SharePoint site. When users interact with the agent, they are unable to see their previous chat history — unlike the built-in SharePoint AI agents (e.g. SharePoint Agents / Copilot for SharePoint), which do appear to retain and display conversation history. Is it correct that Copilot Studio agents published to SharePoint do NOT support persistent chat history visible to the end user, while native/built-in SharePoint AI agents do support this out of the box?
