What’s new for SharePoint – October 2025
I can’t remember a month this quiet for SharePoint in recent memory. Still, don’t let the calm fool you—there are updates that will improve the way you work, whether you’re an end user or an administrator. My top highlight this month is the new Admin view, which gives administrators the ability to view and manage all SharePoint agents directly from the Admin Center.
The second standout is the updated document library experience. I have mixed feelings about this one. While I usually welcome UX improvements, the decision to swap the positions of the view selector and the New/Upload button feels counterintuitive, and I’m still trying to understand the logic behind it.
Beyond these, there are more than 10 new announcements waiting for you in the full post, from OneDrive enhancements for departing employees to Copilot integrations and advanced management insights. Dive in to explore what’s new and what’s next for SharePoint and related technologies.

OneDrive enhancements simplify file management for departing employees by improving notifications, filtering, and enabling bulk file transfers that preserve sharing. Access transfers automatically to managers with email alerts. Rollout begins mid-October 2025, requiring no admin action but recommending informing stakeholders and updating documentation.

Microsoft 365 admins can now manage SharePoint agents in Copilot Chat via a new Agents section in the Copilot Control System. They can view, block, or unblock agents starting late September 2025. This feature is enabled by default and only affects Copilot Chat.

We’re improving version history for SharePoint Lists and Document Libraries generated with grid view editing. This change improves reliability, reduces storage, and streamlines the user experience by consolidating multiple edits into one where possible. Automation rules and flows, if configured with item level edits, will also now trigger more efficiently.

We’re introducing column metadata support for queries in Microsoft 365 Copilot when a SharePoint library or folder is attached or its URL is provided. This enhancement improves contextual relevance by enabling Copilot to leverage additional metadata from the selected library, delivering more accurate and meaningful results.
OneDrive will introduce a floating Copilot button starting October 15, 2025, providing quick access to AI-powered file actions like summarizing and comparing documents. Enabled by default for eligible users, it streamlines navigation and offers contextual recommendations within the OneDrive web interface.
SharePoint Online Tenant Rename is now generally available without site count limits, enabling domain name changes for all tenants starting October 16, 2025. It supports business continuity, Microsoft 365 integrations, and requires SAM licenses for tenants with over 10,000 sites. Vanity domains and Multi-Geo are unsupported.
Microsoft 365 admin center will introduce Capacity Pack support for SharePoint Agents and Copilot Tuning in late October 2025, allowing prepaid message bundles to manage costs before pay-as-you-go charges. Admins can allocate packs, monitor usage in PPAC, and control environments via Entra ID. No prior action needed.

Customers can now connect Microsoft 365 Copilot to SharePoint Server with Copilot connectors to query and manage enterprise documents.
Microsoft is updating SharePoint document libraries with a simplified command bar, improved breadcrumb navigation, more visible custom views, filter pills, and a new options button. Changes begin November 2025, preserving existing customizations except for updated command bar formatter behavior. No action required to prepare.

The floating Copilot button is a quick-access button that appears prominently in your OneDrive web interface. It’s your gateway to Copilot-powered actions —right where you need them. Instant Copilot Access: Ask questions about your files, summarize documents, or compare content—all without leaving OneDrive. Contextual Recommendations: The button will suggest helpful actions based on your file selection—like generating a status report from a file you’ve selected or generating a summary of a new file shared with you. Streamlined Navigation: No more hunting through menus; the Copilot floating button brings the most relevant tools to your fingertips.
A new Copilot icon button provides a quick, visible entry point to Copilot directly within the file previewer in OneDrive. Positioned at the bottom-right corner (instead of the command bar), this button surfaces contextual prompts tailored to the file type and offers seamless access to Copilot chat, making it easier to get insights and take action without leaving the preview experience.

Rich insights on agents accessing content in SharePoint and OneDrive sites as part of SharePoint Advanced Management controls.
Agents in OneDrive, launching worldwide in November 2025, let Microsoft 365 Copilot users group files for AI-powered Q&A, summaries, and collaboration. Agents are saved as .agent files in OneDrive, editable and shareable with teams, enhancing project efficiency without admin action required.
