Copilot Cowork launches iOS and Android apps for on-the-go use

Microsoft expanded Copilot Cowork on May 5 with mobile access on iOS and Android, reusable “Skills” for repeatable workflows, and a broader plugin system that connects the product to Microsoft and third-party business tools. The update was announced in a Microsoft 365 blog post by Charles Lamanna, the company’s executive vice president for Copilot, Agents and Platform. Microsoft says the features are part of its Frontier preview program rather than a general release. Microsoft’s documentation says Cowork is available through the Microsoft 365 Copilot mobile app on iOS and Android. ### Where does Cowork now run? Microsoft said Cowork now runs on iOS and Android in addition to the browser and Microsoft 365 Copilot desktop apps for Windows and Mac. The company said the mobile version lets users start a task on a phone and let it continue in the cloud while they move back to desktop later. (microsoft.com) Microsoft Learn documentation says Cowork is a preview feature in Frontier and may change over time. The same documentation says Cowork can send emails, schedule meetings, create Word, Excel, PowerPoint and PDF files, post in Teams and manage calendars, with user approval before actions are applied. ### What are “Skills,” and what can users do with them? (microsoft.com) Microsoft said a Skill is a reusable set of instructions that tells Cowork how to complete a task or workflow. Lamanna wrote that Microsoft is adding built-in Skills for common work such as creating documents, coordinating meetings and conducting research, and that users can also create custom Skills for recurring team processes. (learn.microsoft.com) Microsoft Learn says Cowork’s April 2026 updates added support for as many as 50 custom skills, which can be created through natural language or from files stored in OneDrive. The documentation also says OneDrive and SharePoint now support Markdown files for skill files. ### Which plugins and connectors did Microsoft show? Microsoft’s Frontier features page says Cowork now supports native, custom and partner plugins that package skills and knowledge into workflows deployed across an organization. (microsoft.com) A Microsoft Community Hub post explains that connectors act as the bridge to external platforms, while a plugin can package connectors, skills, or both together for a specific job. (learn.microsoft.com) The same Microsoft post says native integrations include Fabric IQ starting with Power BI and Dynamics 365 plugins for Sales, Customer Service and ERP. It also says partner integrations for LSEG, Miro, monday.com and S&P Global Energy are due “in the coming weeks,” with Adobe, Atlassian, Box, Enosix, Harvey.AI, Money Forward, Morningstar and Swoop by Prezi also on the way. (microsoft.com) ### What kinds of work is Microsoft using to pitch Cowork? Microsoft’s FAQ says Cowork is meant for “multi-step work across Microsoft 365” rather than the single-conversation drafting and summarizing associated with Copilot Chat. The company says users can ask it to prepare daily briefings, search across an organization, conduct research, draft stakeholder communications and schedule prompts to run automatically. (techcommunity.microsoft.com) Microsoft’s March 9 launch post and May 5 update describe examples including cleaning up a calendar, preparing for meetings, generating structured documents and coordinating inbox workflows. A Microsoft 365 YouTube video published March 9 said Cowork handles “long-running, multi-step work” inside Microsoft 365 and can keep tasks running for minutes or hours. (learn.microsoft.com) ### Who can get it now, and what happens next? Microsoft says Cowork remains part of the Frontier program, which the company describes as early access to experimental AI features across Microsoft 365 and Copilot. Microsoft Learn says preview features are subject to existing customer-agreement preview terms and can have restricted functionality. (microsoft.com) In the coming weeks, Microsoft says the next visible milestone is the arrival of partner plugins for LSEG, Miro, monday.com and S&P Global Energy. The company’s Frontier pages and release notes list mobile support, plugin management through the Microsoft 365 App Store and Agent 365 integration for observability, security and governance as the current state of the rollout.
