Microsoft says it’s committed to improving Microsoft 365 by shutting Publisher down, and you have 2 months to save your files
AI-summarised brief · reviewed before publication
Microsoft announced that Microsoft Publisher will be discontinued on October 1, 2026, ending its availability to Microsoft 365 subscribers. In an email to customers, the company said usage data showed Publisher was rarely used, prompting a reallocation of resources toward higher‑traffic services such as Microsoft 365 Copilot, New Outlook, and AI‑driven Designer. Existing Publisher users have two months to convert their files to Word or PDF, after which the app will be inaccessible through the subscription. The retirement also applies to perpetual‑license versions, with Office 2021 LTSC support ending on October 13, 2026, leaving those copies potentially vulnerable. Microsoft framed the move as a commitment to improve the overall Microsoft 365 experience by focusing on tools its customers actually use.
