Microsoft Publisher begins disappearing from PCs after 35 years, and your .pub files won’t open in Microsoft 365 anymore

AI-summarised brief · reviewed before publication

Microsoft Publisher, a 35‑year‑old Office application, has been retired and is no longer supported on Microsoft 365 subscriptions as of October 1, with perpetual versions losing support on October 13. Users who still have Publisher installed can back up their .pub files and convert them to PDF, either manually or via a PowerShell script. Microsoft recommends using Word or PowerPoint as functional substitutes for most Publisher tasks, though editing complex layouts remains challenging.

💡 Why It Matters

  • · The abrupt end of Publisher forces small offices and non‑profits to re‑evaluate their document workflows, potentially increasing reliance on Word and PowerPoint and prompting a shift toward PDF‑centric workflows.
