    Switching subscription tiers will not allow you to use Publisher because Publisher will be retired and removed from all Microsoft 365 subscriptions on October 1, 2026.

    Your standard Microsoft Word files (.docx) are separate from Microsoft Publisher. They will remain fully accessible, editable, and functional in Microsoft 365 after October 1, 2026, regardless of your subscription tier.

    Publisher files (.pub) are different. After the retirement date, you will no longer be able to open or edit .pub files using Microsoft 365 applications. Therefore, if you have existing Publisher files that you may need in the future, it is important to convert them before October 1, 2026.

    If you want to be able to access .pub files content, export or save them in alternative formats, such as PDF or Microsoft Word documents, before the retirement date. You should also consider transitioning your existing layout and design projects to applications such as Microsoft Word, PowerPoint, or third-party desktop publishing and layout tools.

    No. Switching to Microsoft 365 Business Premium does not preserve Microsoft Publisher after October 1, 2026 for Microsoft 365 subscribers.

    After that date:

    • Microsoft Publisher will no longer be included in Microsoft 365.
    • Microsoft 365 subscribers will no longer be able to open or edit Publisher files in Publisher.
    • Word files are not affected by Publisher retirement.

    If the goal is to keep working with Word documents after October 1, 2026, Microsoft 365 Business Premium includes the Microsoft 365 apps, so Word remains part of the suite. The retirement only affects Publisher.

    If there are existing Publisher files that still need to be viewed or edited after that date, the recommended preparation is to convert them before October 1, 2026:

    1. For viewing, save Publisher files as PDF.
    2. For editing, convert the Publisher file to PDF, then open the PDF in Word.
    3. Be aware that Word conversion is optimized for text editing, so layout can change, especially in files with many graphics.

    If a large number of .pub files exist, a file search for .pub on the PC, OneDrive, or SharePoint can help locate them, and bulk conversion can be automated with a PowerShell script.
