Confirmed facts: what has changed in October 2026?

Microsoft says Publisher removal from Microsoft 365 began on or shortly after 1 October 2026 through an update rollout. It is no longer included in the subscription, although removal timing can differ between computers.

Perpetual Publisher support ended on 13 October 2026. Microsoft confirms these versions can still be installed and used to open and edit files. That differs from subscription access, but continued operation does not mean continued support.

Microsoft Publisher retirement dates and licence differences

A perpetual licence is not a permanent security guarantee

Microsoft's Office 2021 guidance confirms that support ended on 13 October 2026, with no extension or extended security updates. Technical support, bug fixes and security fixes have ended even though applications may continue to function. Older Publisher releases may already have been unsupported before this October deadline.

Our practical advice is to treat any remaining licensed Publisher installation as a temporary migration resource, not a reason to keep using unsupported software for everyday work. Ask IT to check the exact product, licence and device before planning conversions. Do not disable Office updates or reinstall an old subscription build to try to avoid retirement.

Step 1: find the Publisher files that matter

Start in File Explorer with the relevant Documents or shared folder and search for *.pub. Repeat for other approved storage locations. In OneDrive and SharePoint, search for .pub and check the libraries where teams keep publications. Search results depend on permissions, indexing and the location searched, so one empty result is not proof that no files exist.

Our recommendation is to ask the people who produce documents, not just the people who manage computers. A school office may keep prospectuses and newsletters separately from classroom resources. A business may have brochures with marketing, price lists with sales and labels on a workshop computer.

  • Check approved network shares, Teams files, SharePoint libraries, OneDrive folders and authorised archive storage. Ask IT to help with former staff accounts or disconnected drives rather than bypassing access controls.
  • Record each important file's location, owner, purpose, last required date and next planned use. Include linked images and the original logos or photographs needed to rebuild it.
  • Mark each item as archive only, needs occasional editing or needs a replacement template. Prioritise upcoming events, current prospectuses and operational forms.
  • Confirm that originals are backed up and that a sample can be restored before changing anything. Keep approved permissions and retention rules in place.

Step 2: preserve finished documents as PDF

Where an authorised, working and licensed Publisher installation remains available, work on a copy. Open the publication, choose File, then Save As, select PDF and save it beside the original. Alternatively, use File, Export, Create PDF/XPS Document and choose PDF.

Microsoft provides export options for online distribution, ordinary printing and commercial printing. Choose the intended use rather than automatically selecting the smallest file. Ask your printer which settings they require for a booklet, brochure or professional print run.

Our practical check is to open the exported PDF independently and inspect every page. Compare text, images, fonts, page size, page order and any links against the original. For folded documents, test a printed copy before approving the result. Keep the .pub original and source assets even after the PDF passes inspection.

A PDF preserves the finished output. It is not a promise of easy future editing or an automatic guarantee of accessibility. Check reading order, meaningful text and accessibility requirements separately where documents will be published online or shared with parents and customers.

Microsoft instructions and PDF export quality options

What if Publisher has already disappeared?

Do not rename a .pub file to .pdf. Changing the extension does not convert the document. First look for an existing approved PDF, a previous print proof or another final export. Ask the document owner or print supplier whether they hold a usable copy.

If no export exists, ask your IT provider to check whether a legitimately licensed perpetual installation is available for controlled conversion. If not, agree an approved conversion service or rebuild the publication from its text and source assets. Do not download unofficial Publisher installers or assume that another application's import will preserve the design.

For large collections, Microsoft provides a sample export script that requires working, licensed Publisher. Our advice is to have IT review and test it on a small copied sample, check errors and validate the PDFs before processing the full archive. It is not a way to convert files without Publisher.

Step 3: decide which documents still need editing

Our recommendation is to avoid spending time recreating every old leaflet. A completed event programme may only need a checked PDF archive. A prospectus used each autumn needs an editable master, a named owner and a clear place to save future versions.

For a document that is mostly text, desktop Word can open a PDF and create an editable copy. Use File, Open, select the PDF and accept conversion. Microsoft warns that the layout may change, particularly with graphics, tables and complex page elements. A graphic heavy page may become an image with no editable text.

Treat that conversion as a starting point, not a finished template. Compare it with the PDF, correct the layout and save a new Word master without overwriting the archive. For heavily designed publications, rebuilding a clean template may be more dependable than repairing repeated conversion errors.

Step 4: choose a sensible replacement for the job

Microsoft suggests Word for newsletters, labels and letterheads, Word or PowerPoint for brochures, and PowerPoint for posters. These are replacement workflows, not a promise that either application directly opens .pub files.

Our practical recommendation is to start with a supported application your staff already know and are licensed to use. Test one real document before moving a whole department. Check page dimensions, duplex printing, brand fonts, accessibility and how colleagues will share the editable master.

  • For school letters, newsletters and text led information packs, consider a structured Word template with consistent headings and styles.
  • For simple posters, notices and certificates, consider a PowerPoint template with the correct page size and a checked PDF export.
  • For labels and envelopes, test Word against the actual stationery and printer rather than assuming the old Publisher layout will align.
  • For complex prospectuses, magazines or professional print work, assess a supported page layout application with your designer or print supplier. Check licensing, training, export requirements and compatibility before purchasing.
  • If considering an online design application, get organisational approval for its accounts, storage and data handling before adding confidential material.

Avoid unsafe online conversion shortcuts

Microsoft notes that conversion tools vary in quality and are not supported by Microsoft. Our security advice is to treat uploading a publication as sharing its contents with another organisation. A free conversion button is not evidence that the service is suitable for business or school information.

Do not upload pupil details, photographs, safeguarding material, staff information, customer lists or confidential pricing to an unapproved converter. Ask your IT or data protection lead to review the provider, retention and deletion arrangements, storage location, access controls and contractual terms first.

Test only with a non confidential sample after approval. Do not grant access to an entire OneDrive account, enter your Microsoft password into a converter or install an unknown browser extension just to recover a leaflet. Prefer a controlled local conversion when feasible and verify every result.

A practical plan for your school or business this week

Bury I.T. Support can help businesses and schools in Bury and the surrounding area review Office licences, locate important documents and plan a controlled migration. For schools, we can work with your office team and leadership so the next prospectus or newsletter does not depend on one ageing computer.

Talk to us about your Publisher files and Microsoft 365 setup. Call 0161 884 3303 or email info@buryitsupport.co.uk. We will start with how your organisation works and what you need to keep using.

  • Nominate someone to gather the important .pub files and identify their owners.
  • Confirm the originals and source assets are protected by a tested backup.
  • Export and inspect PDFs for documents that only need reading or printing.
  • Rebuild the next few documents that need editing and agree supported replacement templates.
  • Record unresolved conversions, owners and deadlines. Remove obsolete Publisher installations through IT once migration is complete.
