Publisher Still Opens. Now What?
Microsoft Publisher’s retirement has not produced one uniform cut-off. Microsoft says removal from Microsoft 365 starts on or shortly after 1 October 2026 as its update rolls out. Perpetual editions remain usable for opening and editing files, but their support ended on 13 October.
Continued access therefore does not establish that retirement was postponed, or that a supported editing route remains. For a document owner, the useful question is more specific: who can produce the next approved version without depending on an untested assumption?
A readable copy is only half the job
Microsoft recommends PDF for viewing and conversion through PDF to Word for editing. The Word result is text-oriented and can change graphics-heavy layouts. Its illustrative export script requires a working, licensed Publisher installation, adaptation and testing.
BlackTree’s proposed acceptance test starts with a real recurring document and its next business deadline. Ask the person responsible for that document to nominate the content that must survive, then agree what would make the replacement unacceptable. A clipped address, missing approval statement or altered page order should become a recorded exception, not disappear inside a general claim that conversion worked.
Keep the original and the trial output together. Review both the screen version and the output actually used by the recipient. Then make a small, authorised change in the proposed replacement, produce another copy and have the document owner check it. This second pass tests the future working process, rather than merely demonstrating that an old file can be displayed.
Close the dependency, not just the ticket
For each document, record the owner, next deadline, comparison evidence, unresolved differences and the decision to accept or reject the replacement. If a critical sample fails, retain that exception with a named decision-maker and a review date. Do not mark the wider migration complete because one uncomplicated sample passed.
This is an editorial acceptance method, not Microsoft’s procedure or a claim that BlackTree has tested readers’ files. Its value is a traceable handover: the next person should know what was checked, what remains open and who must act.
Updated 15 October 2026: support-deadline tense corrected and the document-owner acceptance method expanded. Original publication date retained.
