If Publisher is no longer available in Microsoft 365
Microsoft scheduled Publisher removal from Microsoft 365 for on or shortly after 1 October 2026 as its update rolls out. Support for perpetual Publisher 2021 ended on 13 October 2026. Perpetual versions can still be installed and used without support.
Open your Publisher postcard in Megal Publisher and carry on with the next edition. Update the text, pictures and layout, then save an editable .mpub master to return to later. Keep the original .pub file with your project records.
Separate content, structure and proofing decisions so a late correction does not undo earlier work.
Start with your Publisher file
Choose the .pub file for your postcard and open it in Megal Publisher. Keep the original as a backup and give the new edition a clear name. Have your updated front visual and headline, short supporting message, recipient or address area, sender identity and response details and any conditions ready so you can move straight into the changes that matter to your readers.
Work with editable text, pictures and layouts
Megal Publisher reads your .pub file directly and brings its page objects into the editor. Select text to update the wording, replace a picture, adjust a shape or arrange the layout for your next edition. You can work in your browser without installing Microsoft Publisher.
Make the next edition your own
Design front and reverse together, leaving the required mailing zones clear and keeping the response instruction easy to find. Refresh front visual and headline, short supporting message, recipient or address area, sender identity and response details and any conditions and use the formatting controls to keep headings, body text and practical details consistent. Add new pictures or use Megal AI to help with text and imagery. Review the updated content against your brief so every change supports the goal to deliver one memorable front message and a practical reverse-side response.
Save a reusable Megal master
Save an editable .mpub working file and reopen it whenever you need another update. Keep the original .pub file with your project records. When the edition is ready, use Print Preview, then create the required PDF or print proof with Professional. Confirm the postal operator’s current size and clear-zone requirements as well as the printer’s bleed and duplex settings. Archive the approved output with its editable master for the next edition.
Use before sign-off
A short working checklist
Publisher migration checklist
Keep the original .pub file and a reliable visual reference.
Confirm imported page size, orientation, count and order.
Compare fonts, overflow, columns and linked text on every page.
Check images, crops, transparency, shapes, borders and tables.
Save and reopen an editable .mpub working file.
Approve a new PDF or printed proof before distribution.
Keep the source and proof together. Megal Publisher can keep the page objects editable in an .mpub project. Preserve the source facts and the approved output as separate records so later changes can be checked.
Frequently asked questions
Questions about your Publisher file
What should I know about PUB compatibility?
Font availability and some advanced or older Publisher features can affect imported layouts. Missing fonts may change line breaks, and complex effects or page objects may need adjustment. Verify front/back order, postal guide elements, rotated address text and full-bleed picture placement from Publisher. Keep the original .pub file and compare important publications with an original PDF or printout before final output.
Can I save the publication and keep editing later?
Yes. Save an editable .mpub project and reopen it in Megal Publisher for the next update. Full editable Microsoft .pub export is not currently available.
