Publisher 2021 can still be installed and used beyond October 2026 if it is the perpetual version, even though support ends. Microsoft 365 subscribers will lose access to Publisher after October 2026, but the perpetual version remains installable and usable after that date.
For preserving access to existing .pub files, the supported guidance is:
- Keep using Publisher with its current functionality until October 1, 2026.
- Before that date, convert important files to another format.
- For viewing, save Publisher files as PDF:
- Open the Publisher file
- Go to File > Save as
- Choose a location
- Select PDF as the file type
- Select Save
- For editing after conversion, open the PDF in Word:
- Open Word
- Go to File > Open
- Open the PDF file
- Select OK
Microsoft also states that many common Publisher scenarios are available in Word and PowerPoint, including greeting cards, business cards, calendars, and other similar projects.
The virtual machine suggestion shown in the screenshot is not covered by the available Microsoft documentation here, so the supported facts are limited to the retirement timeline, continued use of the perpetual version after support ends, and the recommendation to convert files before October 2026.
