Brings to mind a line from an old folk song about worker's interaction with a machine he operates...
It should'a been melted 'bout twenty years back
but it feeds the boss and he loves that snack...
The boss being Gates, of course.
An email from the purveyor of my Microsoft 365 subscription, is informing me that, according to their control of my online subscription, I have to migrate all my files into another MS-365 computer program application like Word or PowerPoint. On a separate machine, from the year 2011, I have an installation of Publisher on a platform titled "Microsoft Office Professional 2010". Is the company going to be able to reach out to that computer and disable Publisher on it?
Short answer: No — Microsoft cannot reach into your 2010 computer and disable Publisher on it.
The uploaded email says that beginning 10/1/2026, Microsoft Publisher will no longer be supported as part of Microsoft 365, and it warns that after that date you will no longer be able to open or edit Publisher files with Microsoft Publisher. This wording is misleading and appears to refer to the Microsoft 365 version of Publisher, not to older perpetual-license copies such as Publisher 2010.

The key distinction is between two separate products:
Because your 2011 machine is running Publisher 2010 as part of Office Professional 2010, Microsoft is not in a position to remotely disable that installation merely because Publisher is being retired from Microsoft 365.
In practical terms, your Publisher 2010 installation should continue to run, continue to open and edit .PUB files, and remain usable so long as the software and computer itself still function.
The real limitations are different:
So the sensible conclusion is this: the email affects Microsoft 365 Publisher, not your standalone Publisher 2010 installation.
One prudent precaution is to export important Publisher files to PDF while you still have a working Publisher environment, so you preserve a durable readable copy of them.
