Will Tech Soup's Publisher LS-54899 work after the Microsoft 365 version of Publisher goes away. Tech Soup's website says it is Publisher LTSC 2021, but other places say it is not perpetual like LTSC 2021 versions typically are.

Dear @Cindy Walker,

Based on the information currently available, TechSoup product LS-54899 appears to be a volume-licensed Publisher offer rather than the Microsoft 365 subscription version. It is said that, although Publisher will be removed from Microsoft 365 after October 2026, the perpetual version of Publisher can still be installed and used beyond that date. However, support for that version will also end in October 2026. Microsoft Publisher will no longer be supported after October 2026 | Microsoft Support

In practical terms, if LS-54899 is indeed the LTSC/perpetual version, it should continue to work after the Microsoft 365 version of Publisher is retired, but it would no longer be supported thereafter.

I hope the information shared helps point you in the right direction.

    TechSoup’s “Publisher LS-54899” is described as Publisher LTSC 2021. Office LTSC 2021 is a perpetual, one-time purchase product, not a Microsoft 365 subscription.

    Key points from the available information:

    1. Office LTSC 2021 (which includes Publisher on Windows) is a perpetual license:
      • It is a “one-time, ‘perpetual’ purchase” for commercial/government customers.
      • Office LTSC Professional Plus 2021 includes Publisher.
    2. End of support vs. loss of access:
      • Support for the perpetual version of Publisher ends on October 1, 2026, when Office LTSC 2021 reaches end of support.
      • After that date, Microsoft 365 subscribers lose access to the Publisher app in Microsoft 365.
      • Perpetual (LTSC/Office 2021) installations are not removed; they can continue to run after support ends, but they no longer receive updates.
    3. Effect on TechSoup’s Publisher LTSC 2021 (LS-54899):
      • As a Publisher LTSC 2021 perpetual license, it continues to work after the Microsoft 365 version of Publisher is retired.
      • It will not receive security or feature updates after October 1, 2026, but the installed application remains usable on supported operating systems.

    So, when the Microsoft 365 version of Publisher “goes away,” a properly licensed TechSoup Publisher LTSC 2021 (LS-54899) installation continues to open and edit Publisher files; it is not tied to the Microsoft 365 subscription lifecycle.
