Microsoft Publisher has been part of the Office suite since the 90’s, offering publishing capabilities.
It has not been loved and used.
After October 2026, Publisher will reach its end of life. After that time, it will no longer be included in Microsoft 365 and existing on-premises suites will no longer be supported.
Until then, support for Publisher will continue and users can expect the same experience as today.
In addition, don’t forget that is you are using Office LTSC 2021 will reach end of life at the same time.
