What you’re seeing
- An error stating that a term "is not recognized as the name of a cmdlet, function, script file, or operable program".
- A command that works on one computer fails on another, or for one user but not another.
- The failing command belongs to a specific product, such as Exchange, Active Directory or Microsoft 365.
- Running a script by its file name fails, even though the file sits in the current folder.
- The error appears after moving a script to a new server or upgrading PowerShell.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The module that provides the command is not installed on this machine, or is installed in a location PowerShell does not search.
- The command comes from a management tool, such as RSAT or a vendor console, that was never installed here.
- The module only works in a different edition of PowerShell than the one being used.
- PowerShell does not run scripts from the current folder by name unless the path is written explicitly, as a safety feature.
- A typo, a renamed command in a newer module version, or an alias that exists only in someone's personal profile.
Why it matters
This is one of the most common PowerShell errors, and on its own it is harmless. In practice it shows up during migrations, new server builds and staff changes, exactly when scripts and procedures move between machines. Each failure delays the task at hand and can leave a multi-step process half done. It also exposes undocumented dependencies, such as modules only one admin had installed, which become a real risk when that person leaves.

Frequently asked questions
Why does it work on my colleague's machine?
Their computer most likely has a module, tool or profile setting that yours does not. We confirm what is missing before installing anything.
Is anything broken on the server?
Usually not. This error means PowerShell cannot find the command, not that the system is damaged.
