Validate Get-PWFolders Attempt

There is no check you could run that wouldn't run the risk of being invalid when you finally execute the Get-PWFolders command. Even if it was the command immediately before the Get-PWFolders there is a chance the user renamed or deleted at exactly that time.

Instead what you want to do is catch the error and do something when the error occurs.  In PowerShell you use a Try Catch block to do this.

Try {
    Get-PWFolders -ErrorAction Stop
} Catch {
    # handle the error here
    write-error "An error occurred!"
}

You want as few statements in the Try block as possible so you can be sure where the error occured. there a bunch of options you can do with the Try Catch block to handle different errors in different ways.

If you just want your script to not stop and don't care about handling errors you can use -ErrorAction Continue or -ErrorAction SilentlyContinue options. The first will still print the error message but won't halt the script. The 2nd won't even print the error. I'm not a fan of these but for quick and dirty they're available.

Thank you, Kevin! Apologies for the extremely late response (side-tracked a bit longer than expected).
