Hello @rajesh vsnk ,
In my testing, I can not insert the Document ID or Unique ID as a Footer into the uploaded documents through PowerShell script.
However, you can manually add the Document ID as a Footer to each word document.
Please the following steps:
1) Sign in the Document library as an admin
2) Open the word document in app
3) Go to the Insert tab, click on Footer menu, and then select Blank option
4) Select the [Type here], click on Quick Parts menu, and then select Document Property and select Document ID Value.
5) Close Header and Footer and save it.
6) When you open the word document again, you will find that the Footer has been set successfully.
Thanks,
Echo Du
