Recently I was building a new SharePoint 2016 farm and came across the below error with older PowerShell SharePoint 2013 install scripts. Expected error as Microsoft moved the functionality to Office Online Server. Cheers!
- The term ‘New-SPExcelServiceApplication’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
- Microsoft removed the Excel Service Application from SharePoint Server.
- Office Online Server has the functionality going forward.
