Upload of Network Share to Sharepoint Document Library

This script will give you the highlevel attributes such as Created time and Modified time. Please modify the script with the required attributes. 

You need to create a csv file with columns Sitename (Site url) and UserFolder (Parent folder path). 

Downlaod the file 'uploadfiles.psm1' from the attachment and place it in a folder. Replace the Import-Module path with the path in which the psm1 file was placed and run the script. 

FYI: This script can also be used to copy files to multiple sites by mapping the site urls in the csv. 

#$cred= Get-Credential
$csv = Import-Csv 'C:\csv\users3.csv'
$User = "Admin@tenantname.com"
$Password = "password"


#Add references to SharePoint client assemblies and authenticate to Office 365 site – required for CSOM
Add-Type -Path ([System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client").location)
Add-Type -Path ([System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.runtime").location)
