Powershell Sharepoint snapin when not on the sharepoint server - powershell

Question

I am new to both powershell and sharepoint, and I need to make script to automate the removal and uploading of attachments from outlook to sharepoint. I have easily completed the first part of extracting the attachment, however the uploading to sharepoint has become difficult do to my company's rules. As I understand to use sharepoint cmdlets you need to add the sharepoint snap-in but I am unable to do so because I dont have access to the sharepoint server. Is there anyway to the snapin without being on the server and if not can I upload it another way?

Answer 1

You can't add the SP snap in unless the server is a SP server. Instead, use a webservice/webclient approach to upload the file. Something like this should work depending on your SP version:

Answer 2

Accepted answer link is broken.
This script uses PowerShell to upload a file to a document library in SharePoint using purely web service calls so it could be done remotely, also meaning it should work with O365 though I have not tried.
These variables are used throughout the script for source file, destination file and authentication. If your workstation is on the same domain as SharePoint, and your logged on user has permissions to the SharePoint site, you can omit $username, $password, and $domain
$LocalPath = "C:\filename.docx"
$spDocLibPath = "http://site.contoso.com/sites/spteam/Shared Documents/"
$username = "someone"
$password = "somepassword"
$domain = "contoso"
$UploadFullPath = $spDocLibPath + $(split-path -leaf $LocalPath)
$WebClient = new-object System.Net.WebClient
if($username -eq "" -or $password -eq "" -or $password -eq "")
{
# Use Local Logged on User Credentials
$WebClient.Credentials = [System.Net.CredentialCache]::DefaultCredentials
}
else
{
# Alternate Login for specifying credentials
$WebClient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
}
$WebClient.UploadFile($UploadFullPath, "PUT", $LocalPath)
