Microsoft recently announced that the OneDrive for business client will support automatically mapping SharePoint sites – Which is something I’ve been working on to script for some time now. Automapping sites will be a great benefit for migrations where users are saying goodbye to the good old file system, and hello to SharePoint online. Combined with Files on Demands most users won’t even know the difference.

The only sad part about it is that my pretty cool logon script will become useless fairly soon, anyway I’m sharing this to everyone. Its still in a pretty unfinished state, but it might help you if you are currently struggling with this:

<#
.SYNOPSIS
Automaps the Onedrive client to sync with a sharepoint library
.DESCRIPTION
Run the script with all mandatory parameters
In order to use the parameters you need to fetch them from the applicable site.
Every _api link should have tenantname.sharepoint.com/ in front of it if it's the default site, or tenantname.sharepoint.com/sites/SITENAME for any other site.
If the _api data is hard to read, use a tool like https://codebeautify.org/xmlviewer
.PARAMETER siteid
_api/web
Search for "D:Id", here you will find the SiteID Guid
.PARAMETER webid
.PARAMETER listid
_api/web/Lists/getbytitle('NAMEOFTHELIBRARY')
Search for "D:Id", here you will find the ListID Guid
.PARAMETER URL
_api/web
Search for "D:web", here you will find the SiteID Guid
.PARAMETER webtitle
Set this to the name of the organisation
.PARAMETER listtitle
Set this to the name of the library
.EXAMPLE
.\SharePoint_Automapping.ps1 -siteid GUID -webid = "GUID" -listid = "GUID" -URL https://company.sharepoint.com/ -webtitle Company -listtitle Documents
which will create the following link for the OneDrive app:
start "odopen://sync/?siteId=GUID&webId=GUID&listId=GUID&userEmail=$upn&webUrl=https://company.sharepoint.com/&webtitle=Company&listtitle=Documents" 
.NOTES
In order to retrieve the _api info you need to log in to the tenant, no admin rights are necessary.
