Problem: When trying to import PowerShell module for SharePoint Online with “Import-Module -Name Microsoft.Online.SharePoint.PowerShell”, got an error message:
PS C:\> Import-Module -Name Microsoft.Online.SharePoint.PowerShell
Import-Module : Could not load type ‘Microsoft.SharePoint.Administration.DesignPackageType’ from assembly ‘Microsoft.SharePoint.Client, Version=16.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c’.

Solution:
This is due to DLL Version mismatch. To resolve the issue, follow these steps:
- Uninstall SharePoint Online Management Shell and SharePoint Online Client SDK if installed.
- Delete SharePoint Online Client Assemblies from: C:\Windows\Microsoft.NET\assembly\GAC_MSIL, remove all Folders starting with name: Microsoft.SharePoint*
- Uninstall the module with “Uninstall-Module -Name Microsoft.Online.SharePoint.PowerShell” and reinstall the module “Install-Module -Name Microsoft.Online.SharePoint.PowerShell”
I couldn’t get my on-prem SharePoint 2016 server to connect to my SharePoint Online server because of the .dll mismatch issue. (From what I can tell you just can’t run the regular SharePoint Online Shell on an on-prem server with SharePoint installed.) I WAS able to get the new SharePoint Online PnP PowerShell to work though, thanks to your other post here: http://www.sharepointdiary.com/2021/02/how-to-install-pnp-powershell-module-for-sharepoint-online.html
Thanks so much for posting that! Now I can connect our SP on-prem to our SPO and sync data between them with PowerShell! Game changer!
I’m getting this same error with my on-prem server. No matter what I try, I can’t seem to run the SharePoint Online shell on my on-prem SharePoint server. I’m trying to run a script that will sync fields from our SharePoint Online instance over to our on-prem server (running SP2016). I thought I could accomplish this on the same machine with 1 script. Is this not possible? The only workaround I can think of is to have 1 machine that can run the SPO shell dump the values in a csv file that the on-prem server can pickup 15 minutes later in another script. That seems crazy though when I should be able to just run 1 PowerShell script to do the whole thing at once. Am I missing something? Any help is greatly appreciated!
Thank you Thank you Thank you!
I think you should specify unless you’re hosting SharePoint server on step 2 ;). This would break SharePoint.
Remove all Folders starting with name: Microsoft.SharePoint*
This doesn’t work for everyone. I’m having the same issue but I did not have SharePoint Online Management Shell (or SDK). Nor did I have the assemblies mentioned under …/GAC_MSIL). Tried uninstalling from both VSCode/7.1.5 and from PS ISE and reinstalling. Can’t even import it now. I had to install SPOME (used Gil’s link, since it’s current) just to be able to service a client request until I can spend the time to figure it out.
Awesome, thank you very much. Tried following other guides and nothing worked until I came across your article here and now it works.
Totally Works for me. Thanks!
Thank you it worked! The last Install-Module step failed for me but I just downloaded the installation package from https://www.microsoft.com/en-gb/download/confirmation.aspx?id=35588
