Connect-SPOService: Could Not Connect to SharePoint Online – Causes & Fixes
This error can occur when you are unaware of how to connect to SharePoint Online with PowerShell. Then you make several mistakes, due to which the error persists. Let’s explore them along with the solutions in detail.
1. Legacy Authentication
According to the default settings, Connect-SPOService uses legacy authentication. It might occur if you add an AD FS claim rule to block the legacy authentication requests originating from the expected IP range.
Solution:-
Use the modern authentication parameter while connecting to SharePoint Online.
$creds = Get-Credential Connect-SPOService -Credential $creds -Url https://tenant-admin.sharepoint.com -ModernAuth $true -AuthenticationUrl?https://login.microsoftonline.com/organizations
2. Incorrect Admin URL
One of the major reasons behind the error is an incomplete or incorrect SharePoint admin URL. It should be in the format below
https://<tenant-name>-admin.sharepoint.com
Solution:-
Because of the incorrect or incomplete admin URL, you might encounter this error. So, check your admin URL by logging into the SharePoint Online Admin Center. Also, double-check the typos or missing components, such as -admin, to avoid the error.
3. Outdated Modules or Missing Installation
The Outdated SharePoint Online management shell can also be the culprit of the Connect-SPOService: Could not connect to SharePoint Online error. Ensure you are using the latest version of the management shell.
Solution:-
Execute the following commands to update SharePoint Online management shell using PowerShell.
Update-Module -Name Microsoft.Online.SharePoint.PowerShell
4. PowerShell Version Compatibility
SharePoint Online is also not compatible with the latest version of PowerShell. This issue might persist because of the PowerShell version above 7.
Solution:-
Check your PowerShell version with the below command, or downgrade it to 5.1 for an error-free workflow.
$PSVersionTable.PSVersion
5. Credential Authentication Failures
In SharePoint Online, there are issues while connecting to the SharePoint Online admin account when MFA is enabled.
Solution:-
Instead of using the Connect-SPOService, use the Connect-PnPOnline. But firstly, install it using the command below.
Install-Module -Name PnP.PowerShell
6. Trying to Connect Non-Admin Account
The Connect-SPOService can only allow you to connect to the Microsoft SharePoint Online Admin Center.
Solution:-
Check the account that you want to connect to the PowerShell and make it an Admin account if not. It will resolve the Connect-SPOService: Could not connect to SharePoint Online error.
7. Proxy Issues
There might be a chance of proxy issues while connecting to SharePoint Online.
Solution:-
Add the below command above the Connect-SPOService command.
$Details = [System.Net.CredentialCache]::DefaultCredentials [System.Net.WebRequest]::DefaultWebProxy.Credentials = $Details
8. Incorrect Protocol
If you are using HTTP instead of HTTPS, then it causes the error.
Solution:-
Correct the protocol from HTTP to HTTPS (HyperText Transfer Protocol Secure).
If you are facing this error while planning to merge two SharePoint sites. Then you can use the Efficient SharePoint to SharePoint Migration Tool. While using this tool, you do not need to execute the PowerShell commands.
It is a standalone tool to handle the migration even if the SharePoint files are larger.
