Error: "Cannot contact web site 'XXXX-admin.sharepoint.com' or the web site does not support SharePoint Online credentials".
You will likely see this error if you have disabled the ability for non-modern (legacy) authentication protocols within your SharePoint Online tenant.
To migrate to a SharePoint Online Tenant, you first must enable legacy authentication protocols. To do this, run the below commands against your SharePoint Online tenant:
Connect-SPOService -URL https://XXXX-admin.sharepoint.com
Set-SPOTenant -LegacyAuthProtocolsEnabled $TrueNote: You will need to update the URL to include the correct tenant name. This can be found by performing the following steps within your Office 365 tenant:
- Log in to the Office 365 Admin Center.
- On the left side of the portal, expand Admin Centers.
- Click SharePoint.
- Take the URL from the address bar.
Alternatively, you can go into the SharePoint Online admin center and under Access control choose Apps that don’t use modern authentication then click Allow.
Note: Changes may take up to 24 hours to take affect.

Using $UserCredential = Get-Credential throws the legacy login window. By using this, you are prevented from using the modern login. As such, the script above fails. The script above works if you eliminate the credentials piece:
Connect-SPOService -URL https://XXXX-admin.sharepoint.com
Set-SPOTenant -LegacyAuthProtocolsEnabled $True
After you do the Set-SPOTenant -LegacyAuthProtocolsEnabled $True, you might get the following error:
Your migration failed checking source credentials. The Application ID (AppID) for which the service ticket is requested does not exist on the system.
This means your admin account needs to an OnMicrosoft account. That is, user@xyz.onmicrosoft.com.
