If user has no admin privileges, we will get the error same as you.

Get-AzureADDomain : Error occurred while executing GetDomains
Code: Authentication_Unauthorized
Message: User was not found
HttpStatusCode: Forbidden

The reason is that, the cmdlet GetAzureADDomian has no tenant specified, so the connection was established to a domian, where user has no admin privileges.

To ensure connection to expected AAD domian, the tenant ID must specified in call to Connect-AzureAD cmdlet.

PS C:\windows\system32> Connect-AzureAD -TenantId

As already answered here, please use:

PS C:\windows\system32> Connect-AzureAD -TenantId {YOUR_TENANT_ID}
Example:
PS C:\windows\system32> Connect-AzureAD -TenantId ce1af0ab-ae35-4f60-8f2d-944444444444

It's a common mistake to use TenantId we get when executing Connect-AzureAd, like following:

enter image description here

But use the TenantId from Azure Portal --> Azure Active Directory --> Properties --> Directory Id.

The Directory Id = TenantId.
