Convert a domain from Federated to Standard (Available ADFS Service)

Have you converted your domain to a federated domain before your Single Sign-On is ready?

This will make your users unable to login to Office 365.

If your ADFS Service is available, run Powershell with Windows Azure/Office 365 Cmdlets.

Connect to Office 365

$LiveCred = Get-Credential
Connect-MsolService -Credentials $LiveCred
Set-MsolADFSContext -Computer <Incert your ADFS Server name>
Convert-MSOLDomainToStandard -DomainName <Incert your federated domain name.com> -SkipUserConversion $true/$false -PasswordFile C:UsersPassword.txt

-SkipUserConverstion $true/$false
$true will skip converting all users at the same domain to Standard users.
$false will convert all users at the same domain to Standard users.

If you only need some users, you can use value $true and convert the users you need to access Office 365 one by one.

-PasswordFile C:UsersPassword.txt

All users converted back to Standard users will need a temporary password and a list will be generated to distribute to your users.
