Office 365: How to force users to change their password /O365

First we will see how to do it for one account then we will see how to do it for multiple accounts.

1. Install Prerequisites:

      We will need MSOnline module to connect to Office 365 with PowerShell. 

       Open a PowerShell prompt with administrator rights :

2. Install MSOnline module :

    

         It will Also install NuGet Provider , accept and yes to continue.

 

3.Connect to Office 365

    Use Connect-MsolService to open the Microsoft Office 365 sign in window :

  

   Now a Pop Up windows will open For Microsoft Oath2 Security , Name and password of Administrative user or Global admin must be given here for making any changes. 

  

4.Reset user password :

         4A.Force new password : 

                      With this command we can set a password for a user :

                              ForceChangePassword : Indicates whether the user must change the password the next time they sign in....

     4B.Force user to change password at next logon

                  After this command, the update password procedure will happen next time user will connect                 (it will be slower to apply with Outlook clients because it uses a cache mechanism) :

                    -ForceChangePassword: Indicates whether the user must change the password the next time they sign in

                    ForceChangePasswordOnly: prevents the command Set-MsolUserPassword from generating a random password (source)
