Outlook.com won’t let me change passwords

I create company email accounts for anyone who gets hired at the company I work for.  If they forget their password, I can usually go into outlook web app and reset it for them.  The last time I tried to do  this, the reset button was gone.  From my mailbox I usually go to Options-See All Options-Manage My Organization.  Then I pick a user from the list and click the reset password button at the top of the page.  All the other buttons are at the top of the page, but reset password is gone.  Can anyone help?  Thanks so much!
