Can't change password in open xchange

Simply trying to change my password in Open Xchange for my email. I go in, go to Configuration, click on Password, I enter my current password where it says, Your old password. I then enter a new password, I confirm it, and then I click Save. It then logs me out. I then try the new password and it doesn't work while the old one still does. My entire staff is dealing with the same issue.

While I can go in as an admin and manage the accounts, my staff cannot and I want them to have their privacy. Any help?

Have tried many times and looked for solutions. I've also tried it using Chrome, Firefox, and IE. No good.
