Windows 10 default app setting not working

I have a client with two new Windows 10 computers with Office 2016. Default mail app setting is not working on both computers. Outlook is set for the default mail app. When you click on an email address in Word, it brings up the box asking "how do you want to open this." I click Outlook and check the box to "always use this app."

Next time you click on an email address, the same box pops up.

I verified it is set in default app settings.

This is also causing an issue with Adobe. When you click to send, it can't find the default mail app.

i updated Windows 10 with the latest updates. In this version of Office 2016, there is not an option to Check for Updates in Word or Outlook.

Any idea how I can fix this?

The default app is set to Outlook. It still prompts every time you click an email address link and sending from adobe gets an error that it cannot send. I'm sure that is because the default app is not registering even though it is set to Outlook

I went to uninstall Office but it was not in Programs and Features. I also realized that the mail app was not in control panel. I uninstalled Office through Windows 10 apps and features. I could not  reinstall it by downloading from the account.  I got an error "couldn't stream office." I downloaded the offline installation and installed that. That fixed the problem and everything is working now.
