This worked! All we had to do was a quick repair of office and it started showing up again! thanks!

Repair Office installation
If the affected program was installed after Office, try repairing the Office installation.
- Open Control panel, Program and Features
- Find and select your Office or Outlook installation
- Click Change
- Select Quick Repair then click the Repair button. (In older versions of Office, the option is called Repair.)

Try this once again if you are not able to resolve then you may try their https://officeerror.com/ blog this is not Microsoft Website but they listed resolvable steps.

The Quick Repair does work, but I'm deploying Feature Build upgrades to our company and randomly the Default App for Outlook is not available until a QR is performed. My question to Microsoft is what is causing this random problem?Vishal Kumar

I have a bit of problem with the language, therefore be patient. I was worrying for 3 days about that problem as I am not very good at computers, nursing homes resident.
So here is my positive answer. A friend did come and went to Microsoft store and downloaded Outlook , as I didn't like Mail. Everything was OK , only outlook was no longer showing in apps and features, but in default apps and features, it's within the new download from Microsoft. I hope with my limited computer knowledge I did help someone at least giving them a clue. So the bit is Go to Microsoft Store download missing app and everything should be OK. Glad I registered as I often need help.
Kind Regards
