Problem installing Mail and Calendar App in Win 10 Pro Insider 18908

With the new 18908 Insider my Mail and Calendar app stopped working (would not update new emails). I uninstalled the app, ran the Troubleshooter and SFC /Scannow etc. Using Windows Store I tried to re-install but I get a message that says it can't install. Message says " It's a problem on our end and try later".

Any thoughts? Is there a direct download link on a Microsoft site?

Solved! I didn't received any help on this site so I went to AskVg and searched for: [Guide] How to reinstall All Default Built-In Apps in Windows 10. Found this in Option 2 of the solution.
Run PowerShell-Admin. Then copy and past the script below. It takes a few minutes to complete. Now all defaut built-in apps including Mail and Calendar work.

Get-AppxPackage -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}
