Mail app only working occasionally

[geoffllo]

1. My Windows 10 seems to be fine, except for the mail app inbox and notifications.
   
   I have checked all the settings, but they must be correct anyway, because occasionally, an email arrives correctly in the inbox and I get a notification correctly. Then the next few just don't arrive, but interestingly, when I click on "All mail" they are all there.
   
   I have removed my (GMail) account and then reinstated it, but that made no difference.
   
   I have tried to uninstall the app using Powershell, but it asked me for "parameters" and I didn't know what to do at that point.
   
   Any ideas, please, as to how to make the inbox and related notifications work correctly?
   
   Geoff

This is a fix for an older version of Win 10 but may help? Create a restore point first:
