"We can't connect to service you need right now Check your network connection or Try again Later"
I'm getting this error when i'm trying to add a gmail account in WIndows 8.1 Mail app.
This also comes when i click on a gmail account that needs attention and after this i got the error but meanwhile the other email on my mail app working perfect-ably and no problem with the internet either.
Will thankful for your suggestions.
