Mail and calendar app error 0x8000000b

Finally fixed problem with 0x8000000b error on windows 10 phone. Sign in to your Google Acct (not gmail) go to sign in security. Turn ON "allow less secure apps". Go to Outlook on your windows phone. Add account (DO NOT CLICK GOOGLE) go to OTHER and type in your google email address and password - sync and done!

I was having this issue with setting up a Gmail account I had previously had on my Mail App. I fixed it by going to https://myaccount.google.com/u/1/permissions and removing Windows. When I tried to set up the account after this it seemed to work.
