It works fine if I manually provide access tokens but those expire in 1 hour.
So, whenever I try to do one of the following :

• skip giving access token in createTransport function


• provide expired access token


• provide a expires value prior to current date

In each of the the above case I get an error 'unauthorized_client' with code: EAUTH, command: AUTH XOAUTH2

Simply, Nodemailer is not generating new access token but throwing errors.

I am providing the following while creating transport: type, user, clientId, clientSecret, refreshToken, accessToken and expires.

I have also tried providing authentication details in message options as given in 5th example here but that also doesn't works.

Please help me get out of this and thanks in advance.

  Could you please provide a sample of your code? Google's Using OAuth 2.0 for Web Server Applications documentation is really good and has a link to their Google APIs Node.js Client repo which has some useful code samples. Alternatively, you could look at Let less secure apps access your account which is simpler to implement but doesn't provide the same sort of robust options as OAuth2.
