# GMAIL OAUTH issue

 * Hi
 * I seems to have run into a conflict of Goole API versions.
 * I am switching WP SMTP to use OAUTH on gmail, I also have another plugin installed“
   Simple calendar” that also uses google to get to a calendar.
 * When I change the WP SMTP config to use gmail and try a test email it causes 
   wordpress to detect a failure.
 * If I disable the Simple Calendar it works OK.
 * I am hoping you can help

 * Hi [@mickwall](https://wordpress.org/support/users/mickwall/),
 * Unfortunately, we have a known issue with the ‘Simple Calendar’ plugin due to
   the conflict with the different versions of Google API the plugins are using.
   We are giving a thought about this.
 * Alternatively, please switch to other [available mailers](https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/),
   or with the Gmail SMTP service.
 * I apologize for any inconvenience caused by this in the meantime.

 * Thanks
 * I have managed to use “composer” to update the google api used by the google 
   calendar plugin and this has solved this for now.
 * For anyone else, I used this command
 * composer require google/apiclient
 * from the google calendar plugin directory.
 * Many thanks.

 * Hi Mick,
 * Glad to know you sorted it out and thanks for taking the time to let us. Hopefully,
   Simple Calendar updates the Google API they’re using soon.
 * Have a good one! 🙂
