Configuring Other Email Clients

If you are using an app that accesses your Google account with only a username and password, take one of the following actions to switch to a more secure method and continue to access your email, calendar, or contacts. If you do not take one of the following actions, when LSA access is discontinued after February 15, 2021, you will begin receiving an error message that your username-password combination is incorrect.

Email

  • If you are using stand-alone Outlook 2016 or earlier, move to Office 365 (a web-based version of Outlook) or Outlook 2019, both of which support OAuth access. Alternatively you can use G Suite Sync for Microsoft Outlook.
  • If you are using Thunderbird or another email client, re-add your Google Account and configure it to use IMAP with OAuth.
  • If you are using the mail app on iOS or MacOS, or Outlook for Mac, and use only a password to login, you’ll need to remove and re-add your account. When you add it back, select “sign in with Google” to automatically use OAuth.

Calendar

  • If you use CalDAV to give an app or device access to your calendar, switch to a method that supports OAuth. We recommend the Google Calendar app [Web/iOS/Android] as the most secure app to use with your G Suite account.
  • If your G Suite account is linked to the calendar app in iOS or MacOS and uses only a password to login, you’ll need to remove and re-add your account to your device. When you add it back, select “sign in with Google” to automatically use OAuth. Read more

Contacts

  • If your G Suite account is syncing contacts to iOS or MacOS via CardDAV and uses only a password to login, you’ll need to remove your account. When you add it back, select “sign in with Google” to automatically use OAuth. Read More
  • If your G Suite account is syncing contacts to any other platform or app via CardDAV and uses only a password to login, switch to a method that supports OAuth.

Note: If the app you are using does not support OAuth, you will need to switch to an app that offers OAuth, or ask your admin to contact the supplier of your app and request that they add OAuth as a way of connecting your Google account.
