      I get a '403 Error' when signing into my Qualifier account

      When I try to sign into my account, I keep getting this error-message instead.

      When using OAuth, the email address used to authenticate must remain the same throughout the process. This means you can't change the email used mid-process.

      Troubleshooting Steps

      • Make sure you're not entering or selecting a different email address on Office365 than was originally entered on Nylas.
      • Make sure you're not attempting to log into an alias. You must authenticate with the main account.
      • If the issue persists, log out of all Office365 accounts, and then try again.
      • Alternatively, try authenticating from an Incognito or Private browser session.
