    1

    Check that your Gmail is working normally first

    ~20s
    Open your web browser and go to gmail.com. Sign in if needed. If your email loads normally here, your Gmail account is fine — the problem is with the connection between Gmail and your email app. If you cannot sign in to gmail.com either, go to accounts.google.com and follow the prompts to recover your account.

    Re-add Gmail in Microsoft Outlook on your phone

    ~35s
    Open the Outlook app. Tap the three horizontal lines (≡) in the top left → Settings (gear icon) → tap your Gmail accountRemove Account. Then tap the plus (+) icon to add an account → select Google → sign in with your Google account credentials. Outlook will open a Google sign-in page where you approve the connection. This uses the new sign-in method and should restore full Gmail access.

    Quick Tip

    Quick Tip: Make sure you have the latest version of Outlook installed — old versions of Outlook do not support Google's updated sign-in. Update Outlook through the App Store (iPhone) or Google Play Store (Android) first.

    Quick Tip

    ~21s
    Open the Outlook desktop app. Click FileAccount SettingsAccount Settings → select your Gmail accountRemove. Then click New → Email Account → enter your name and Gmail address → click Connect.

    Turn on two-step verification if you haven't already

    ~24s
    While you are managing your Google account settings, this is a good time to turn on two-step verification if you have not done so. Go to myaccount.google.com → Security → 2-Step VerificationGet started. This adds a second check when signing in from a new device, which helps protect your Gmail from unauthorized access.

    If Gmail suddenly stopped loading, sending, or syncing in Outlook, Apple Mail, or another email program on your phone or computer, the most likely reason is a change Google made to how Gmail accounts log in to third-party apps.

    Google used to allow email apps to sign in to Gmail using a username and password the same way a person would. Starting in 2024, Google ended this older method — called Basic Authentication — and now requires all apps to use a newer, more secure sign-in system called OAuth 2.0. Apps that have not been updated to use this system will stop connecting to Gmail.

    The fix is not complicated. You remove your Gmail account from the email app and add it back again. When you add it back, the app will use the correct, updated sign-in method and connect to Gmail successfully.

    This is not a problem with your Google account, and nothing is wrong with your Gmail itself. You can still access all your email normally at gmail.com or through the Gmail app on your phone. The issue is only with third-party email programs.
