My email will not load onto my new iPhone 18

Add the mailbox through Outlook’s Google provider sign-in flow, then approve Microsoft’s requested access rather than attempting to sign in with Google credentials as a Microsoft account.

Add the Google account correctly

1. Open Outlook.
2. Tap your avatar in the upper-left corner.
3. Tap the gear icon in the lower-left corner.
4. Under Mail Accounts, select Add Mail Account → Add Email Account.
5. Enter the full Google/Gmail address and tap Sign In.
6. Outlook should redirect you to a Google sign-in page. Enter the Google account password and complete any two-step verification.
7. Scroll through the permissions and tap Allow so Outlook can synchronize the mailbox. ^1^

If Outlook identifies the account as another type, tap Not a ___ account in the upper-right corner, select Google, and sign in again through Google’s page. ^2^

Do not use Sign in with Google to access a separate Microsoft account. Google credentials cannot sign in to a Microsoft account, although the Outlook mobile app can directly display a Gmail mailbox. ^3^

If “Unable to log in” remains

1. Test the same account directly with Google in Safari.
   • If Google also rejects the login, recover or unlock the account through Google. Microsoft directs sign-in problems involving Gmail, Yahoo, iCloud, and other non-Microsoft accounts to that email provider. ^4^
   • If two-step verification appears, complete the verification code prompt; Outlook for iOS supports Google two-step verification. ^5^
2. If Google accepts the login but Outlook does not, update Outlook from the App Store. Microsoft recommends the latest Outlook version when authentication-security changes cause password prompts. ^4^
3. If the account already appears in Outlook, open: Outlook → avatar → Settings → Accounts → affected account → Reset Account. If reset does not work, select Delete Account → Delete From This Device, restart Outlook, and add it again using the Google steps above. Deleting it from the device removes the Outlook connection; it does not delete the mailbox from Google. ^6^

If this is not actually a Google/Gmail address, select its real provider—such as Yahoo or iCloud—during account setup and authorize Outlook on that provider’s sign-in page.
