Setup Gmail on Office Outlook365

Hi, have look here: https://support.microsoft.com/en-gb/office/add-an-email-account-to-outlook-for-windows-6e27792a-9267-4aa4-8bb6-c84ef146101b#picktab=classic_outlook You may need to go to Google to setup security and generate a password.

To update the Gmail password in classic Outlook for Microsoft 365 and fix the IMAP setup issue, use these steps:

1. First, confirm IMAP is enabled in Gmail (already done, but verify):
   • In a browser, go to Gmail.
   • Select Settings (gear icon) > See all settings.
   • Go to Forwarding and POP/IMAP.
   • Under IMAP Access, make sure Enable IMAP is selected.
   • Select Save Changes if needed.
2. Make sure Outlook is not requiring SPA for the Gmail IMAP account:
   • In classic Outlook, when adding the IMAP account manually, on the IMAP details page ensure Require logon using Secure Password Authentication (SPA) is unchecked. This is required for IMAP accounts such as Gmail.
3. Re-add the Gmail account from Control Panel so Outlook prompts for credentials:
   • Close Outlook.
   • Open Control Panel in Windows.
   • Select Mail.
   • Select Email Accounts....
   • On the Email tab, select New.
   • Enter name and Gmail address.
   • Enter the password in the Password and Retype Password boxes.
   • Select Next and follow the on‑screen steps. Outlook should now prompt for and store the updated password.
   • When account setup completes, select Finish and reopen Outlook.

If Outlook still does not accept the password and shows messages about needing an app password, generate an app password in the Google account and use that instead of the normal Google password when Outlook asks for the password.
