Hi @Alberto68
For our better research, please provide more information about this case:
- What does the pop-up asking for the password look like? Can you provide a screenshot (please be careful to cover your personal privacy information.
- Is the web version of Gmail working?
- What is Outlook client version? Please make sure to upgrade to the latest version.
There are many reasons for this issue, try these are a few possible solutions:
- Check if you have Outlook saved credentials (passwords) stored in Windows Credential Manager. (Control Panel>All Control Panel Items>User Accounts>Manage your credential > Windows Credentials.)
- Gmail accounts have two-factor authentication enabled, which requires you to enter a verification code or use an app-specific password when signing in from a new device or app. Outlook may not handle this process smoothly and may constantly ask you for your password. To resolve this issue, you can disable two-factor authentication in your Gmail settings or use an app password instead of a regular password when adding your Gmail account to Outlook.
- Try logging in to Gmail for the web. If everything is fine with Gmail.com, considering that it may be caused by corrupted profile/data files in Outlook client, it is recommended that you try to create a new profile (Control Panel >Mail >Show Profile >Add) and add an account to test to check if there are some differences.
