Gmail and Outlook issue: Your IMAP server wants to alert you of the following: Invalid Credentials (Failure)

Last updated on

You’re sure you’ve entered the correct password but Outlook keeps giving you this error? This is because Gmail blocks access from some email clients such as Outlook for security reasons. Try the following steps to resolve the issue:

1. Allow access to your Google account

As a security precaution, Google may require you to complete this additional step when signing into a new device or application. To allow access, visit https://www.google.com/accounts/DisplayUnlockCaptcha and follow the steps on the page. If you use Gmail through your work, school, or other organization, visit https://www.google.com/a/yourdomain.com/UnlockCaptcha In the web address, replace yourdomain.com with your domain name.

2. Allow less secure apps

Try changing your Gmail account settings to allow less secure apps to access your Gmail account.

  1. Go to the “Less secure apps” section in My Account.
  2. Next to “Access for less secure apps,” select Turn on.
    (Note to G Suite users: This setting is hidden if your administrator has locked less secure app account access.)

G-Suite users only:

  1. Log in to G-Suite administrator console
  2. Click Security > Basic settings.
  3. Under Less secure apps, select Go to settings for less secure apps.
  4. In the subwindow, select the Allow users to manage their access to less secure apps radio button.

Once you’ve set Allow users to manage their access to less secure apps to on, affected users within the selected group or Organizational Unit will be able to toggle access for less secure apps on or off themselves.

3. Enable IMAP

Is IMAP enabled in your Gmail account? In Gmail, click the cog wheel (top right) to go to Settings > Forwarding & POP/IMAP and make sure IMAP Access is set to Enable IMAP
