How To Fix ‘Outlook Cannot Connect To Gmail Account’ Issue?


If the Outlook client is not connecting to the Gmail or the login details are not authenticated, then we will let you know the steps to fix this problem. Most of the users complain that they keep on getting the same message on the screen that prompts them to enter the username, password, and server.

After some time, you will find an error on the screen. This error basically pop-up due to the authentication issue. The authentication must not be enabled on the Gmail account. Now, let’s have a look at the steps to troubleshoot this problem.

How to get rid of Outlook cannot connect to Gmail?

To begin with, enable the POP/IMAP protocol to get Gmail.

Enabling POP/IMAP in Gmail

Sign-in to the Gmail account and check the gear-icon from the top of the page. Go to ‘Settings’. Here you will find the ‘Forwarding and POP/IMAP’ option. If both the protocols are disabled, then enable anyone. We recommend you enable IMAP. Once done, tap to save changes.

The reason why we recommend IMAP protocol is the special protocol it has for providing fast communication between the server and email client. What this means is if you perform some activity on your Outlook from the web browser mail, then the same changes will appear on the Outlook simultaneously. Whereas, this doesn’t appear in the case of POP.

Connecting Gmail to Outlook

  1. Over to the ‘Start’ menu and search for ‘Open your outlook’ option. Tap ‘File’> ‘Add an account’.

  1. Choose ‘Manual setup and additional server’ and press ‘Next’.

  1. From the opened window, select either POP or IMAP and move to the next step.

  1. Now, enter the name that is going to be displayed in the email you forward to any email address. Select ‘IMAP’ as an account type and enter the incoming server address accordingly. In the outgoing mail server, enter Don’t forget to enter the login information in the form and tap ‘More settings’.
  2. Here, you will find ‘Login using secure password authentication’ option. Uncheck the box given next to it as this is Microsoft protocol of NTLM authentication. This is not at all supported by Gmail.

  1. Hover to Outgoing server and click on the option, which says ‘My outgoing server requires authentication’.

  1. Now, you will find the ‘Advanced’ tab from where you need to change the email server settings. After that, you need to select SSL for encrypting your connection for the incoming server (IMAP), which you can by selecting from the drop-down list. Enter ‘993’ in the port number for IMAP. As for the SMTP server, you will have to select TLS as an encryption protocol. Also, make sure to change the port number to 587 (if it is 25).

If this problem occurs due to the disable the basic authentication for the Gmail account. It’s been multiple years since Google has taken a decision to strengthen the protection of accounts by barring apps that use simple validation for accessing the Gmail mailbox, which includes Outlook. As of now, Outlook does not support OAuth and two-step verification, so the only way to permit a connection for Gmail via Outlook is by using an app-specific password, and this feature can only be enabled on Google Account webpage.

Steps to enable this feature from Google Account:

  1. Launch your web browser and log in to your Gmail account.
  2. Click on your account pic given on the upper right corner and press ‘My Account’.
  3. In the ‘Sign-in & Security’ section, press ‘Apps with account access’ link.

  1. Scroll down and you will find ‘Allow less secure apps’ option, so make sure to enable this option by following these steps:

  1. Enable 2-step verification.
  2. Go to ‘App Passwords’ to generate a new password for the Gmail connection from Outlook.

  1. From the ‘Select app drop-down’ list, you need to select ‘Mail and Windows computer’ as the device type.

  1. Press ‘Generate’ button to allow Google to generate a new app password.

  1. Make sure to use the password (excluding the spaces) rather than your password from Google account while connecting to Gmail in Outlook.

After doing that, go to Outlook and try to connect again with the newly created password.

After setting up everything properly, you will find the successful completion of both test tasks that you have done to verify the connection to Gmail. As the process completes successfully, you will see the problem of Outlook not connecting to Gmail getting vanquished.
