Updated on July 9, 2021 | by Evan Chase

Are you unable to configure Gmail in Outlook? You need to be extra cautious because this situation can put your crucial data at stake. So, if Outlook cannot connect to Gmail, you need to try some corrective measures which we have mentioned below. Read all the provided methods and use them one by one so that you can fix the Gmail and Outlook configuration issues. One main symptom of the Gmail and Outlook connection issue is the repeated denial of username and password, no matter how many times you’ve entered it correctly.

How to Fix “Unable to Connect Gmail in Outlook?”

We have the best solutions for you, but make sure you know how to connect Outlook to Gmail. 

After that, try the below-listed solution. 

Solution 1: Enable IMAP Settings on Gmail 

Though you can use the POP protocol, it is usually not recommended as it is an outdated protocol and has rigid sync capability. Therefore, using IMAP over POP will give you more benefits such as flexibility of managing your account on different devices, and better server sync. To exemplify, with IMAP everything remains up to date, such as while using Gmail in Outlook, IMAP will mark the read emails on Outlook just as they are on Gmail so that no confusion happens. But with POP, you will get the least convenience hence it worth ditching.

However, Gmail uses IMAP for every email account thus enabling it is not always necessary but if you enable it manually you will be sure that it’s working for you. If it won’t be enabled, you will certainly face difficulty in using Gmail with MS Outlook. So, if you are unable to use Gmail on Outlook, make sure IMAP is enabled on Gmail.

To Enable the IMAP on Gmail, you need to follow these steps:

  1. Open your browser, go to Gmail.com and sign into your account.
  2. Now, go to Settings by clicking on the gear icon Settings from the top-right corner. And then “See All Settings”. 
  1. Access the “Forwarding and POP/IMAP” tab.
  1. In the “IMAP Access” menu select “Enable IMAP”.
  1. Click on Save Changes.

Solution 2: Check Gmail SMTP & other settings in Outlook

  1. Go to Managed Connected Accounts option in Outlook.com
  2. Now, make sure that you are providing correct information. Use the table given below to match the Gmail SMTP settings on Outlook.

  • Port: 993

Solution 3: Enable Folders

Outlook needs certain permissions to access your Gmail folders. Therefore, you must allow Gmail to access the folders that are meant to use in IMAP.

  1. From your browser, sign in to Gmail.com.
  2. Access the Settings by clicking on the gear Settings icon from the top-right corner.
  1. Click on the “Labels” tab.

Solution 5: Re-Configure Gmail in Outlook 

  • Configure Gmail in Outlook 2019:

Important Note: Having two-factor authentication is quite important as we mentioned above, else you may end up having connection errors while configuring Gmail to Outlook. 

Now, let’s begin with Outlook 2019 with Gmail. Do this, if you are not able to use Gmail on Outlook. Try these steps:

  1. Open Outlook, click on File option.
  2. Select Add Account
  3. In the next window, you need to provide the Gmail address. First type your Gmail address, as user@gmail.com. The email address should be complete. 
  4. Click on “Connect” and till it takes information.
  5. A new window will open for “Password”. Here, use the two-factor authentication password/app password. You are advised to use the one-time-use password instead of using the primary account password.
  6. Allow Outlook to access your Gmail account.
  • Configure Gmail in Outlook in 2016

If you are using Outlook 2016, you can’t use the app password as it doesn’t support two-step verification, 2FA. The account setup process is not entirely different from that of Outlook 2019. However, you can get the app-specific password. 

Important Note: If you are not able to access Outlook 2019, you can have an app-specific password and use it instead of using the sign-in process. 

If Outlook is not connecting automatically, you can add details manually. To set up manually, try with the following steps:

  1. Open Outlook, click on File.
  1. Now, click on Add account.
  1. Click Manual Setup or additional server types and then Next.
  1. Now, select POP or IMAP and click “Next”
  1. Type in your name first and email address. Enter imap.gmail.com in the incoming mail server, and smtp.gmail.com in Outgoing mail server (SMTP). Click on More Settings.
  1. Now, do not select the option Require logon using Secure Password Authentication (SPA) as this option is not supported by Gmail, because it is a proprietary Microsoft protocol based on NTLM authentication.
  2. In the “Outgoing Server” select “My outgoing server (SMTP) requires authentication.”
  1. Now, in the Advanced Tab, select SSL so that encryption is enabled for the Incoming server (IMAP). Enter 993 for IMAP, and select TLS for the outgoing SMTP server and enter 25 to 587 in the port number. Click OK.

This is it. If you are having a connection issue, try using the app password. 

Solution 6: Check the Connectivity for Gmail TCP Ports

If you are facing issues while connecting Outlook to Gmail, make sure that your computer and internet service provider is not blocking the network ports that are used for accessing Gmail. 

You can check ports on Windows 10, use the Test-NetConnection PowerShell cmdlet in PowerShell. Then, you have to check the availability of Gmail servers as IMAP over SSL (993) and SMTP over TLS (587).

To launch the elevated PowerShell, click Win+X – Windows PowerShell (Admin) and run the command: 

  • Test-NetConnection imap.gmail.com -port 993
  • Test-NetConnection smtp.gmail.com -port 587

If you receive TcpTestSucceeded = False in returns, the Gmail account is blocked by a firewall. So, check the Windows Firewall or third-party antivirus settings of your device and make sure that there is no network filtering option available. Allow the outlook.exe process to make sure that outgoing traffic is directed over TCP ports 993 and 587. If any of the ports are blocked, contact your Internet service provider as some network equipment may be blocking the ports.
