What To Do If Outlook cannot connect to Gmail account

In case when your Outlook is not connecting to Gmail and your credentials are not accepted, you may want to fix that. In this article we will show you how you can do that. The problem is that Outlook keeps asking you to provide Server, User Name and Password and there is no matter how many times you click on Ok, it keeps popping up.

After some time it gives you an error. This issue occurs when basic authentication has not been enabled for a Gmail account. So we need to get rid of this situation. So let’s configure Outlook and see how to resolve the error (you can also take a look on our guide on how to setup Gmail in Outlook 2016).

How to solve Outlook not connecting to Gmail issue

So, the first thing we need to do is to enable POP/IMAP.

Enable POP/IMAP in Gmail

Log into your Gmail account and click on Settings. After that, go to Forwarding and POP/IMAP. Here you can see that Status: POP is disabled and Status: IMAP is disabled. You can choose either one of them, but we are going to enable IMAP. Once it is done, click on Save Changes.

The reason behind selecting IMAP is that IMAP is the communication between your web mail and e-mail client and e-mail client that we use is Outlook. It means that if you open your mail on web browser and perform some actions on Outlook, then you can see the changes turn to Outlook instantly and appear on the web mail. This is not a case with POP.

Connecting Gmail to Outlook

Now go to the Start menu and open your Outlook. Click on FILE and then click on Add Account.

From here select Manual setup or additional server types and click on Next. In the following window select POP or IMAP and go ahead.

Now type in your name and email address. As the account type select IMAP and as incoming mail server type type in imap.gmail.com. Outgoing mail server is going to be smtp.gmail.com. Also, you should fill the Logon information form and then click on More Settings.

Go to Outgoing Server and tick on My outgoing server (SMTP) requires authentication. Now, go to Advanced and use SSL to encrypt your connection by selecting from the drop-down list. The port number for IMAP should be 993. Do the same thing for SMTP and the port number should be 465. Click on Ok and go ahead.

Now you can see, that there is the same form we have earlier. We still cannot connect to Gmail, but the error is not the same.

So, as explained in the beginning, this issue occurs due to the fact that you have not enabled the basic authentication for your Gmail account. Let’s see how to enable this feature from your Gmail account.

To enable the basic authentication, you just need to go to your Gmail account and then click on your profile picture and then go to My account. From here scroll down and click on Sign-in & security. From the left section select Connected apps & sites. Scroll down a little bit and you will see the option Allow less secure apps. You need to enable this option.

Once it is done, go to Outlook and just try to connect again. As you can see, the process is completed successfully and you will see that there is no Outlook not connecting to Gmail problem.

That’s all, your Outlook account for Gmail has been configured now and issue when Outlook not connecting to Gmail is solved. It will download all your mails and synchronize all the information.

    What happens when you keep getting this after everything’s been enabled and every setting is correct?

  • Ranbir Kaur

    The advice to switch off secure authentication is not smart at all.

    Read this how to do it right:


    You basically need to create a special password for any app using your gmail. Which is very secure and smart.

    Thank you SO much. I read about a dozen posts trying to figure this out. Yours was the only one that successfully connected my gmail account to my MS Outlook 2016 desktop client. You rock!

  • jacko

    HI I have tried all your instructions and still cant connect my GMAIL to OUTLOOK??
    any more ideas ??

    • Frank Carbonaria

      I tried the same, no success. I also used the gmail page https://accounts.google.com/b/0/DisplayUnlockCaptcha to give access, no success

      Finally I decided to use the default mail client on my windows 10 system, got a popup to trust my system and finally the default mail client was working.
      Then I tried outlook 2016 again, and now it is working. That was the only solution to get my system in the list of trusted connections.


      • David Norman aka DAN

        How do you ” use the default mail client on my windows 10 system”?
