Gmail Outlook Send Receive Error 0x800CCC0E
Hi folks, many clients are calling me to fix this error code. Microsoft updated their security and it is disconnecting the past Gmail credentials. You need to create a new connection.
There are some steps posted on Microsoft’s website, but before you try these yourself, be sure that you are technical enough to get through the instructions. Some of my clients have tried and failed and ended up with more problems. I can help you, this should be a 5-15 min fix. My hourly rate is $325, and you get 4-15 min appointments with this hour, so that would leave you some time to use my services in the future.

My instructions are below: Step 1 is not always necessary.
Step 1: Remove access for Microsoft Apps & Services in Gmail.
- Close Outlook.
- Sign in to your Google account on google.com.
- Select your profile picture in the top corner and select Manage your Google Account.
- On the left side menu, select Security.
- Scroll down to Your connections to third-party apps & services and select Microsoft apps & services.
- Locate Microsoft apps & services has some access to your Google Account and select See Details.
- Under Access you’ve given to Microsoft apps & services, select Remove all access.
- Select Confirm.
Step 2: Delete the Google IMAP credentials from Windows Credential Manager
- From the Windows Start menu, search for Credential Manager and open it. On Windows 10 you may need to open the Control Panel to access Credential Manager. For more information, please go to Accessing Credential Manager.
- Under Manage your credentials, select Windows Credentials.
- Scroll down to Generic credentials and locate those starting with MicrosoftOffice16_Data:OAUTH2.
- Expand each of these and hover over MicrosoftOffice16_Data:OAUTH2 until it shows the full name including the tp_google_imap_Oauth2. These are the Google credentials for your Gmail account.
- Select Remove for each of these with the MicrosoftOffice16_Data:OAUTH2. There are two of these credentials for each Gmail account so make sure you remove both.
After you have done the steps above you are now ready to Sign in via browser from Outlook. Open Outlook to the Outlook profile that was not syncing and select the Sign in via browser business bar in Outlook. Make sure during browser sign in to check the box for Microsoft apps & services noted at the top of this article.
If you removed the Gmail account from your Outlook profile, select File, Add account to add the Gmail account back again and do the browser sign in process again.

This is an error I got when I was helping a client setup a Gmail account in her Outlook. When it won’t connect, I do a series of things to get it working. See list below. Then if these fail, it’s usually McAfee. You have to run the McAfee removal tool, just uninstalling it does not work. This might not work for you but removing McAfee is a good first attempt, then try the rest. It’s so buggy with Outlook and it’s deeply embedded firewall. Microsoft and Google are fighting with this all the time, very hard to keep up with.
Things to try
Turn on “less apps” in Google security
Be sure 2-step is on in Google security
You can setup an app password but the new Microsoft connector doesn’t need it
Uninstall McAfee/Run the full removal software
Disconnect the current Microsoft connectors in Google security
Verify all Office and Windows updates are current
Outlook will maybe have a sign in prompt after doing all this, then you can “sign in” and it might not take the first time, relaunch Outlook and it should work.
