Cannot start Microsoft Outlook.

healee 31

I have been using Microsoft Outlook 2010 on Windows 10 to read and write Gmail messages for years since I retired and have had no problem. Today I added in an email account from outlook.com. Since then the Outlook wouldn't open and gave two messages. A quick search from the Internet. I've found that Microsoft no longer support Office 2010. I would like to be able to continue to use 2010, not buy any more software. I'll give up adding the outlook email account to the Outlook 2010. I have been spending hours to stop Outlook asking for the credential for the Outlook email account credentials to no avail. I have uninstalled 2010 and reinstalled 2010 and made no difference. Below are the two messages. Please help me to revive my 2010.

There is no Mail in Control Panel. I can only find Email & accounts.

Please see attached pic and advise.

Hi @healee ,

Welcome to our forum!

According to your description, it's suggested that you could create a new Outlook profile (Control Panel>Mail>Show Profiles>add) and then add your accounts to check if there're any differences.

On the other hand, considering that you have encounter the password prompt issue, it's suggested that you could refer to the following thread to troubleshooting: Why does Outlook keep prompting for password.

Since the support for Office 2010 ended on October 13, 2020, and there will be no extensions and extended security updates, you can still use your office programs. For your better user experience, it is recommended that you use a newer version of office. For more information, please refer to: End of support for Office 2010.

Perhaps you can tell me where Outlook 2010 stores mail profiles in Windows 10 Home so that I can either delete and create a new profile or simply delete the email address of outlook.com from the current profile that is causing me heartache. Is it in the registry or just somewhere on the hard disk?

Since I can't open Outlook, I follow https://support.microsoft.com/en-us/office/remove-a-profile-d5f0f365-c10d-4a97-aa74-3b38e40e7cdd#:%7E:text=How%20to%20Delete%20a%20Profile%20in%20Outlook%202010,profile%2C%20then%20select%20Remove%20.%20.%20See%20More by typing "outlook.exe /manageprofiles" into the windows 10 search box and pressing Enter but nothing comes up.

Then I open the command prompt and do the same I got an error saying the argument is not valid.

I checked https://support.microsoft.com/en-au/office/command-line-switches-for-microsoft-office-products-079164cd-4ef5-4178-b235-441737deb3a6#Category=Outlook, and there is no such switch.

Hi @healee ,

To create a new Outlook profile in Outlook 2010, follow these steps:

Click on the Start button and select Control Panel. Where is Mail in Control Panel? Mail appears in different Control Panel locations depending on the version of the Microsoft Windows operating system, Control Panel view selected, and whether a 32- or 64-bit operating system or version of Outlook is installed. The easiest way to locate Mail is to open Control Panel in Windows, and then in the Search box at the top of window, type Mail.

In the Control Panel, click on Mail.

In the Mail Setup dialog box, click on Show Profiles.

Click on Add to create a new profile.

Enter a name for the new profile and click OK.

Follow the prompts to add your email account to the new profile.

There's no profile to be found as reported before. I had attached an image of the search result before. Please take note that mine is Windows 10 Home system.

I don't get the same screen. I don't even get view by small icons. Could you please tell me what I've missed.

Hi @healee ,

Looks like you open Settings, just close it and search Control panel in the search box in the bottom left corner.

Thank you I've found the mail profile via the Search Box. I didn't know Settings and Control Panel are two different things
