Cannot start Microsoft Outlook.

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 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.

    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.
