I have outlook and it keeps asking for windows security password which I know is correct because its the same password I use to log into everything else....every-time I put the correct password in it goes away and comes right back....what is the issue???

Do you have 2-factor authentication enabled for your account? If so, you need to use an app password as Outlook won't bring up the second dialog.

Hi,

Which type of email account are you using? Exchange, POP3 or IMAP?

Outlook keeps prompting for password could be caused by several reasons, such as:

Outlook is configured to prompt you for credentials
Incorrect password cached in credential storage
Required Authentication Settings for outgoing server and incoming server
Outlook Anywhere is not configured to use NTLM Authentication
Corrupt Outlook profile
Slow or unstable network connection
Antivirus programs
Shared calendars

You may refer to the following forum article for a general troubleshooting steps:

Hope this helps.
