Sending, receiving, and organizing email in Outlook.com
Hello, I’m Virginia a fellow Windows user.
The password to your Hotmail imap would be the same as for your Hotmail account, if you can’t remember it then check your browser’s password manager to see if the information is there.
Usually an email client would automatically enter the same details for imap & smtp as added in the username & password boxes during setup.
If you’re trying to add the email account to a non Microsoft email client then you may require an app specific password which is used instead of the account’s usual password.
Otherwise try:
or the forgotten password option shown when logging into the account online.
