I recently had to change my email password, as properly dictated by work's IT policies. I use offlineimap to get my mail, mu4e to read it, and smtpmail-send-it to send it.

(setq message-send-mail-function 'message-send-mail-with-sendmail
      message-send-mail-function 'smtpmail-send-it
      smtpmail-stream-type 'starttls
      smtpmail-default-smtp-server "pod51019.outlook.com"
      smtpmail-smtp-server "pod51019.outlook.com"
      smtpmail-smtp-user "dgempesaw@sharecare.com"
      smtpmail-smtp-service 587)

Offlineimap manages its password stuff from a config file at ~/.offlineimaprc. I updated that file and I was able to continue retrieving my mail with no hiccoughs. I then updated my ~/.authinfo file as well with the new password, but I continued to get the authentication failed error.

Sending failed: 535 5.7.3 Authentication unsuccessful in response to base64-encoded-password

That was pretty odd, considering that I changed the source file and all. I tried digging through smtpmail.el a little bit, looking for occurences of password or auth or something. I happened to see a defun called auth-source-search which got me into auth-source.el. Doing an apropos-command for "auth" led me to auth-source-forget-all-cached.

Apparently the auth sources like ~/.authinfo are cached for a customizable length of time, so I just had to clear the cache and everything is back in running order!
