Google Apps and IMAP Invalid Credentials Error

I have pretty much moved all of my email domains and hosting over to Google Apps. It just makes sense – free email, spam filtering, etc. and you can access it via IMAP or POP.  It’s been working great too, but recently I started getting the following error from time to time in my Outlook client:

IMAP: Invalid credentials (Failure)

This was a new error and went away if I clicked on the remember password box and clicked OK, but it was annoying.  Luckily, after some research I found this fix: 

  1. Close your email client
  2. Go to and enter your username and password to unlock the captcha. (Obviously, replace YOURDOMAIN.COM with your own domain name.)
  3. Restart your mail client.

The problem should now be fixed.
