Outlook 2016 error 0xCAA70004
Some users report this error message in Outlook 2016. Unable to determine the root cause of the message. Information on the error code is next to none. Any thoughts...?

I had the same issue with MS Teams and Outlook and, for some reason, setting of IE helped me 😄

Go to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
Add a new entry of type REG_DWORD with the name EnableADAL with value 0
Remove the DisableADALatopWAMOverride entry if it exists.
Hi, i had the same problem and corrected it like this:
Access the following registry path
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
Add a new entry of type REG_DWORD with the name EnableADAL with value 0
Remove the DisableADALatopWAMOverride entry if it exists.
Automatically when opening the outlook it will open the popup requesting user and password.Kleber Ramos Thanks a million! Worked great.
Thank you very much Buddy Kleber Ramos this fix my problem.
- It worked for me too
I was getting this same Pop-up, and I was able to fix it by running the office365 diagnostics tool:
https://diagnostics.office.com/The diagnosis was invalid cached credentials, and the tool automatically cleared credentials and restarted outlook.
I recently updated office on my laptop - so credentials may have been cached since before that, resulting in the failure. That's mostly guessing at a cause though.Thank you very much Jett Jones the diagnostics tool worked for me - I'd been struggling with the office sign-in problem for weeks!
- The diagnostic tool worked for me, thanks! I have seen this issue with a number of our users (random and unexplained) however the external DNS does not appear to be our problem. Our helpdesk technician usually ends up reinstalling Office and that solves it. But when it happened to my own computer, the reinstall only lasted a few days then the popup returned. I downloaded the tool and it resolved it within minutes. I hope the fix stays this time! Thanks for the post Jett.
Which steps did you take in the tool? I could not resolve the problem with the tool yet.

Running into same issue!
I am receiving the same error. Any thoughts?
After extensively working with Microsoft Support engineer, we determined that it was an external DNS issue. As the error is intermittent at times. When the pop-up was present, other Microsoft URLs would not resolve. Prime example was https://login.microsoftonline.com, but https://outlook.office365.com would. Other websites and Office 365 services are unaffected. We were not able to determine if the DNS issue was with the local Internet provider or a global provider. It's not much to go on, but somewhere to start.
I have done a quick search about that error code and it seems that somebody has already had a similar issue. It seems that Outlook thinks that you are disconnected from the internet.
Here is the link to the original thread: "https://goo.gl/3Wr2F8"
I looked at the article you mentioned and it has nothing to do with this error code.
