I had my Outlook open and downloaded the newest version of CCleaner yesterday and after running the standard clean my Outlook no longer recognizes either of my Gmail accounts with their 2-step authentication and app-specific passwords. I tried updating the login info in the correct way, and also tried deleting the accounts entirely from Outloook and starting over, and it will not accept the account logins no matter how, or how many times, I reset them. So my question is, why is this new version of CCleaner doing this and how do I fix it? Or otherwise, how do I revert to the file I created before running the cleaner and I'll just delete CCleaner as no longer worth the hassle and use another program. Thank you for your help.
Just thought I'd link to this in case it gave you any thoughts.

Hmm maybe just an extreme coincidence in timing. Thank you.
