How to fix error code 0x800ccc92 on outlook?
I started to receive the following error message when I click on the send/receive button (or when Outlook attempts to do it automatically), "Receiving reported error (0x800CCC92) "Your email server rejected your login. Verify your user name and password for this account in Account Settings. The server responded: ERR (AUTH) Incorrect username or password". I have made no changes to my username or password.

  • Windows 10
  • office 365
  • all software update on updates
  • PST file is about 3GB
  • Have several email accounts coming and going no issues.
  • I have 4 email accounts, 2 of which have this error code (one is the main/default account) all POP servers
  • I can access those 2 not working accounts via cell, or web with no issues

Here is what I have done thus far and still a problem:

-restarted the computer and network and router

  • rest the password on the accounts (3 times) and confirmed the POP and SMTP are correct, as they are working on the other 2 accounts
  • reduced the size of the PST and cleaned it up
  • Ran scanpst.exe twice
  • ran the office modify to fix any office issues twice
  • deleted one of the accounts (not the main one) then restarted everything and tried to create it but outlook would not allow me and says wrong login and password
  • talked to ATT and couldn't help
  • shutdown Antivirus and firewall
  • ran in safe mode
  • increased the server timeout

I don't know what else I can do, please HELP!!!!

    After several calls to ATT/Sbcglobal, found out they implemented a new password security program that you have to log in to it first before, then update the outlook password. no one can tell me why it affected the two accounts and not the others. but all the emails work know .

    Thanks for the help

    Hi @Teresa Nounou ,

    Does this issue only happen to this specific Outlook client? To confirm if your issue is related to this specific Outlook client, if possible, it is suggested to add these two problematic email accounts to other Outlook clients and see if the issue could be reproduced as well.

    Besides, how did you re-add your email account? Using new Outlook data file or using existed outlook data file?
    As I know, Outlook data files are usually the key factor in similar problems. If you are using existed outlook data file, to completely eliminate the factors from your outlook data files, it is suggested for you to try creating and using a new Outlook profile via Control Panel > Mail > Show profile and add these two problematic accounts with new fresh Outlook data file to see if the issue could be resolved.

    Any update, please feel free to post back.
