Outlook - "Unknown Error" Ox800CCC81

December 2016


I have a friend who is suddenly unable to send emails. Can receive, however the Error Message is "unknown error" Ox800CCC81.
Help would be most appreciated


This is what I did to fix the problem, opened Microsoft Office Outlook
  • Click"TOOLS"
  • Under options clicked on TAB "Mailsetup"
  • Click----half way down "Send and Receive button,
  • Opens and click on Edit button,
  • Click on button" Accounts properties",
  • New window shows "Internet E-mail settings"
  • Click tab on top " OUTGOING SERVER",
  • Tick "Log on to incoming mail server before sending mail"
  • Click OK

Then try to do a test, send yourself an email.
This will fix the problem!


Thanks to Wendy for this tip on the forum.
