When you are checking for new mail you might receive one of the following errors.
Tip: In many cases error codes are identical between Outlook and Outlook Express. If you search Bing for an error code and find a site which discusses Outlook Express, check it out. Because Outlook and Outlook Express both use the same underlying technology, the cause and the solution may be the same for Outlook.
Error Codes
#5.5.0 smtp;553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
This means the server you are trying to send to is blocking mail sent from your server. You'll need to contact the recipient's administrator or send your message using a different mail server.
553 5.7.1 Sender address rejected: not owned by user
This means you are not using the correct outgoing (SMTP) server authentication settings.
In Outlook 2007, go to Tools, Accounts Settings. In Outlook 2010 and 2013, go to File, Account Settings. Double click on the email account then click More Settings. Select Outgoing Server tab. Select Log on using and enter the username and password that can send using this SMTP server. Enable SPA only if your server supports it.

Thanks for sharing this informative blog. I face issues regarding Outlook Sending reported error 0x80042109.
you need to check your account and port settings. Typically, you need to use SMTP port 587 for the Outgoing Server and encryption as TLS. Check the Outgoing server tab and set it to My Outgoing Server requires Authentication option. Both of these are in Account settings under more Settings.
Task 'purchase@unigastt.com - Sending' reported error (0x80042109) : 'Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'
Do you have the correct SMTP port and SSL/TLS setting? Also check the Outgoing Server settings, many servers require you to enable the My Outgoing Server requires Authentication option on the Outgoing Server tab.
Task 'doc.control@yan3pdp.com - Sending' reported error (0x800CCC6C) : 'Your outgoing (SMTP) email server has reported an internal error.

yes diane,still we have same issue. I don't know what I have to do .lease help me out.
sorry for not getting back to this sooner - i was told there were issues that were fixed in mid-june. Was that your experience?
You saved my day.
I was debugging my eXchange setup with https://www.smtper.net
and i caught an 0x800CCC78.
Please help me! I have no idea why, but whenever I try to send a message from my outlook account, it won't send and I immediately get an email back from the System Administrator saying that my message "did not reach some or all of the intended recipients" AND "This message could not be sent. Try sending the message again later, or contact your network administrator. The client operation failed. Error is [0x80004005-0x000b22-0x000501]."
I have spent hours online trying to figure out why this is happening suddenly for no reason and how to fix it. No luck so far.
And the WEIRDEST part of all this is that I have 2 hotmail accounts set up under the same profile in my outlook 2010 - and this only happens with one of them, At this very moment, one account will send just fine - and one won't. Makes no sense. PLEASE HELP ME. :(
Also please note that i am NOT a techy person so any answers need to be in layman terms or explained simply. Thanks so much!
Suddenly when emailing two employees within the office who both have gmail accounts from my own domain they are not receiving and no bounce back message???
If you are on exchange server, ask the admin to look into it - the exchange logs will show if it was handed off to Google. If so, the problem is on their end. An aggressive spam filter would be my guess in that case.
