We're seeing a few errors from Outlook users after upgrading to Windows 10, specifically a message reporting problems sending messages. The affected users receive error 0x800CCC13.
'Task 'email address alias@domain.com- Sending' Cannot connect to the network. Verify your network connection or modem.'
Microsoft is looking into it, but one fix we know works is to open a command prompt as an administrator and run sfc /scannow. Reinstalling or repairing the Office install, making new profiles and other common troubleshooting steps will not fix this issue.
To use the System File Checker right click on the Start button and select Command Prompt (Admin). (You'll need to click Yes to allow it to make changes to the computer.)
When the Command Prompt appears, type (or paste) sfc /scannow then hit Enter (there is a space between sfc and /).
Once System File Checker is finished, reboot the computer.
Users are reporting that System File Checker reports corruption in mlang.dlI.Mui and Windows.Media.Speech.UXRes.dll.mui. SFC replaces the files and after a reboot, Outlook works again.
I have faced the problem where I couldn't send mail from outlook in Windows 10. Then I was going through the internet searching for the perfect solution of the error. But after seeing your blog I was satisfied with the way of explaining the process of how to fix the error.
Got the proper solution thankyou so much!
This solved my problem thanks
My Windows version is Windows 7 - Outlook 2016 after upgrading from Outlook 2007 can't send mail from any profiles. Looking forward to that Microsoft update to fix this problem
I recently update windows 10 - I also bought and installed Office 365 - my Outlook mail will no longer allow me to RECEIVE I can send but I have to hit the FORWARD cause the Send button is not there - I have repaired I have Changed the setting in control program for incoming and outgoing made sure ports were right numbers repair, rebooted, I am stumped I dont know what to do next HELP
Have you tried adding a new account (or removing your account and adding it back)? No Send button usually means there isn't an account or outlook doesnt 'see' the account because of corruption.
I cannot send/receive any emails in my outlook account. Keeps prompting me to enter my password. I didn't even know I had a smpt and imap password. What can I do? Thanks!
The password should be the same for both, but if outlook has problems connecting, it will ask for both. Did it work as expected before? it could be a temporary problem with the internet or the mail server.
Do you use two factor authentication on the account? if so, you need to use the app password in outlook.
error Ox800CCC78"
I have tried ''sfc /scannow'' twice They both stopped at 57%
Did you try making a new profile?
If you use 3rd party security software that installs outlook addins, try restarting outlook in safe mode - if it works ok, then an addin is the likely cause, 3rd party security addins are often the cause.
The scan worked and problem solved...many thanks.
