  1. Outlook 365 Fails to send message 0x800ccc0F


    I am using Outlook version 1812 build 11126.20196. This morning a wrote an e-mail and my system is unable to send it, I keep getting error 0x800ccc0f or 0x8004210B. Outlook keeps trying to send this e-mail over and over again. I have looked out those codes and followed the suggestions, even re-installed office and nothing helps.

    I wrote the same e-mail again and it was sent out with no problem. I would like to delete this e-mail that is causing the problem, but it is NOT in the outbox. *cry I am getting tired of this send/receive error messages.

    Help please,
    Ak

    :)

    Office 365 outlook will not send message to gmail accounts but receive


    Since updating to Windows 10 my Office 365 Outlook will not send emails - error unable to connect to network - yet it receives them OK and if I go to account settings and use 'Test' it sends and receives OK this is true of all my accounts, Hotmail, gmail and two domain accounts. All can be set up and work from the new Mail App. Have run online repair of Office 365 and rebooted to no avail, anyone any ideas

    This is the exact problem from another's old post. The resolution of SFC / scannow did not show any errors on my computer. It is a new build and the day I added email accounts everything worked and the next I could receive but when I try to send it errors with a 0x800ccc0f code.

    How to enable 'send as' in Outlook (Office 365 email)


    Both. In OWA (web app) the users need to select Show from:

    Outlook 365 Fails to send message 0x800ccc0F [​IMG]


    When doing this first time, the new allowed Send As email is not shown in the From drop down list. Users need to right click their usual Send As address and select Remove, then add the new Send As address manually:

    After that the new address will be shown and can be selected from the drop down list.

    In Outlook desktop app users need to manually remove their usual Send As address and add the new one, thereafter the new address will be shown in From drop down list.
