I have had Outlook working for some time. Recently our company moved from an
MS Exchange server for mail to an ISP based service not using Exchange. I
modified my settings and was able to send and receive mail. I deleted my VPN
connection to the MS Exchange server and the Exchange based account
information. Sometime after that point I have found that I am unable to send
mail on any of several accounts although I am still able to receive mail.
The message I receive is: Task 'pop.xxxxxxx.yyy - Sending' reported error
(0x80040201) : 'Unknown Error 0x80040201'. I have "repaired Outlook. I use
Norton Antivirus to scan outgoing mail and I have tried running without
outbound scanning enabled. I am able to send and receive test messages on all
accounts from within the e-mail account set up Wizard with its Test Account
Settings feature. I appreciate receiving help on this problem. Thank you.

Norton is notorious for interfering with Outlook, even with the option
disabled. YOu may have to uninstall it and reinstall without the scanning
option.

In truth, that doesn't test the entire path out and back in again.
