Outlook 2007 will not send/receive

October 2016

There might be times when Microsoft Outlook 2007 fails to send/ receive emails without any changes in the mail settings. In short, Outlook 2007, part of the Office software package, has become non-functional. In these situations an error message is usually displayed for the respective Office software. When the user is unable to send/receive any emails from their Outlook 2007 account, the reason is the rejection of Secure Password Authentication (SPA) by the mail server. When this problem arises, one should open the account settings and uncheck the option of 'Require logon using SPA', though the final consequences of this change remain unknown.

Outlook 2007 will not send/receive


My MS Outlook has suddenly stopped sending/receiving emails. I use Outlook to combine two email accounts, Comcast and Gmail, neither work so I know that the problems lie within Outlook. I keep getting the error message "0x800CCC18 your email server has rejected your Secure Password Authentication (SPA). Please verify your login information in account settings." I have not changed any settings and Outlook is working just fine on another computer with the same settings. Any suggestions? Thank you in advance.


I had the same problem. I had to open my account settings and uncheck "Require logon using Secure Password Authentication (SPA). Once I did that, I could send and receive emails again. I'm not sure of the consequences of doing this though.
