32-bit Outlook 2013 w/ Todoist Add-in Website security certificate problem



I know there's been plenty of traffic on the support pages regarding the Outlook add-in, but much of it seemed to pertain to an expired security certificate in October.

I just downloaded and installed the Todoist Outlook add-in. Unfortunately, the add-in doesn't connect, and I get the following message:

"There is a problem with this website’s security certificate."

In addition to the 32-bit version Outlook 2013, I have the 64-bit version of IE 11 installed.

Please advise.

Hello Paul,

I've tried to use it with Outlook 2013 32-bit, same IE version and it seems to work fine, doesn't return any error messages or certificate issues.

That said, please tell me - are you behind any corporate firewalls or proxy servers?

Best regards,

Sorry - firewall and proxy server. But again, its been working fine for months so I doubt that's the issue.

Same issue. Here is the error I see. It was working perfectly yesterday which was 12/11/2013.

"There is a problem with this website's security certificate. "
"The security certificate presented by this website is not secure."

Hi, Has an updated Outlook client been released yet? Out of curiosity, how do you notify users regarding updates?
