please try to clear the cache and cookies from Internet Explorer.
If this won't help, please go to the same option menu as mentioned earlier, but this time instead of "Clear SSL State", click the "Certificates" button, then access the "Trusted Root Certification Authorities" tab, find "Equifax Secure Certification Authority" on the list and click Remove.
If this still won't help, uninstall the Todoist for Outlook plugin with the Add/Remove Programs option in the Control Panel (it will be listed as OutlookTodoist), then re-download and re-install it again and let me know if you still experience this issue.
