I keep getting this error message in outlook 2013 when attempting to use the todoist add-in. Any ideas?
Please try closing Outlook, clearing the cache for IE (plugin uses this), making sure it's updated to the latest version and accepting all cookies. Then try again.
We are aware of this issue and a few more and are working on a large update that will address this and everything, we hope to have it completed soon.
I will try it...many thanks
