Hi all, I'm using O365 Nintex app, and I'm having issue the workflow process. I remember I have done that before and it was working on the other SharePoint online site. I have one Gmail account and I shared my SharePoint online site with that by adding that email in one of the groups that have Full Control, ones I got the Shared Email notification I access the site and signed up with Live user account. I'm able to login to the site and able to create and submit the forms. But one workflow process where I'm just assigning the Task or sending even an Email notification on the initiator or on the email, I'm getting HTTP Unauthorized Error.
That is not possible it was working for O365... Nintex Live is not yet supported in Office 365.
You can share your SharePoint Online with external users, however Nintex Live is not present there.
