But isn't there another big disadvantage for external users? I'm setting up external users with a Reviewer license and no Federated ID and un-checked use SAML only. When we @ mention them in an update, it sends them and email (to their external email) , which is great. BUT if they use the link in that email to try to "see it in Workfront," it prompts for the SSO (Microsoft) login first. I know that we can send them the external login url (with .../login) but it'll be frustrating not to be able to use the links! I called tech support and they said basically they can't do anything. All we can do, it seems, is tell the external users to first go in Workfront and get logged in. Then, while they're logged in, the links will work. This will not make them happy. Anyone found a better way??? Mavis Moon
