OUTLook Connectivity in SSO environment

We are rolling out Time Tracking in Workfront for our organization of nearly 700 folks. We are using SSO with SAML 2.0 and have OKTA for 2 factor authentication outside the firewall. Every time I start the Outlook Add-In, I have to retype the login URL (43 characters). With all of our other security controls, it would be awesome if the Add-In could remember my Workfront URL.
