AppStream: Accessing virtual labs with Microsoft Office products

This service is for faculty, staff, and students.

Due to our software licensing terms for Microsoft Office and Amazon AppStream, please note that the following situation may occur when accessing any virtual lab containing an Office application.

Choose appropriate account for Office products

After you click the link for your course's AppStream instance, and you authenticate with your St. Thomas username and password, you may be prompted with the following screen:


Select the "AppStream-StreamAccess-MS-Office-Included" option whenever you are accessing a lab with Microsoft Excel, Access, or other Office app, then click "Sign In."


Error: Cross account access

If you do not select the appropriate option at the above prompt, you will receive an error stating, "Unable to authorize the session. Cross account access is not allowed..."

If you immediately receive the above error (you never receive a prompt to select an account), close your browser and attempt to access AppStream again.

If you continue to receive the above error after restarting your browser, open a new support ticket from the App Virtualization (AppStream) service page by clicking the "Submit Request" button, or contact the Tech Desk for assistance.
