Hi Unisys,
Unable to Launch Application You do not have access to this application or the application has been removed.
In the O365 App in Cloud Manager, make sure under "User Access" the application is deployed to a role that the user(s) is a part of.
It sounds like the user is trying to access O365 via SP-Initated login, but after they log into the Centrify portal, they do not have rights to access the application, so the app launch gives the above error.
