NimbostratusYes, F5 does support activation of ProPlus, but not in the automated fashion. This is because Microsoft does not support this for domains that are SAML federated.
The behavior observed has nothing to do with federation per se - it has to do with Office software behavior which does not perform automatic activation when SAML federation is used.
The automatic activation on the client side apparently only works while using the old federation mechanism called WS-Fed.
There was a post about an iRule that could implement a WS-Fed federation. See: https://devcentral.f5.com/articles/big-ip-iruleslx-fakeadfs-ws-federation-saml11-24608
