Error Message in Irule while setting up Exchange 2010
Oct 31 07:54:28 local/tmm1 err tmm1[7417]: 01220001:3: TCL error: vs_Exchange_2010_OWA_INT_single_Persist_IRule_irule - Operation not supported (line 3) invoked from within "CACHE::disable"...
The iRule looks good. Can you comment out the CACHE::disable commands and see if the error persists. Do you have a relevant profile assigned to the VS that enables caching?
