F5 with Exchange 2010

We are trying to configure Microsoft exchange 2010 with BIG IP LTM ( V 10.2.2 ) . All the services like OWA , Active Sync , Outlook Anywhere has been configured in F5 .

I have configured by using Microsoft exchange 2010 predefined template .

My query is we dont have third party signed Certificate . We are using F5 default certificate. Can anyone guide me whether all the above services will work with F5 default certificate .?
