Hi, we're using BES for Exchange 4.1.7 which also isn't listed in the affected software list. I know the KB says "If you are using a software version that is not listed above, update to one of the listed versions before applying the interim security software update." when it comes to the list of patches however this is quite diffferent from saying that previous versions are vunerable. We will be upgrading to version 5 this year but until we do so do we need to implement the workarounds or are we safe?
