I'm unable to get any Call Answering Rules to record and play a custom message and just get the mailboxes standard greeting.

When I create the rule I can click the button for it to call me and then lets me record a message, but unlike Exchange 2010 in 2013 it just says abour recording a greeting rather then the call answering prompt message you get in 2010.

I have seen http://community.office365.com/en-us/forums/158/t/185191.aspx but there was no answer as to when it would be released.

I'm having the same issue but in Exchange 2010
