Exchange 2010 email signatures
Posted on 2010-09-14
I have created 2 transport rules in Exchange 2010 SP1 to attach email signatures due to Exclaimer not supporting 2010, the second rule is the main one and that works without any problem.
The first rule attaches a slightly modified signature for users who do not have a mobile number specified in their AD user, the exact Condition is 'When the sender's properties contain specific words' and the way I have written it is mobilenumber: ^$ to try specify a null value.
The first rule never seems to work and the second rule ends up attaching the signature with a blank part for where the mobile number usually is.
