I am looking to create some transport rules for outgoing email based upon AD properties.
eg. Phone: 123-456-7890
Where the actual inserted code looks like "Phone: %%PhoneNumber%%", retrieving the phone number from AD. That part works fine.
Setting up my transport rule, I include the following conditions:
However, that condition doesn't work. I've tried it without the single-quotes, without the preceding ^. Really, all I want is for the rule to make sure that %%PhoneNumber%% is not empty.
Anyone know how to make Exchange do that?
