Ok, I understand that there are two options. Using the "Email addresses to receive notice of resource transactions" field will allow for a blind copy of the transaction, which does support the use of the the macro variables.
What I would like is for the "Email addresses to receive blind copies of meeting requests" to also allow for that.
ie.
UserA requests ResourceB
SupportUserC's email is set for "Email addresses to receive blind copies of meeting requests" field
SupportUserC will receive meeting request with ResourceB as the requestor that doesn't include the UserA's information, who was the original requestor.
Is there any way for us to include UserA's information when the meeting is forwarded by ResourceB?
