what is the most efficient way to create a distribution group and populating the group with external phone numbers for text messages. I tried creating the group via the emc i could not copy paste the phone numbers. I tried via the exchange management console The phone numbers below is a sample. We have approx. 180 groups to create. We have about a thousand phone number to enter in Exchange. Because they are external phone number would I have to create mail contacts - which I cannot copy paste phone numbers
