Hi All,
I have a user that wants to email to one of our static email list which has about 3000 members. The use is getting a message in outlook saying the Email List contains at least 1000 recipients. I'm not sure if this is a new email list limitation or just a mailtip. I don't want to send out the email until I get some clarification on the message. I thought the email list counted a 1 recipient.
Thanks in advance for you help.

    Yea, thats expected!
    The group counts as one recipient as far as established limits, but what you are seeing is just the mail tip letting you know its a large group
